SU279383A1 - Device for endless spinning - Google Patents

Description

The invention relates to the textile industry and can be used in spinless spinning machines operating on the principle of using air or water vortex energy.

A device for endless spinning is known, having its body with a channel for feeding fibers and a spinning chamber with a channel for supplying compressed air forming a whirlwind twisting the fibers into the yarn.

However, these devices are distinguished by the fact that not all of the disconnected fibers fed into the spinning chamber are injected into the yarn, since some of the fibers that are not firmly adhering to the bow are pulled off by a powerful stream of compressed air and are discarded. Therefore, the question of reducing the number of unwireable fibers is of paramount importance.

The purpose of the invention is to increase the yield of yarn. For this, the device body is made detachable, its parts are connected by means of spring-loaded rods, and a spinning chamber is located in one of the parts.

The drawing shows the proposed device, a General view.

It includes an aerodynamic spin chamber 1 with channel 2 for outputting the flagella 3 being formed and with the feed

tangentially directed tube 4, aerodynamic torsion body (vortex nozzle) 5 with threading channel 6 and a mechanism for lowering and lifting torsional

an organ consisting of guide columns 7 and przzhin 8.

The device works as follows.

Vortex torsion body 5 is

is an independent node that is not related to

camera 1.

The intensely swirled air vortex coming out of the organ 5, acting on the twig 3 weakly twisted in chamber 1, gives it the necessary twist and the yarn 9 is ready to go through channel 6 and wind on a reel (not shown).

With this arrangement of the torsional body 5, compressed air supplied to the torsional body for organization at the exit from it.

an intense air vortex, not into the spinning chamber, as in the known device, but into the atmosphere, the longitudinal chamber. This ensures a reduction in the number of unwireable fibers as compared with that provided with the discharge of compressed air through the spinning chamber, since under these conditions compressed air breaks down the insufficiently firmly accustomed to the urine in the proposed device and eliminates the effect of blocking the feed channel with a jet of compressed air coming out of the torsional organ, which ensures the uniformity of the supply of scattered fibers into the spinning chamber.

For the convenience of the charging process, there is a device that allows the body 5 to move along the axis of the chamber 1.

Their yoKeT is, for example, a device consisting of guide columns 7, on which a torsion body 5 is mounted with a sliding fit, and springs 8 for returning the body 5 to its original position after refueling.
