A yarn picking arrangement for an automatic yarn piecing unit and its method for automatic piecing operation in a textile machine

Abstract

The present invention relates to yarn picking arrangement (100) for an automatic yarn piecing unit in ring spinning machines, the arrangement comprising of a suction jet assembly comprises a hose (102) having a first end and a second end. The first end connected to a suction air source, and the second end has a circumferential housing (104). A driving means (106) coupled to the suction jet assembly capable of moving the suction jet assembly vertically up and down such that the circumferential housing (104) is capable of surrounding the cop (108) at the outer portion at the top of the cop (108). The suction air source during operation generates a suction pull which pulls the broken yarn end (112) anywhere in the chase length from bottom to top of the cop into the housing to enable automatic piecing operation in a textile ring spinning machine (20). An important object of the invention to provide a solution for the shortcomings of the automatic piecing unit that provide an arrangement for picking broken yarn end (112) from the spinning cop (108) to enable automatic piecing in ring spinning machines anywhere in the chase length of the cop in textile ring spinning machines.
