Abstract: A take-up spindle carries axially spaced chucks each having a body carrying a plurality of chuck members for gripping the inner face of a hollow take-up core. Each chuck has a plurality of concentric springs which urge an actuator into a gripping position to cam the chuck members into gripping engagement with the core. Release mechanism concurrently urges the actuators of all the chucks to a released position whereupon the chuck members of each chuck are urged to a retracted position by an annular spring received in notches in generally radial faces of the respective chuck members. The chuck members are small and light weight to effectively eliminate resultant centrifugal force deforming the core, and are mounted to maintain a normal gripping force on the core although the core may tend to move axially of the spindle and chucks.

Abstract translation: 卷取轴承带轴向隔开的卡盘，每个卡盘具有承载多个卡盘构件的主体，用于夹持空心卷取芯的内表面。 每个卡盘具有多个同心弹簧，其将致动器推动到夹紧位置，以将卡盘构件凸轮与卡盘夹紧接合。 释放机构同时将所有卡盘的致动器推动到释放位置，从而每个卡盘的卡盘构件通过环形弹簧被推压到缩回位置，环形弹簧被接收在相应卡盘构件的大致径向面上的凹口中。 卡盘构件体积小，重量轻，有效地消除了使芯体产生的离心力变形，并且被安装成在芯上保持正常的夹紧力，尽管芯可能倾向于主轴和卡盘的轴向移动。

Abstract: A take-up machine having a rotating spindle on which a tube is releasably clamped for winding of a strand of yarn onto the tube to form a yarn package. The machine automatically threads the strand of yarn onto the spindle to start winding of the yarn onto the tube and, if desired, first winds a tailing end about an end of the tube, and then winds a body of yarn on the tube to form the yarn package. A variable speed spindle drive is automatically operated at a manually pre-set constant speed during thread-up and immediately upon thread-up is switched to a speed different from the constant pre-set speed and conventional control of the winding speed.
