FIELD: textiles, paper.

SUBSTANCE: sizing machine comprises a rack with warping shafts, a pulling device, a glue box, a dryer, leases, a spacing reed and an outlet device. According to the invention, between the pulling device and the warping shafts parallel to the latter a belt conveyor is mounted, with the substrate of segment section located inside, which is in contact with the upper branch of the conveyor belt, and on the conveyor belt on its both sides outside the filling working with the pressing cones are located.

Known sizing machine, containing a rack with warping shafts, drive and guide rollers for winder main thread with warping rollers, adhesive bath with plunging shaft, dryer drums, emulsifying device, rates, producing the device. [Gordeev V.A., Volkov PV Weaving: a Textbook for high schools. - 4th ed., Rev. and ext. - M: Light and food industries, 1984. - 488 S., s].

The prototype was taken sizing machine [the Patent for useful model №104186 RF IPC D06B 3/06. Slashing machine. Postnikov A.V. and other applicant and patentee of the GOU VPO "IV. Educat. Textile Academy"

No. 20101148269/12; Appl. 25.11.2010; publ. 10.05.2011, bull. No. 13. - 2 S.: ill]containing the drive shaft with the idlers, the adhesive bath with plunging shaft, dryer drums, vibrating the device.

The disadvantage of these machines is that when running at speeds of over 50 m/min there is a raised hood main thread, which negatively affects their physical properties, are prerequisites to breakage and puffs at fabrics on looms.

For high hood main threads affected by the fact that mainly slimtouch single yarn. In the process according to the cooking to the dressing she is fast and warping. These technological transitions the strength of the main threads is reduced. The main reasons for the decrease in strength is that the threads in the process is exposed to tensile stress and promoted by the forces of elasticity, directed opposite to the direction of the twist.

Moving thread to the drive shaft and the tension when winding with warping of the shafts causes deformation of the torsion. Modified twist of the threads in this case will be defined as

KN=KP-KTR·Cos2β,

where KN is the resulting twist yarn, steeps/m;

KP - twist yarn, hills/m;

B - torsion angle, deg.

The twist of the thread in the process of unwinding the study area will be reduced due to friction on the shaft:

Ktp=πDinninπdnVnη,

where Dinand nin- the diameter in mm, and the frequency of the guide shaft, min-1;

dn- estimated diameter thread mm;

Vn- the speed of movement of the thread through the guide shaft, m/min;

η - efficiency of friction on the shaft.

The technical result of the claimed invention is to reduce the hairiness and ysenia strength characteristics of the yarn.

This technical result is achieved by the sizing machine containing a rack with warping shafts, drive device, the adhesive bath, a drying device, rates and exhaust device according to the invention, between the drive device and warping shafts parallel to the last installed the belt conveyor is placed inside the substrate segment section in contact with the upper branch of the conveyor belt and the conveyor belt from both sides outside the filling of the working width of the machine are clamping cones.

In the contact process main thread with the surface of the conveyor belt is additional tightening depending on the strength and angle of contact of the yarn with the surface of the moving tape. This tightening strengthens inter-fiber connection on the surface of the yarn that reduces its hairiness and, in the process of impregnation dressing, followed by drying, prevents the influence of tensile forces, thereby lowering the hood.

Figure 1 shows the process diagram of the inventive sizing machine; figure 2 shows the belt conveyor and clamping cones (top view); figure 3 shows the interaction between the conveyor belt with the main thread.

The inventive sizing machine contains a rack 1 from warping rollers, the staking device is TWT 2, between which parallel them installed conveyor belt 3 is placed inside the substrate 4 segment section.

In contact with the upper branch of the conveyor belt 3 from both sides outside the filling of the working width of the machine in areas of the lead 5 and the follower 6 pulleys are clamping cones 7. For the staking device 2 are positioned successively adhesive tub 8, a drying device 9, the price of 10, the separator row 11, the exhaust device 12 and weaving beam 13. Drive pulley 5 of the conveyor receives motion from the actuator 14.

Sizing machine operates as follows.

The main thread 15 is retracted from warping shafts, located on the rack 1, under the action of the drive device 2. When the motion they are in contact with the upper branch of the conveyor belt 3. To prevent sagging of the upper branch from the pressure of the main threads under it inside the conveyor 3 is posted substrate 4 segment section.

For a snug fit the edges of the ribbon to the substrate is provided by pressure guides cones 7. They are located in areas of the lead 5 and the follower 6 pulleys and acting from above on the edge of the working branch of the tape and press them to the surface of the substrate 4.

Setting and form of the substrate 4 eliminates the contact of the threads 15 with edges (edges) of the tape, thereby eliminating mechanical damage Nita from the hard uneven edges of the tape, that allows smooth effects conveyor belt 3 of the thread 15. (figure 1, figure 2). The direction of movement of the working branch of the conveyor belt is set by the actuator 14 and must comply with the direction given twist fibrous part of the canvas.

Due to the pressing force to the surface of a moving conveyor belt, and the contact angle is an active twisting strands around its axis (figure 3). Tightening spreads over the whole length of the plot threads from the separation point from the last warping of the shaft to the point of contact with the guide roller drive device 2.

After rounding the staking device 2 main threads 15 are received in the adhesive tub 8 for impregnation dressing, dried drying or hot air device 9, are separated by price 10 in the horizontal direction.

In the future, the threads pass through the separator row 11 and outlet 12 with subsequent uniform unfolding throughout the working width of the weaving beam 13.

The proposed solution is slashing machine allows you to increase the number of secondary turns for 7-9% of the nominal twist, to reduce the hairiness, to strengthen inter-fiber connections, to prevent the loss of twist from the strain of bending and friction on the guide surface and to maintain the strength of the threads.

The concentrate is oval machine, containing rack with warping shafts, drive device, the adhesive bath, a drying device, rates, dividing the row and the discharge device, characterized in that between the drive device and warping shafts parallel to the last installed the belt conveyor is placed inside the substrate segment section in contact with the upper branch of the conveyor belt and the conveyor belt from both sides outside the filling of the working width are clamping cones.
