CHANGE OF PHYSICAL AND MECHANICAL INDICATORS OF YARN DEPENDING ON THE DESIGN OF THE SAMPLING DRUM

Increasing the spinning speed of pneumatic spinning machines is a promising way to improve its performance. Welding and wrapping are carried out through separate working bodies, which is a prerequisite for the yarn forming process. The proposed device allows for uniform disintegration of fiber material and increased efficiency. In this article, a third-type drum between two-stroke gear and a flexible voltage drum was used to improve the performance of the discrete drum on pneumo-mechanical spinning machines and to efficiently absorb the amount of dust in the fiber. For this purpose, a disassembled drum of the pneumo-mechanical spinning machine was mounted with a metal-clad gear set. At the same time, the discrete drum cylinder was made in the form of an external screwdriver mounted on the base of a flexible plug. The inner surface of the gear heads and the outside of the helmet are made in a curved shape. The height of the articulated head teeth is about 0.4 works 0.6 mm. The difference between the diameter of the saw and the diameter of the drum must meet the condition D-d = 8-1.2 mm. This means the diameter of the drum along the edges of the arrows, and d - the diameter of the drum in the middle of the arrows, while the flexible and outer valves are connected to each other. The results show that yarn made in two-winged machines with a flexible vacuum is much longer than yarn in the form of single-lined and two-wire rolls, which is so significant in the technology of yarn processing that it stretches to a certain value, which then creates tension in its effects. The 5% extension of the two-stranded headlamps is proved to be 9.19 sN / tex and 8.6 gs / tex in single-roll packages and 8.1 sN/tex in two-wheel drive machines.
