The invention relates to the textile industry and can be used in bessoltseva spinning.

A feature of open-end spinning method is a grouping of separate fibers in the complex for rotating the support surface and the formation of mechanical complex sliver, twisted out of the rotating base is riadenie core yarn simultaneously with the formation of the sliver in its middle is introduced serdechnikov (core) product. Otherwise, the method is not changed. Sliver is twisted, forming around the core (artificial filament, wire) outer fibrous layer having an actual twist. This serdechnikov product may be subjected and not subjected to false twist (SU 183107 A, 08.08.66).

Feature pneumatic spinning method is the concentration of elementary fibers of the rotating air flow in the complex and twisting it into yarn. When the spun core yarn fiber complex twists serdechnikov product, creating its fibrous outer layer (SU 445210, A, 06.10.75).

Closest to the claimed method is a known method of forming single and core yarn in bessoltseva spinning, which consists in the separation of the fibrous tape at the elementary fibers, the concentration on the support surface and the introduction of a rotating device for forming a fibrous sliver and twisting them sliver at the outlet of the yarn (SU 465447 A, 13.11.75).

However, in this method concentrated on a rotating perforated support surface cone-shaped fiber is subjected to the influence of centrifugal forces and is not possible save is formirovaniya single and core yarn in bessoltseva spinning, providing technical result consists in the maximum release of fibers during the formation of the yarn from the influence of centrifugal forces and securing the fibers most favorable conditions for the preservation of their natural qualities.

This technical result in the formation method and single core yarn in bessoltseva spinning, which consists in the separation of the fibrous tape at the elementary fibers, the concentration on the support surface and the introduction of a rotating device for forming a fibrous sliver and twisting them sliver at the outlet of the yarn is achieved by the fact that the fibers are concentrated on a stationary support surface in the form of a complex, which is coupled to a rotating fibrous engraved tell rotational and translational movement on a fixed support surface without false twist.

The reference surface is made in the form of a hollow perforated cone with the outlet, the center of which coincides with the vertical center of the inlet manifold. Performed on the conical part of the surface of the stationary collector perforation varies in size, growing to the outlet. the binki) fan. Centered in the top of the conical perforated part of the stationary collector fibrous complex rotates directly in the manifold with a simultaneous output from it through the hole. The complex receives cylindroid shape and comes in pastoobrazna hole device for forming a sliver them. It fibrous complex, having rotational and translational motion, is compressed into a flat ribbon (Micco), which is output from penoobraznogo holes rotating fixtures twisted into yarn.

In Fig. 1 shows a device for implementing the method in longitudinal section; Fig. 2 - diagram of the device with the technological transitions spinning; Fig. 3 - technological scheme of mechanical valid twisting fibers into yarn.

Prereforming device is composed of two semi-bodies case 1 for ball bearings 2 and 3, between which is placed a ring 4 ( Fig. 1). In the inner core holes ball bearings on the desired landing through the hollow spindle mounted impeller 5 with 6 blades receiving the rotational movement of the belt 7, is pressed against the drive blocks impeller pressure rolentrando hole, which is perpendicular to the base plane of the cover is rigidly fixed cone cylindricity collector 10. His mount with cover made in the cylindrical surface 11, for example, threaded or press connection.

The centers of the inlet and outlet of the collector 10 is located on its axis of symmetry. The side surface 12 of the conical part of the header straightforward, but often need to be oval-concave and oval-convex. The transition of the side surface 12 of the conical part of the header in any form in the cylindrical part of the manifold is smooth, oval.

For lubrication of the bearing housing 1 has an opening closed by a plug 13. At the top outlet of the impeller 5 is inserted a fixed base plate 14 can be rotated along the vertical clamping plenkoobrazovatel elements 15 and 16. The mounting plate base 14 is made by screws (Fig. not shown) in the end face of the impeller blades. Blankaartia clamping elements 15 and 16 are mounted in the base 14 of the hinge. Nitropruside the hook 17 and the axis of pressure roller 8 mounted on the base 18.

The impeller 5 with 6 blades closed assembled from two components fence 19, AI. In the upper end surface of the base 19 is fixed annular electromagnet 22, the center of which coincides with the axis of the (conditional) rotation of the impeller 5 and the base plate 14.

In the assembled housing 1 of the upper and lower seals bearings rotation is not marked positions.

Prereforming the device is assembled rigidly fixed in the installation slot 23 of the slide 24. To him in the area of installation of the socket firmly attached to the duct 25. He and the slider for the required plantings slip inserted in the longitudinal hole of the housing 26, mounted on the base (Fig. not shown). The slider and the duct have a limited horizontal reciprocating movement. The slider 24 enters prereforming device in working position and displays it in the off position and places the inlet duct 25 and over the area of the possible admission of air.

To the housing 26 attached to the fence rassasivayushee drum, consisting of semi-cylinders: rear (back) 27 front 28 and a cover 29 having an outlet channel 30, which enables the directed movement of elementary fibers to the inlet manifold 10. When deciding on the AGS, the exhaust line riptionlow, with each pageviews corrugated cylinder 31 and pressure roller 32, presses the spring (Fig. not shown ) to the corrugated cylinder with the power of the R.

Line riptionlow has rotary motion from the main drive of the spinning mechanism (machine, Assembly, apparatus).

