Abstract
A method and a device for initiating the rewinding process after a yarn break in single stage pot spinning. In the process, a yarn detaching device (14) is introduced into a spinning centrifuge (3) rotating a high rpm, and places a cutting edge (16, 48) against the conically wound portion (32) of a spinning cake (15) deposited on the inner wall (26) of the spinning centrifuge (3). The yarn detaching device (14) has a yarn guide device, whose yarn guide contour (17, 43) covers the cutting edge (16, 48) of the yarn detaching device (14) such that in the course of the initiation of the rewinding process lower winding layers of the conically wound portion (32) are lifted on the rewinding tube (9) and in this way dependably prevents the winding of yarn around the yarn detaching device (14) during the rewinding process.
