Abstract: A yarn collecting bobbin comprising an elongated, tapered tube having a frustro-conical skirt affixed thereto is disclosed. The skirt encircles generally the base section of the bobbin, with a relatively short extension from the tube projecting beyond the lower end of the skirt. The skirt is firmly secured to the tube by any of several different techniques and is notched so as to entrain a yarn end adjacent thereto and commence winding of the yarn on the bobbin.

Abstract: A ''''balloon'''' is formed by an advancing yarn and is deflected to cause the yarn to be severed. In one environment, a tender patrols spinning stations of a spinning machine and automatically stops to service any of the stations requiring servicing which might occur, for example, because a bobbin being wound at the station is full. Upon stopping at a station, an operating assembly on the tender causes a yarn guide of the station to be retracted, and also causes a deflecting unit on the tender to deflect normal ballooning of the advancing yarn. This action, in turn, slows or stops a ring traveler which normally carries the advancing yarn about the bobbin, thus increasing the advancing speed of yarn while its withdrawal rate remains constant, and thereby severing the strand. In another environment, a supply bobbin is stationary and over-end withdrawal of the unwinding end at a generally constant speed causes the yarn to balloon transversely of the bobbin which facilitates faster unwinding. The balloon is deflected so that the yarn cannot be withdrawn as rapidly from the supply bobbin resulting in severing of the yarn.

Abstract translation: “气球”由前进纱线形成并被偏转以使纱线断裂。 在一个环境中，对纺纱机进行招标巡逻，并自动停止服务任何可能发生维修的车站，例如因为在车站处缠绕的筒管已满。 在车站停车时，招标上的操作组件使车站的导纱器缩回，并且还使得招标上的偏转单元偏转前进纱线的正常气胀。 这个动作反过来会减慢或停止通常在纱管周围携带推进纱线的环形旅行者，从而提高纱线的前进速度，同时其退出速率保持恒定，从而切断纱线。 在另一个环境中，供应线轴是静止的，并且展开端的大体恒定速度的过端退出导致纱线横向于线轴，从而有利于更快地展开。 气球被偏转，使得纱线不能从供给筒管中迅速地抽出，从而导致纱线的断裂。
