NEEDLE DRUM OF ROTOR SPINNING MACHINE

摘要

FIELD: textiles, paper. ^ SUBSTANCE: needle drum of rotor spinning machine comprises a cylindrical shell with rows of needles of the card clothing and axis of rotation. Between the rows of needles on the cylindrical shell of the drum parallel to its longitudinal axis the benches are made with a cross section having the shape of a right angle of right-angled triangle, the short leg of which is directed along the radius of the drum, and turned toward his rotation. ^ EFFECT: invention enables to improve the combing capacity of the drum and to improve the output of fibers in the turbine of the spinning chamber of rotor spinning machine. ^ 2 dwg
