Machine for fastening the valve 20 is at the lower section of the front end section of the main body 21 directed towards reinforcing rods 22, the two sections of the base plate 23, which abuts the reinforcing rods 22, and between the two sections 23 of the base plate includes a hook for twisting 25 having at its front end a groove for insertion of the wire 24.

Hook for cables 25 can be rotated by means of motor 26. Prior to the start of rotation of the motor 26 of the hook to twist 25 is in position remote from the wire 7, moreover, the groove for insertion of the wire 24 are oriented so that it is parallel to the wire 27, which has the shape of a loop so that the wire 27, bent in the form of a loop, could easily be introduced into the groove for insertion of the wire 24.

The hook to twist 25 is held by means of the motor 26 by means of the mechanism for extending and retracting 29. The mechanism for extending and retracting 29 is formed, for example, by means of a Cam mechanism and adapted for insertion of the wire 27 in the groove for insertion of the wire 24 of the hook to twist 25, when the motor 26 starts to rotate and the hook to twist 25 is allocated to the standby position, when the rotation of the motor 26 is stopped.

Thus, when the trigger device include, to start rotation of the motor 26, the hook to twist 25 is shifted in the direction of the wire 27, and after the introduction of the wire 27 in the groove for insertion of the wire 24 hook for twisting rotates, and when the opening operation of the starter hook 28 stops rotating and returns to the standby position.

The main body of the machine for fastening 21 has a passage for the wire 30, through which is passed a wire 27. The passage for the wire 30 extends from the rear end section of the main body of the machine for fasteners 21 to the guide section 31 for when Ruciane wire. The guide section 31 is bent in an arc and has a passage for the wire 30 in the form of a groove, open on the inner side of the arc. On the section of the passage for the wire 30, the rear section of the main body of the machine for fasteners 21 is a gear wheel 33 mounted on the motor output shaft 32. A gear wheel 33 goes into the hole (not shown)provided in the passage of the wire 30, and presses the wire 27 to the lower section of the passage for the wire 30. When the microswitch 33 is enabled by means of the starting device 28, the motor 32 rotates, which allows you to feed the wire 27 to the front or rear of the main body of the machine for fastening 21. Forward and reverse rotation of the motor control 32 is performed by the control circuit (not shown), which is located in the main body of the machine for fastening 21.

In the position of the passage for the wire 30, in which he comes to the guide section 31, provides a means of gripping and cutting wire 34. The capture tool and the cutting wire 34 includes, for example, two areas of engagement and two cutting edges, the wire 27 passes between the two parts of the grip and between the two cutting edges. When the rotation number of the wire 27 that is defined on the basis of the number of revolutions of the motor 32 reaches the specified number, the capture tool the cutting wire 34 captures the tail section of the wire 27 by means of two sites of capture. When the front end section of the wire 27 is wound around the reinforcing bars 22 in the form of a loop, and the rear end section of the loop is captured using two sections of capture, produce twisting by means of a hook for twisting 25 for binding (binding) reinforcing bars 22, and then the two cutting edges are pressed toward each other to cut off the wire 27.

On the rear end of the main body of the machine for fastening 21 formed in the support section 35 to the drum. On the support section 35 provides for the installation shaft 36 in such a way that it acts (issued). The body of the cartridge 40 is installed with removable installation on the shaft 36. Inside the cartridge 40 is installed drum 41 (see Fig 1 and 2). In the case of the cassette 40 is formed a hole (not shown)through which the pull wire 27. The opening of the cartridge case 40 extends into the passage for the wire 30.

Figure 1-5 shows a variant of the cartridge case and drum machines for fastening fittings. The housing of the cassette 40 is part of the machine for fastening the valve 20.

Figure 1 and 2 shows how the drum 41 is installed in the housing of the cassette 40. The housing of the cassette 40 is made of plastic material with high wear resistance and Flexural strength, such as polypropylene, and from the bottom portion 44 of the cartridge case 40 is a shaft for mounting the drum 43, in which to mount the drive mounting shaft 36 of the support section 35.

