ABSTRACT:
A thread brake for braking a weft thread in a weaving machine includes a rigid stop and an elastically deformable blade which has a free end supported to press resiliently against the rigid stop. Thread guides are provided to guide weft threads between the rigid stop and the elastically deformable blade. The thread brake is activated when the deformable blade elastically presses against the rigid stop. When contacted by a switching device, however, the elastically deformable blade is pushed against its resilient force and removed from the rigid stop, at least in the region of the switching device, deactivating the thread brake.
