Abstract: A rotary chuck of a winder receives a core on which a body of yarn is wound to form a package. Upon commencing winding of the yarn it is grasped by a clamp recessed into a free end head of the rotating chuck. Immediately after the yarn has been received by the clamp it retracts a cutter guard and the strand is severed outwardly of the clamp. The yarn is wound into a spiral groove in the head to provide a tailing end of yarn of predetermined length. At a predetermined and adjustable position of the yarn in the groove the yarn is released by an adjustable yarn guide cam and is received by a yarn traversing guide which then moves the yarn to and fro axially of the core during winding of the package. When the package is full the chuck and the yarn clamp are concurrently released, and the package is telescoped off of the chuck head as the tailing end is drawn out of the spiral groove and through the core where it remains until needed.

Abstract translation: 卷绕机的旋转卡盘容纳卷绕纱线体的芯，以形成包装。 在开始卷绕纱线时，它被夹在旋转卡盘的自由端头中的夹具夹紧。 在纱线被夹子接收之后，立即缩回刀具保护装置，并且将绞线从夹具的外部切断。 纱线被缠绕在头部中的螺旋槽中，以提供具有预定长度的纱线的尾端。 在纱线在槽中的预定和可调节位置，纱线由可调节的纱线引导凸轮释放，并被纱线横动导纱器接收，纱线横动导纱器随后在包装卷绕期间使纱线沿轴向移动。 当包装满时，卡盘和纱线夹具同时释放，并且当拖尾端部从螺旋槽中拉出并通过芯部时，包装件可以从卡盘头伸出，直到需要。
