DRAWING TOOL OF SPINNING MACHINE Russian patent published in 2011 - IPC D01H5/22 

FIELD: textile, paper.

SUBSTANCE: drawing tool of spinning machine comprises several drawing pairs, including cylinders, press rollers and facility for adjustment of flow arc with an outlet cylinder thread. The facility to adjust the flow arc with the outlet cylinder thread is arranged in the form of contacting roller and cylinder of equal diameters, installed with the possibility of reciprocal movement in plane perpendicular to axes of drawing pairs, at the same time the roller and the cylinder of the facility for adjustment of the flow arc with the outlet cylinder thread are installed with the possibility to envelop the cylinder with yarn, and a groove is provided on the roller opposite to the cylinder groove. To provide a low friction coefficient, the surface of the roller and cylinder grooves is made of fluoroplastic.

EFFECT: invention makes it possible to increase strength and to reduce breaking of the produced yarn by reduction of flow arc with the outlet cylinder thread, which helps to spread twisting into zone of thread pressing formed by the front drawing pair.
