Patent number: 6119733Abstract: A weft thread clamp for a weft thread presenting lever is positively actuated to selectively open or close the clamp and thereby release or hold the weft thread respectively. To achieve this, a second clamp element is movable or deflectable relative to a first clamp element of the clamp. The movable second clamp element may be directly embodied as an actuator, or may be driven by an actuating motion provided by an actuator located remotely from the clamp on the lever. In the latter case, a motion transmission arrangement such as a sheathed push-pull cable or a rod linkage operatively connects the actuator to the movable second clamp element. The actuator may be a piezoelectric, electromagnetic, hybrid pneumatic-electric, or hybrid hydraulic-electric device, or an electric motor. The loom control unit is connected to the actuator for providing control signals thereto.Type: GrantFiled: November 16, 1999Date of Patent: September 19, 2000Assignee: Lindauer Dornier Gesellschaft mbHInventors: Stephan Arndt, Horst Haeussler, Kurt Motz, Peter Schiller