The upper portion of the cartridge case 40 is open to the introduction of the drum 41, and a stepped section 42 is formed on a part of the cutting edge of this hole. In the notch 42 on the inner side of the stepped section 42 includes a site outside edge of the large flange 55 of the drum 41, and the hole of the cartridge case 40 is closed by a section of outer edges of the large flange 55, which prevents the wire 27 to go outside of the large flange 55.

Cylindrical shaft for the drum 43, in which is inserted the installation shaft 36, protrudes from the bottom portion 44 of the cartridge case 40, and the outer edge surface 45 of the shaft to the drum 43 is formed by mounting recess 46, going around the axis of the shaft to the drum 43.

In this embodiment, a mounting recess 46 formed in the form of a ring on the outer edge surface of the shaft to the drum 43. To ensure easy fixing drum 41 in the housing of the cassette 40, the installation recess 46 is formed at a predetermined height of the shaft to the drum 43, the section gear 48 tooth gear 47 of the drum 41 is included in the installation recess 46 that prevents separation of the drum 41 from the housing of the cassette 40.

While mounting recess 46 formed in the form of a ring with a rectangular configuration in cross-section, may also be formed from two up to eight slots with RA is different angular intervals from each other. When mounting recess 46 formed in the form of a ring, then attach the drum 41 is facilitated, and when the mounting recess 46 formed in the form of multiple shifted from each other cavities, tooth gearing 47, after its passage over one installation recess 46 when the drum 41 rotates, is included in the following installation in the recess 46, so that the drum 41 capable of intermittent rotation for the application of the braking action, thereby preventing any possible entanglement (entanglement) wire 27 caused by the rotation of the drum 41 while idling.

Position 49 marked with a lock hole for fastening of the cartridge case 40 to the wall of the main body of the machine for fastening 21 with the bolt, when the housing of the cassette mounted on the mounting shaft 36.

Figure 3-5 shows the configuration of the drum 41. The drum 41 is formed of plastic material with high wear resistance and Flexural strength, such as polypropylene; wire 27 is wound around the drum 41 and can be moved to the front or rear of the main body of the machine for fastening 21 by submission with a gear wheel 33. The drum 41 can rotate in forward and reverse directions depending on, leaves the wire 27 or she wound (wound back).

The drum 41 is a plot of the hub 41A, around which numot is on the wire 27, large flange 55 and the small flange 50. Large flange 55 formed in such a way that it is located on the side of the hole of the cartridge case 40, and the small flange 50 formed in such a way that it is located on the side of the base 44 of the cartridge case 40. Due to the fact that large flange 55 is provided on one side of a section of the hub 41A, even when the molding shrinkage has on the peripheral wall of the cartridge case 40, prevented loss (separation) of the wire 27, as large flange 55 closes the gap 56 between the peripheral wall of the cartridge case 40 and the drum.

In the Central part of the hub 41A formed hole of the hub 51, in which is inserted a shaft for mounting the drum 43, and the two notches 52 formed on the inner peripheral surface of the hub hole 51 in positions opposite each other, while the tooth of the gear 47 is formed in each recess 52.

Meshing teeth 47 are in the direction of the intermediate part of the area of the hub 41A from the regional section of the hub hole on the wall of the large flange 55; at the same time they are walking along the shaft to the drum 43, the lifting of the grooves 52, and the meshing teeth have at their front ends parts of the gearing 48, protruding in the direction of the center hole of the hub 51. The parts of the gear 48 are rectangular in configuration, which allows them in which contain the installation in the recess 46 of the shaft to the drum 43. Mounting recess 46 has a cross-section of rectangular shape and is formed, as has already been mentioned here previously, in the form of a ring covering the outer perimeter of the shaft to the drum 43; mounting recess may also contain several notches formed offset from each other.

