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.
In a method of pot spinning wherein a yarn is deposited on the interior wall of a rotating spinning centrifuge in the form of a spinning cake having a conically wound portion at at least one end of the spinning cake, a method for initiating rewinding of the spinning cake onto a rewinding tube after a yarn break by introducing a yarn detaching device into the spinning centrifuge and applying the yarn detaching device to the spinning cake deposited on the interior wall of the centrifuge, the applying of the yarn detaching device to the spinning cake comprising providing a drive for the yarn detaching device, placing the yarn detaching device against the conically wound portion of the spinning cake using the drive, providing a yarn guide contour on the yarn detaching device, lifting the winding layers of the spinning cake to the level of the rewinding tube using the yarn guide contour, and preventing yarn from winding around the yarn detaching device during rewinding.
In a device for pot spinning comprising a rotating spinning centrifuge having an interior wall, means for depositing a yarn thereon in the form of a spinning cake having a conically wound portion at at least one end of the spinning cake, and means for rewinding of the spinning cake onto a rewinding tube, a device for initiating rewinding of the spinning cake onto the rewinding tube after a yarn break comprising a yarn detaching device for introduction into the spinning centrifuge and application to the spinning cake deposited on the interior wall of the centrifuge, the yarn detaching device including a drive for placing the yarn detaching device against the conically wound portion of the spinning cake, a cutting edge for contacting the conically wound portion of the spinning cake, and a yarn guide contour for lifting winding layers of the spinning cake to the level of the rewinding tube and preventing winding of yarn around the yarn detaching device, the yarn guide contour being adapted for covering the cutting edge in an axial direction.
