Abstract

An apparatus and method for guiding and cutting a continuously advancing yarn during a package doff in a yarn winding apparatus wherein the advancing yarn is wound on a driven bobbin tube. In this process, the yarn is guided by means of a movable yarn guide along a direction substantially parallel to the axis of the tube. Downstream of the yarn guide, a suction device is arranged, which includes a pneumatic suction inlet end and a cutter. The suction device cooperates with a transfer device, so as to cut the yarn during the package doff and receive the loose end of the advancing yarn. To facilitate a protective processing of the yarn during the package doff, during the catching, and during the winding of initial layers on a tube driven by a drive roll, the yarn guide is arranged in the path of the yarn upstream of the driven tube and the suction device downstream of the driven tube.
