Abstract

1. A method of producing a reinforced yarn, through which a stream of loosened fibers is fed onto a flat surface of a rotating disk of a torsion-forming organ, is applied to the core yarn of a fiber by passing it through a stream of fibers. a sliver is formed from the fibers, followed by passing it through the axial hole of the disk, and the core thread is connected to the sliver under the disk and then twisted, characterized in that, in order to reduce the amount of fibers carried to the carbon fiber and to improve the quality of the reinforced thread through the flow of fibers and when connected to a sliver, it is rotated relative to the axis of the disk with the formation of cores of cylinders with vertices located on the axis of the disk with two opposite along the axis of the cylinders; The shaping of the sliver is performed by subjecting the fibers to an air stream directed along the axis of the disk towards the removal of the reinforced filament.

The invention relates to textile industry, namely to ringless spinning, and can be used on rotary spun masks to obtain reinforced yarns from pure cotton or wool fibers in pure form or their mixture with chemical fibers.

The aim of the inventions is to reduce the amount of fibers carried away into the waste and improve the quality of the reinforced yarn.

FIG. 1 shows the general scheme of the device; in FIG. 2, a torsional-forming organ,.

A device for obtaining a reinforced yarn 1 comprises means for separating and feeding fibers 2 through a fiber via a forward channel. 3 to a torsion-forming organ, having a feed cylinder 4 with spring I 5 fed to it, feeding table 6 and combing roller. 7, the torsional-forming body has a drive disk 8 horizontally mounted below Channel 3, having protrusions 10 on the upper flat surface 9 to form a collecting surface and fixed on the lower flat surface of the blade 11 to form a cavity 13 between the disk and the sleeve 12 located under it,

In the wall of the fiber-guiding channel 3 on the axis of the disk, the guide 14 of the core yarn 15 is installed, made from the package 16. The disk 8 has an axial channel 17 for the passage of the sliver 18,

communicating with the cavity 13, and a through hole 19 for the passage of the core yarn, located with a radial displacement relative to the axial channel 17..

The method for producing a reinforced yarn is carried out as follows.

The fibrous tape 20 from the pelvis 2.1 is fed by the roller 22 to the funnel 23, in which it is straightened and given the required position before feeding to the comb roller 7. The roller 7 separates the tape into individual fibers and flows them through the channel 3 onto a flat surface 9 of a rotating disk . A core thread 15 is rotated through a stream of fibers, which is rotated relative to the disk axis due to its passage through its opening 19 to form two upper and lower sides of the disk opposite to the axis of the disk with peaks located on the disk axis in directional 14 and clamp pairs of lead rollers 24. The upper balloon of the thread t high-frequency intersects the stream of fibers, as a result of which a significant part of them is applied to the core thread and wrapped in fibers before the surface 9 of the disc is reached. The remaining fibers are fed to the disk, where they form a sliver. When the disk rotates, the blades 11, working as fan blades, cause the air to flow from the disk surface through the Axial channel 17, forming a low air pressure area in the center of the disk. Thanks to this fiber focus71
