Abstract

The invention relates to the textile industry, to a method of continuously winding threads from a spool needle and to improve the conditions of winding threads and reduce the area required to ensure the flow of the method. A method of continuously winding yarns from a spool with working and reserve packings involves carrying out the beginning and end of the thread of the working package through the thread guide with a slot, the beginning and end of the thread starting from one side of the thread guide, carrying out the beginning of the thread of the working package in the textile machine with simultaneous positioning of the end of the thread working package in the thread guide conductor, holding the beginning of the thread of the backup package through the second thread guide with a slot, linking the beginning of the thread of the backup package to the end of the thread of the working package, storing the end of the backup package and fixing the end of the thread of the working package through the internal cavity of the working package, which is the thread conductor, and before binding the end of the thread of the working package to the start of the backup thread the packages carry out the beginning of the thread of the backup package through the internal cavity of the backup package, which is the second thread guide. 6 Il.

Description

the shelves are determined by spacer tubes 5, and the assembled section is tightened by sleeves 6. To the frame 3 in the area of the racks the thread guides 7 and nitenate residents 8 are attached. To the lower horizontal shelf of the corner 4 in the area of the center of the packings there are plate clamps 9 and 10. And the clamping force of the loop in the clamp 10 should be no higher than half the breaking load of the thread and ensure that the loop is kept in the tensioned state during the entire rewinding time.

The package 11 outside the spool box is installed on the carrier 12 of the packages, on which the elastic ring 13 and the cone 14 are pre-fixed. A removable part of the packer holder, consisting of a central tube 15 with a lock 16 on the lower end and a thread on the upper , cone 17 with unwinding ring 18, springs 19, nuts 20, tip 21. Unwinding ring 18 and tip 21 have slots 22 with bevels along the upper edge of the slot. The central tube 15 is sunk down, spring 19 is compressed by nut 20, and lock 16 (for example, rectangular) enters the opening of carrier 12 of the package corresponding to the lock configuration, and in this position lock 16 unfolds, i.e. the package 11 is fixed on the carrier 12 packages. The end and the beginning of the yarn from the package 11 is fed through the ring 18 and the tip 21 into the tube 15. The carrier 12 packages in the form assembled with the package 11 and with the 15 threads tucked into the tube is inserted into the corresponding slot of the frame 3 on the horizontal corner shelves 4. Order threading in a continuous winder pattern is indicated in FIG. 3 and 6,

The beginning of the thread from the working package is inserted into the thread guide 7, the thread resident 8, the thread guides 23 and 24 and to the textile machine. The end of the thread from the work package is inserted into the slot 22 of the unwind ring 18 and the tip 21 and is associated with the start of the thread on the backup package. Then this section of the thread is tightened, the loop is inserted into clip 10, and the end of the thread of the backup package is tightened and inserted into clip 9. The end of the thread of the working package, recessed into slot 22 and in a permanently tensioned state, is not interferes with the unwinding process.

At the end of the winding of the thread in the working package, the loop comes out of the slits 22 of the central tube 15, is pulled out from the clamp 10 and the winding process is carried out from the reserve package, which from this moment becomes working. During the winding of the yarn from the working package, the carrier of the packages with the cartridge is taken out of the slot and in its place the carrier of packages with a refilled package is inserted and the process of filling is repeated in the same order.

The tests carried out at the 6-seater stand of the spool of the rnik when rewinding chemical threads from packages weighing up to 10 kg showed that the transition from rewinding from working package to back-up takes place normally even at speeds that are 8-10 times higher than the speed when reinserting and twisting technical threads.

The use of the proposed method of continuous winding of chemical yarns avoids the formation of waste-okat during the warping, which is up to 2% in the range of technical fabrics, increases labor productivity by eliminating the need for transporting and rewinding okat, and the proposed means for providing a continuous winding method The yarns can be avoided without increasing the size of the spool core over the required additional area to install the backup package.

This increase in area on known structures of spools with continuous winding of the threads is 20-30% of the area of the spool.
