Abstract

FIELD: textile industry; equipment for production of self-twist yarn. SUBSTANCE: device has successively installed unit of vortex chambers for imparting side alternating twisting, guides of single strands and active thread connector for formation of self-twist yarn from three strands. Unit of vortex chambers has ejector feeding one untwisted strand through guide to active thread connector. EFFECT: higher efficiency. 1 dwg

Description

 The invention relates to the textile industry and relates to a device for producing self-rolled yarn.

 A device for producing self-twisted yarn in three additions is known, comprising a sequentially mounted block of vortex chambers for communicating alternating twist, single strand guides and an active thread junction for forming three strands of self-twisted yarn.

 However, in this device there is no possibility of obtaining a fleecy yarn that creates a pile effect in a knitted fabric.

 The objective of the invention is to provide a device for producing self-twisted yarn in three additions, providing a technical result, consisting in increasing the fleecy yarn, creating a pile effect in the finished product.

 This technical result in a device for producing self-twisted yarn in three additions, containing a series-mounted block of vortex chambers for message of alternating twist, guides of single strands and an active thread connector for forming three strands of self-twisted yarn, is achieved by the fact that it contains an ejector installed in the block of vortex chambers to feed one untwisted strand through the guide into the active thread connector.

 The drawing shows a General diagram of the device.

 The device comprises a series-mounted exhaust device with an exhaust pair 1, a vortex chambers block 2 for communicating alternating twist to two strands 3, single strand guides 4 and an active thread connector 5 for forming self-twisted yarn 6. In the case 7 of the vortex chambers block, an ejector 8 is installed for supplying one untwisted locks 9 through the guide 10 into the active thread connector 5.

 The device operates as follows.

 Coming out of the exhaust pair 1, three strands 3 and 9 enter the block of vortex chambers. The two extreme strands 3 pass through the vortex chambers 2, where they are informed of an alternating false twist. Strand 9 is conducted through the ejector 8 without telling her the twist. Upon exiting the vortex chamber block, all three strands 3 and 9 are compressed with compressed air through the corresponding guides 4 and 10 and connected in the active thread connecting device 5, forming self-twisted yarn 6 in three additions.

 Due to the lack of twist, strand 9 retains its loose structure in self-twisted yarn 6, which helps to increase its hairiness and create a pile effect in the finished product from it.

 This device can be installed on a spinning machine without any alterations to its pneumatic system.