Meshing teeth 47 formed in such a way that they are somewhat inclined relative to the center hub hole 51, so that the force of elasticity can be created through the shaft to the drum 43, when install the shaft to the drum 43, and the tabs section of the gear 48 is fixed in the mounting recess 46. Needless to say, the direction in which the tines gearing 47, may not be inclined.

Moreover, the force of elasticity of the teeth of the gear 47 creates frictional resistance, which allows the drum 41 to rotate, when the wire 27 will have to unwind, and stops the drum 41, when the unwinding of the wire 27 is stopped. Since the mounting recess 46 formed in the form of a ring, the teeth of the gear 47 can be connected with the shaft for the drum 43 from any angle.

In the case when the mounting recess 46 formed at intervals from each other on the outer perimeter of the shaft to the drum 43, in the case where the drum 41 rotates, the teeth zateplenie pass over the edges of some of the installation grooves 46 and again included in the other mounting recess 46, so possible intermittent stops when the drum 41 rotates. Moreover, it is also possible to form many ledges at the base of the mounting recess 46 in the form of a ring along the perimeter of the shaft to the drum 43.

Large flange 55 and the small flange 50 adjust the deviation in the direction of the thickness of the wire 27 wound around the site of the hub 41A. Large and small flanges 55 and 50 as much as possible simplified to reduce the cost and weight. In a large flange 55 formed in the installation groove 53 for fixing the end portion of the beginning of the winding of the wire 27.

Moreover, the elastic element type coil spring (not shown) is wound around the supporting shaft 130, and the cover 100 is forcibly displaced in the direction of opening by means of this elastic element.

The plate 132 is installed to rotate in the second accommodating recess 81 of the cartridge case 70. As shown in Fig, the plate 132 is formed in the form of a ring and has six engagement grooves 133-138, located at equal intervals from each other; of the six engagement grooves 133-138 arbitrary against the opposite notch gear 133 and 136 are formed as through holes. The notches engage 133-138 pass over the optical sensor 87. Moreover, formed gradients a-a with an inclination in the direction of the engagement grooves 133-138.

At the outer peripheral edge of one of the end plates 132 includes a flange 139 which is in contact with the outer edge of the second accommodating recess 81. The pad 132 is injected into the second accommodating recess 81 so that the notches engage 133 - 138 facing the cover 100, and the movement in the axial direction of the shaft to the drum 79 is prohibited by means of the elastic ring 140, such as a snap ring, is introduced in an annular groove 78 formed on the shaft for the drum 79.

Let us now turn to the consideration pig-21, which shows the drum for wire 150.

On Fig shows the front view of the drum for wire 150. Drum for wire 150 is made of a plastic, such as ABS polymer or polyethylene, and has two flanges 152 and 153 on the respective sides of the section of the hub 151, around which is wound the wire 27. The plot of the hub 151 has a cylindrical configuration and is made in the form of a whole with two flanges 152 and 153. Despite the fact that the area of the hub 151 mainly has a cylindrical configuration, the area of the hub may have some other polygonal configuration.

Two flange 152 and 153 are formed in the form of discs of different diameters, p is item the height of the flange 152 of smaller diameter, measured from the peripheral surface of the hub 151 to plot the outer peripheral edge is greater than the height of the unused wire 27 wound around the site of the hub. The height of the flange 153 of larger diameter is large enough to allow you to keep winding the tail section 27E unused wire 27 without excessive bending from the state in which wound unused wire 27. Due to the differences of the diameters of the two flanges 152 and 153 of the drum for wire 150 mounting method wire 27 can be easily determined when securing the drum to the machine for fastening the valve 20.

In the Central part of the hub 151 is formed a hole 155 in which is inserted a shaft for mounting the drum 79 machines for fastening the valve 20. The plot edges of the mounting holes 155 having a large diameter, forms a flat surface 156, which is one step lower than the flange 152, and six protrusions 157 are formed on a flat surface 156. Between adjacent protrusions 157 are formed the notches 160 with surfaces of the inner wall 158 and 159, coaxially with the flange 152. Moreover, the protrusions 157 are formed on parts of the wall 161 between adjacent grooves 160. On the other side of the area of the hub 151 is formed by six notches 162, which entered the protrusions 157.

