| Zusammenfassung: | The device (10) has a top thread clamping unit (26) for catching and clamping a thread end region (TA) of a top thread (T), and a drive unit (27) for driving the clamping unit. A thread wiper unit wipes off a section of the thread end region under a clamped part of the thread end region in a starting path of a loop of the top thread when the thread end region is caught and clamped by the clamping unit. The wiper unit has a thread wiper body movable in a horizontal direction and held and pre-stressed by a pre-stressing unit. |
