Abstract
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 guide—while maintaining its normal traverse speed at all times—to 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.