Six protrusions 157 and six grooves 162 loc the wife so the full layout configuration is mainly hexagonal. Arcuate surface of the inner walls of the grooves 163 162 on the side of their outer peripheral edges, coaxially with the mounting hole 155, and six protrusions 157 introduced in such a way that their parts of the edge surface 165 in the immediate vicinity of the outer peripheral edge of the flange 153 have the frictional resistance with the inner surfaces of the walls 163, which accounts for the six protrusions 157 and six grooves 162 are connected to each other.

Thus, in this embodiment, two flanges 152 and 153, which, when the winding of the wire 27 to regulate the movement in the direction of the thickness of the wire 27 wound around the site of the hub 151, protrude from the area of the hub 151 and section 156 of one side surface of the hub 151 or section 166 of the other side surface of the hub 151 comprises protrusions 157 or recesses 160 as a means of connection, through which it is possible mutual connection.

While in this example, the tool connection formed by the six protrusions 157 and six grooves 160, the number of protrusions 157 and grooves 160 may be at least equal to two or three. Moreover, instead of the protrusions 157 may be formed of one arcuate ledge, running coaxially with the plot of the hub 151, and the recess 160 is configured such Kotor which allows you to enter this arcuate ledge. Moreover, the means of connection may be formed using a variety of arcuate protrusions that can be connected together, with one projection has a smaller diameter and the other is a larger diameter.

Moreover, Fig protrusions 157 are shown as thin. This is because there is shown a section along the line III-III of the drum for wire 150 Fig, and, as shown in Fig, the notches 160 and 162 have a wide openings due to shrinkage. The flange 153 on the plot side edges of the mounting holes 155 formed a stepped section, which allows the introduction of nuts, retaining rings and the like, for mounting the drum for wire 150, so as to prevent its separation.

In addition, as shown in Fig and 19, in the immediate vicinity of the mounting holes 155 section of the hub 151 is formed a cylindrical hole 168 for detecting the rotation position of the drum for wire 150. On the site of the machine for fastening the valve 20, which forms the area of rotation for opening 168 can be installed with the light-emitting element and svetoprinimayuschego element (photodetector), and about the state of rotation of the drum for wire 150 is judged by passing holes 168 between two specified elements. Painting mainly in the form of blades formed on the outer peripheral edges of the flanges 152 I, represent shallow recesses 169 and 170, which help to reduce the wall thickness of the flanges 152 and 153.

On Fig shows the configuration of the flange 153 of large diameter. On the area of the outer peripheral edge of the flange 153 is formed a hole 171 for the introduction of the wire going in the direction of the area of the hub 151. Hole 171 for insertion of the wire has, at a height corresponding to the end portion of the winding 27E wire 27 (see fig.16b), guide hole 172, going in the direction in which the wire 27 is wound around the site of the hub 151. Of the guide hole 172 is a plot of retention 173, intended to hold the wire 27, and the protruding portion of the plot of retention 173 captures and holds the tail part of the winding 27E wire 27.

Moreover, the formed groove 174, running from the guide hole 172 in the direction of the area of the outer peripheral edge. The plot coming from the groove 174 to the outer peripheral section 175, flexible, and at the other edge of the hole 171 for the introduction of a wire formed of a section of the cutout 176. As the wire 27 is directed to the outer side of the flange 153 to the outer peripheral section 175 of the groove 174 of the applied force, which bends it inward from the wire 27 to the inner side of the flange 153; however, due to the elastic force generated from the em flexibility of the outer peripheral section 175, the tail part of the winding 27E wire 27 can be introduced into the groove 174 and fixed in it.

Moreover, due to the presence area of the cutout 176 tail part of the winding 27E wire 27 is experiencing a small bend or even no. Moreover, as it is held within the groove 174, the tail part of the winding 27E wire 27 can be maintained at the site of the edges of the plot hold 173 without bending in the radial direction of the drum, at the height of the winding of the wire 27.

