Abstract

A process, and machine for carrying out the process, for severing a fiber sliver at a textile machine includes conveying the fiber sliver by a pair calendar rollers through a sliver guiding channel of a rotary plate into a sliver can disposed below the rotary plate. The calendar rollers are stopped, and thus also the conveyance of the sliver. A severing point is defined in the sliver downstream of the calendar rollers by drafting the fiber sliver with a moveable clamping device at a desired location of the severing point. Once the fiber has been drafted at the severing point, the sliver is severed by displacement of the can from below the rotary plate.
