  • Publication number: 20030173447
    Abstract: The present invention relates to a method for operating a workstation of a cheese-producing textile machine, having a pivotably seated creel for rotatably maintaining a cheese, a bobbin drive arranged on the creel, a support roller, which during the winding operation is driven by the cheese by frictional contact, a separate yarn traversing arrangement, as well as a device for raising the creel in case of a yarn break or a defined cleaning cut. In accordance with the present invention it is provided that following a yarn break or a defined cleaning cut, the cheese, which is maintained in the creel and rotated in the unwinding direction by the bobbin drive, and the support roller are sufficiently spaced apart long enough for a suction nozzle to pick up a top yarn required for a subsequent yarn splicing process.

  • Patent number: 6298647
    Abstract: A yarn-connecting device for a cheese-producing textile machine having a pneumatic splicing device (22) located outside of the normal travel path of the yarn, a gripper tube (25) acted upon by suction air for manipulating yarn ends to be spliced, and a pivotable gripper tube flap (18) for closing the gripper tube mouth (27). A control crank (33) is arranged at an upper end position (II) of the gripper tube (25) for acting on the gripper tube flap (18) such that in the course of pivoting the gripper tube (25) into the position (II), the gripper tube flap (18) is lifted slightly off the gripper tube mouth (27), while the gripper tube flap (18) always closes the gripper tube mouth (27) when the gripper tube (25) is pivoted out of the position (II).