Thus, the tail part of the winding 27E wire 27 is curved, so that when the wire 27 is held in the guide mechanism of the machine for bonding wire, the tail part of the winding 27E wire 27 is separated from the site of retention 173 and holes 171 to the input wire, and the tail part of the winding 27E wire 27 may be passed unchanged into the guide mechanism of the machine for fastening wire, so there is no need to straighten the bend.

Hole 171 to the input wire is also used in the case when, after the introduction of the end portion of the beginning of the winding 27S wire 27 in the recess 177 (see Fig(C) and 16(d)), used as a front end section of the introduction section of the hub 151, the area of the end winding is directed to the annular surface of the hub 151 between the flanges 152 and 153 through the area of the hub 151. Viem is and 177, which entered the tail part of the start winding 27S, formed in the flange 153 on the side surface of the hub 151, and is provided by the surface of the base wall 179 to support the end portion of the beginning of the winding 27S. Moreover, in the lateral area of the plot of the hub 151 is formed by adjusting the notch 180, which entered the tail part of the start winding 27S to regulate this movement.

When the winding of the wire 27 and the tail part of the start winding 27S wire 27 is introduced into the front end section of the introduction 177, and the tail part of the start winding 27S bend between the flanges 152 and 153 through adjusting the notch 180 provided on the section of the side wall of the hub 151, and begin winding the wire 27 around the peripheral surface of the hub 151 in this state; however, if a large force F in the direction of winding is applied to the wire 27, the tensile force F can be perceived boundary plot holes 171 to the input wire.

Moreover, in the immediate vicinity of the adjustment notches 180 tail part of the start winding 27S wire 27 is again bent 90 degrees in accordance with the wall thickness of the flange 153 and wall thickness area of the hub 151, from a state in which it goes in the direction parallel to the flange 152 (the X direction), in a state in which it goes in the direction perpendicular to the flange 153 (direction Y), in the direction in which the elongated adjusting the notch 180 (Z-direction), and, moreover, in the X-direction, so that a large force is required to stretch this stretch in a straight line. Moreover, since the recess 177 supports put a lot due to the surface of the supporting wall 179, there are many sites that perceive the tensile force F, and the wire 27 can be easily extended due to the efforts with which the machine for fastening the armature pulls the wire 27.

Thus, if in a machine for fastening the valve 20 drum repeatedly rotates in forward and reverse directions, the movement of the end of the start winding 27S wire 27 in the direction of the circumference of the drum is regulated by regulating the notches 180, so that the tail part of the start winding 27S wire 27 is gradually detached from the site of injection, resulting in its separation is prevented.

Due to such construction, if the number of wire 27 remaining on the drum is decreased during the operation of fastening the valve using the machine for fastening the valve 20, it is possible to eliminate the Department of the bent portion of the terminal segment of the beginning of the winding 27S from the drum, which causes clogging in the guide wire machine for fastening fittings. Thus, during the operation of fastening the valve can in order to avoid which stops operation due to clogging of the wire 27.

In accordance with this variant of opposite ledges A and B drum for wire 150 have different heights. While the protrusions 157 contain high ledges A and low ledges V, which are interleaved. On the upper end of each of the protrusions A and B formed moderately curved recess S.

As shown in Fig, a reel for wire 150 is injected from the side of the small flange 152 in the housing of the cassette 70 by introducing the shaft to the drum 79 of the cartridge case 70 in the hole 155. The protrusions 157 injected into the notches engage 133-138 pads 132.

As for the protrusions 157 entered in the notches of the gear 133 and 136, the high ledge A and the lowest ledge W are located opposite each other, and the notches of the gear 133 and 136 are formed as through holes, so that the optical sensor 87 may detect a high ledge A and the lowest ledge W. Optical sensor 87 includes a light emitting element and svetoprinimayuschego element, and, as has already been mentioned here earlier, because the upper ends of the protrusions 157 are formed in the form of curved grooves S, light from the light emitting element after reflection going on svetoprinimayuschego element that allows to reliably detect the protrusions 157.

