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.

An actuating valve has two relay valves connected to a compressed air source and a pneumatic cylinder with two pressure chambers. When one relay valve is actuated, one pressure chamber is pressure-loaded and the other is relieved. Two 3 / 2 port directional control valves are arranged upstream of the pneumatic cylinder. Two check valves are positioned in branch lines connecting the relay valves and the directional control valves. A control line connects the branch line to the other directional control valve, respectively. The directional control valves are moveable between a first position allowing compressed air to pass and a pressure relief position. When the relay valves are inactive, the directional control valves are in the first position and the relay valves are in a venting position for the branch lines. When one relay valve is actuated, it assumes a position allowing passage of air to the branch line connected to it.

A supply spool supplies a weft thread through an adjustable actuated thread brake and a thread tension sensor to a weft thread accumulator, from which an accumulated insertion length of the thread is provided to a weft insertion device. The tension sensor provides a measured actual thread tension signal to a control arrangement, which compares the actual tension to a selected rated tension, and, dependent on the deviation therebetween, provides a control signal to an actuator of the thread brake, so that the actual thread tension constantly corresponds to the selected rated tension. Another sensor provides a signal indicating a change from an empty spool to a full spool. Responsive thereto, the control arrangement actuates the thread brake to an adjustable starting brake setting as a coarse adjustment. Then the self-regulating fine adjustment is continued. A constant winding tension and thread accumulation length are achieved in the thread accumulator.

A yarn package support for a creel has a support arm that is pivotal about a vertical axis between a loading position and a use position. In the loading position, the package support arm is positioned to load a spool of stranded material, such as yarn or thread. In the use position, the spool and support arm are positioned so that the yarn may be feed into a weaving apparatus. The pivot arrangement permits a laborer to reposition the support arm in a single handed action.

A thread brake arrangement for use in a textile processing machine includes two brake elements with the thread running there between. An actuator, preferably a piezoelectric actuator, variably actuates one of the brake elements relative to the other to exert an adjustable braking force onto the thread. The thread exerts a reaction force in the thread running direction onto the brake elements. At least one of the brake elements is movably supported to be movable along the thread running direction, and is mechanically coupled to a force transducer that measures the reaction force, which is proportional or equal to the thread tension force. A regulating arrangement receives the measured force signal, and controls the actuator to adjust the adjustable brake element, so as to vary the applied braking force and thus regulate the arising thread tension responsive to and dependent on the measured reaction force.
