A system for winding wire includes a wire take-up unit and a wire cutter/grabber unit. The take-up unit includes rotatable first and second mandrel portions, and a wire directing traverse arranged to feed wire and alternately form coils on the first and second mandrel portions. The cutter/grabber unit is configured to cut the wire at a cut position between the traverse and a coil formed on the first mandrel portion and to grab a free end of the cut wire and move along a predefined cutter/grabber pathway to a hand-off position where the wire is transferred to the second mandrel portion. As the cutter/grabber is moved along the pathway from the cut to the hand-off position, a length of wire between the traverse and the free end of the wire does not decrease, and that length of wire is longer at the hand-off position than at the cut position.

The present invention is a part of a yarn transfer system used for transferring yarn from a full bobbin to an empty bobbin typically fitted on a winder frame. The invention broadly comprises a yarn traverse device used in transferring a continuously arriving yarn onto an empty bobbin for commencing of winding process during bobbin changeover process in automatic turret winder without any stoppage. This is achieved with the provision of an actuation device that facilitates axial movement of the yarn traverse device. In the present invention, during the bobbin changeover operation, the yarn traverse device is moved axially through the actuation device and allows the traverse guidewhile maintaining its normal traverse speed at all timesto move beyond the normal yarn winding zone such that the advancing yarn is within the reach of the yarn grasping device of the ready-to-be-wound empty bobbin. After the yarn transfer is completed, the traverse device moves back to the normal winding zone.

Apparatus and methods for winding flexible material include a rotatable plate assembly rotatably driven by a first rotary shaft, the assembly supporting second and third rotary shafts with corresponding first and second mandrel parts mounted thereon. The first and second mandrel parts each form at least part of a winding spool. The second and third rotary shafts have rotational axes that are parallel to one another and parallel to, but laterally offset from, the rotational axis of the first rotary shaft. The rotation of the plate assembly is coordinated with counter rotation of the first and second mandrel parts. In embodiments, such coordinated rotation occurs during transition operations performed between winding operations that employ the first and second mandrel parts in an ordered sequence one after the other. The flexible material can be cable, wire, tubing, hose, rope, or other filamentary material. Other aspects are described and claimed.