The method is as follows.

Included annular electromagnet 22 outputs from horizontal pressure blankaartia elements 15 and 16. In formed between the groove residual filamentary product 33 (single or reinforced yarn) into nitropruside the hook 17 and the Central hole of the electromagnet 22 is held through pastoobrazna the hole formed raised elements 15 and 16, and via the outlet port is introduced into the internal cavity of Conoco-cylindrophiidae collector 10, leaving some residual filamentary product 33 outside collector free.

The outlet channel 30 and the inlet manifold 10 are combined. Turns off the electromagnet 22 and included rassasivayushee drum (Fig. not shown). Of the belt 7, the impeller 5 receives rotary motion, creating blades 6 in the inner cavity of collea 30 (Fig. 1) go to the top of the conical portion 12 of the manifold 10. Residual filamentary product 33, sliding on a rotating line riptionlow, superimposed on the corrugated cylinder 31 and pressed against him with a force P of the pressure roller 32, when receiving the progressive movement.

The air flow passing from the channel 30 into the reservoir 10 with loose fibers 34, exits the manifold through the holes of the side surface 12 of the conical portion and through the vent outlet 21 receives the directed movement through the carbon monoxide chamber in obsevational ventilation (Fig. not shown).

Residual filamentary product 33, having a translational motion, due to the coupling with fibers that undergo a linear way H1+ H2translational motion (Fig. 2), enters through the hole of the conical part of the collector 10 sgruppirovalisj in her fiber in pastoobrazna the hole formed plenkoobrazovatel elements 15 and 16 with simultaneous rotational movement in a horizontal and a reciprocating movement in vertical planes.

In pastoobrazna the hole, rotating and having linear motion, is formed flat, very thin ribbon-like strip (much the LASS="ptx2">

Fiber spinning sliver 35 from its beginning torsion free ends 36 remain in the grip with a complex of fibers directly into the top of the conical part of the stationary manifold 10. In the upper complex of the fibers in the conical part of the stationary collector receives rotational and translational movement as the lower conical portion of the fibrous sliver 35. The adhesion of the fibers at the bottom (conical) portion of the sliver contribute to the centrifugal force of the rotating fibers of the upper flat part of the sliver and the air flow coming through the holes of the lateral conical surface 12 of the stationary manifold. At the same time, these centrifugal forces created by the rotating impeller of the air flow, contributing to the formation of cone-shaped part of the fibrous sliver, not have a negative impact on the last slide on the inner surface of the conical part of the fixed header.

The free lower ends of the rotating fiber conical part of the sliver during the rotation of the upcoming collector translational fibers in the clutch not come and jump up to full contact c conical part of the sliver.

In the cylindrical part to the on motion factor false twist there.

Fibrous sliver is twisted into yarn after turning off the electromagnet 22 returning to the horizontal position of the rotating clamping plenkoobrazovatel elements 15 and 16 (Fig.3) at the point 36 is the beginning of the torsion located in close proximity (0.5 - 1.0 mm) to the upper plane of the clamping elements 15 and 16.

Twisted flat ribbon-like strip (sliver) 35 in the yarn 37 on the site, located between the start point twist 36 and point compression force P between reptilandia 31 and pressure roller 32, that is, on a plot of H4. In violation of the linearity prereforming plot H4the most intensive area of przeformatowanie is a plot of H5. This caused some tension twisted sliver on a plot of H4due to pressing it with a certain force to nitroprusside the hook.

The rate of production of the fibrous sliver 35 and twisted (formed) yarn 37 is equal to the linear velocity of the exhaust pairs 31 and 32. The twist value of the obtained yarn (twists per 1 m ) is directly proportional to the number of revolutions of the impeller and inversely proportional to the rate of release.

Elimination of breakage is performed on the sequence of the start of the spinning process.

The peculiarity of the method in the following.

Serdechnikov product (Fig. not shown) is connected to the residual filamentary product 33 (Fig. 1) and through the upper nitroprusside of the hook 17 and the bottom (Fig. not shown) is conducted through the centers of the electromagnet 22, the base plate 14, a stationary collector 10, is introduced into the channel 30 and the lower nitroprusside hook (Fig. not shown), while being continuously wound on the coil (Fig. not shown). Filamentary product 33 by rotation of the coil after serdechnovym product several wound on it. In the future, the spinning process is similar to the process of spinning single yarn.

When the spun core yarn instead of the casing 29 is a casing with razoobrazny insert.

To eliminate breakage activates the electromagnet 22 by filling studs reinforced thread from the exhaust of the pair is pulled through prereforming device, the channel 30 of the casing 29. It serdechnikov product, such as copper wire, glued ( SU 220103 A, 26.08.68). Glued serdechnikov product and little time armirovannoj the camping electromagnet 22. Next, the sequence of the elimination of breakage of the same sequence eliminate breakage during the spinning single yarn.

Method of forming single and core yarn in bessoltseva spinning, which consists in the separation of the fibrous tape at the elementary fibers, the concentration on the support surface and the introduction of a rotating device for forming a fibrous sliver and twisting them sliver output from it into yarn, characterized in that the fibers are concentrated on a stationary support surface in the form of a complex, which is coupled to a rotating fibrous engraved tell rotational and translational movement on a fixed support surface without the false twist.
