Abstract (en)

[origin: WO2022112024A1] In a method for carrying out an automatic can change process at a spinning station (2) of a spinning machine (1) by means of a movable can changer (14), a sliver (4) is fed from a spinning can (3), which is positioned below the spinning station (2), to the spinning station (2) in a feed direction (LR) by means of a supply device (5) of the spinning station (2). In order to carry out the can change process, the sliver (4) is severed. The sliver (4) is clamped by means of a clamp (10, 18) of the can changer (14). After the clamping, the sliver (4) is severed, and after the severing, the supply device (5) is driven counter to the feed direction (LR), and a residual sliver (21) remaining at the spinning station (2) is fed back and ejected from the spinning station (2) by means of the supply device (5). A corresponding spinning machine (1) has at least one control unit (16) which is designed to carry out the method. Furthermore, a movable can changer (14) has a fixed clamp (18) for clamping a sliver (4) on the spinning can (3).