Small flange 152 is introduced into the first accommodating viemku. The gap between the outer perimeter of the small flange 152 and the inner perimeter of the first accommodating recess 80 is less than the diameter of the wire 27, so there is no danger of output (drop) wire 27 from this gap. Large flange 153, outer diameter that is larger than the inner diameter of annular wall 92 of the cartridge case 70, entered into sliding contact with the upper end of the annular wall 92 and is not included in the body of the cartridge 70.

When the cover 100 is closed by rotating around a supporting shaft 130 by overcoming the elasticity of the elastic element 131, the front end of the shaft to the drum 79 of the cartridge case 70 includes a cylindrical protrusion 110, and is also included in the installation recess 154 formed in the area of the hub 151 drum for wire 150. Moreover, half 116 of the shaft gear 115 of the locking element 120 is introduced into the hole 83 of the shaft to the drum 79, and a plot of rotation 111 rotates through SitePlayer finger on managed finger levers 112, 113; when the locking element 102A of the cover 100 is in the second notch gear 125, the groove gearing 119 half 116 is engaged with the wall of the gear 85 of the shaft to the drum 79, the lid 100 closes the housing of the cassette 70.

When a parcel of rotation 111 is rotated to engage the locking element 102A of the cover 100 with the first notch gear 123, the groove sacale the Iya 119 half 116 is separated from the wall of the gear 85 of the shaft to the drum 79, the cover 100 is opened automatically due to the elasticity of the elastic element 131. As mentioned here previously, when the cover 100 closes the housing of the cassette 70, the guide 108 of the first section 101 of the cover is in sliding contact with the side surface in the immediate vicinity of the outer peripheral edge of the large flange 153 of the drum for wire 150, thereby regulating the axial movement of the plot of the hub 151 drum for wire 150.

As mentioned here previously, the locking means 120 can adjust the protruding length of the shaft gear 115 by adjusting the ring element 121, 26 so that, as shown in Fig, you can change the distanceandbetween the guide 108 of the cover 100 and the upper end of the annular wall 92 of the cartridge case 70. When the protruding length of the shaft toothing 115 locking means 120 increases, the specified distance is also increased; when the protruding length of the shaft of the gear 115 is reduced, the specified distance is also reduced. In accordance with this variation of wall thickness trimmer annular element 121 is changed stepwise from the first installation site a to the fourth installation section 121d, so you can have a 4-speed regulation specified distance; however, the number of steps is not the Ogre is socialsim, so you can use more or less than four stages.

As shown in Fig and 27, the large flange 153 of the drum for wire 150 is located between the guide 108 of the cover 100 and the upper end of the annular wall 92 of the cartridge case 70 and is held between the guide 108 of the cover 100 and the upper end of the annular wall 92. To ensure proper rotation of the drum for wire 150 requires large flange 153 was pressed through the efforts of the clamp cover 100, which is within the specified range.

The contact pressure is large flange 153 is changed in accordance with a distanceand; when distanceandlittle, then the contact pressure is large, and when the distanceandgreat, then the contact pressure is small. When the contact pressure is large, the frictional resistance of the large flange 153 increases, which hinders the rotation of the drum for wire 150. When the contact pressure is small, large flange 153 can hang out in a certain range, this creates a gap between the large flange 153 and the upper end of the annular wall 92; when the wire 27 is in the gap it becomes impossible to properly rotating drum for wire 150.

Thus, depending on the distanceandchanges the contact pressure, and if the contact pressure is selected incorrectly, then there is Nara is giving normal operation, such as incorrect feed or return (winding and rewinding) of the wire 27. Distanceandis defined by a gap formed in the case, when the cover 100 closes the housing of the cassette 70 and locked by means of locking means 120; whereas it is desirable that this distance was constant during Assembly this distance is not constant due to the manufacturing tolerances of each component.

