A yarn withdrawal device for open-end spinning arrangements has a yarn
withdrawal nozzle and a balloon-breaking insert which extends the axial
channel of the yarn withdrawal nozzle. The yarn withdrawal nozzle has a
curved contact surface for deflecting a yarn to be withdrawn and
simultaneously rotating the yarn in a crank-like manner, which contact
surface graduates from a front surface into the axial channel. The
balloon-breaking insert has an inner wall which is provided with raised
areas and/or recesses, with which the yarn comes into contact. The
contact surface of the yarn withdrawal nozzle is a smooth steel surface.
The raised areas and/or the recesses of the balloon breaking insert are
such that a yarn hairiness in the range of 3 mm in length is achievable.
In addition, values in relation to the spinning stability, tear
resistance and evenness can be achieved which are usual in the case of a
notched contact surface of standard yarn withdrawal nozzles without a
balloon-breaking insert.
