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.
A weft thread clamping and presenting arrangement comprising a thread clamp including a first clamp element and a second clamp element that is connected to said first clamp element and that is deflectable relative to said first clamp element, wherein said second clamp element comprises a piezoelectric actuator that forms at least a part of said second clamp element and that is arranged and adapted to deflect said second clamp element relative to said first clamp element.
A weft thread clamping and presenting arrangement comprising:
A weft thread clamping and presenting arrangement comprising:
In a weft thread presenting and clamping apparatus for presenting a selected weft thread to a weft insertion gripper of a gripper loom, including a plurality of weft thread presenting levers arranged to be pivotable about a pivot axis and shiftable along said pivot axis to move a selected one of said levers into a thread presentation reference plane, a plurality of weft thread clamps that are respectively mounted on free ends of said presenting levers and that each respectively comprise first and second clamp elements adapted and arranged to clampingly hold a weft thread therebetween, and a computerized control unit that is adapted to store and execute a control program and thereby control a pivoting and shifting of said levers with respect to said pivot axis,