In accordance with this variant of the locking means 120 provided with an aligning ring element 121 having the first to fourth mounting sections a-121d with different wall thickness, and dip the ring element 121 rotate for fastening with screws locking means 120 on the respective installation sites a-121d trimmer annular element 121, which you can adjust the protruding length of the shaft gear 115 and to set the distanceandso even in the case when distanceandis incorrect due to the manufacturing tolerances of each component, it is possible to adjust the distanceandso it was optimal. Thus, it is possible, for example, to correctly set the contact pressure with which the cover 100 is pressed to the drum for wire 150 that allows you to select the contact pressure is within the specified range.

While distanceandfluctu the plans due to the rotation of the trimmer annular element 121, cover 100 may not be pressed against the housing of the cassette 70 with a force that exceeds a constant level specified through engagement between the engagement grooves s and 92b of the cartridge case 70 and the engagement protrusions 1 0 2 and 102b of the cover 100. Moreover, while in the above case, the distanceandcannot be properly chosen due to the manufacturing tolerances of the cartridge case 70, the cover 100 and the locking means 120, the variation width of the drum for wire 150 can also be absorbed by adjusting the distanceandthat allows you to select the proper contact pressure is within the specified range, in order to prevent erroneous filing or return wire, using the drum for wire 150.

As has been described here previously, the locking device is mounted on the element opening/closing (on the lid 100)provided on the main body (the body of the cassette 70) and allows opening and closing, and locking device comprises a locking means 120 and an aligning ring element 121, thus locking the tool 120 has a plot of rotation 111 and the shaft gear 115 formed on a plot of rotation 111, and an aligning ring element 121 has many installation sites a-121dc different wall thickness, mounted rotatably on the shaft of the gear 115. Application : what is the main means 120 may be installed on the installation sites a-121d. When the locking device is mounted on the element opening/closing (on the lid 100), the shaft gear 115, introduced into the main housing of the cassette 70), acts of the element opening/closing (cap 100), and choose an installation site that has the locking means 120 trimmer annular element 121, which you can adjust the protruding length of the shaft toothing 115.

The cover 100 is in contact with the inner side guides (step sections) 92A-a of the cartridge case 70, and the engagement protrusions 102b and 1 0 2 engages with the engagement grooves 92b and C formed in the guide 92A annular wall 92 for installation in the specified position, with the side wall 104 of the second area 105 of the cover is connected with the other marginal edge of the second bottom portion 75 of the cartridge case 70 that allows you to completely close the housing of the cassette 70.

As has been described here previously, the housing of the cassette 70, which holds the drum for wire 150 is installed (fixed), using screws or other similar items on the machine for fastening the valve 20 with the configuration shown in Fig and 24. As mentioned here previously, small flange 152 of the drum for wire 150 is in the first accommodating recess 80, and the large flange 153 is in sliding contact with the upper konzo the annular wall 92 of the cartridge case 70, so if the wire 27 leaves or rewound by means of a gear wheel 33, there is no fear that the wire 27 will be separated from the small flange 152 and the large flange 153. Moreover, due to the difference of the outer diameter of the large flange 153 and the small flange 152 enclosing the space 88 is secured, and a containing space 88 can bend the wire 27, arising in the case, when the wire 27 is wound. About the state of rotation of the drum for wire 150 can be judged by detecting a higher ledge A and less high ledge W using the optical sensor 87.

While in the above-described embodiment, a large flange 153 of the drum for wire 150 is not located in the housing of the cassette 70, but is in sliding contact with the upper end of the annular wall 92, the outer diameter of the large flange 153 may also be in the body of the cartridge 70, and the gap between it and the annular wall 92 of the cartridge case 70 is chosen smaller than the diameter of the wire 27. When the outer diameter of the large flange 153 selects the specified image specified by enclosing the space 88 is also protected by the difference in outer diameter of the large flange 153 and the small flange 152, and there is no fear that the wire 27 will be separated from the small flange 152 and the large flange 153.
