Device and a method for transferring advancing yarn during bobbin changeover in an automatic turret type yarn winder
09908740 · 2018-03-06 ·

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.

Systems and methods for winding wire are disclosed. A system includes a wire take-up unit having a rotating mandrel and a traverse having a wire directing device, the wire directing device arranged to cause the wire to be wound in a figure-eight configuration on the rotating mandrel to form a coil having many layers of wire. The wire directing device reciprocates along an axis parallel to the axis of rotation of the mandrel. The wire directing device also rotates along an axis perpendicular to the axis of rotation of the mandrel so that the lay-down point of the wire directing device sweeps over an arc for each throw of the traverse.
