摘要： The leading end of a weft thread exiting from a weft insertion channel in an air jet weaving loom is monitored by a weft stop motion positioned in a weft stretching channel directly downstream, as viewed in the weft motion direction, of an exit of the weft insertion channel. The weft stop motion is either an additional weft stop motion monitor or it is the first weft stop motion device repositioned from a location at the exit of the weft insertion channel to a location in the weft stretching channel. In such a position in the weft stretching channel faults or deformations such as a loop in the leading end section of the weft thread are readily or positively detected for generating a respective loom control signal.

摘要： 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.

摘要： A method and a device limit the normal shed opening angle (&agr;) of warp threads in an open loom shed, to a smaller limited shed opening angle (&agr;1) that applies to the selvedge warp threads over a selvedge laying-in width at the edge of the fabric. The limited shed opening angle (&agr;1) is smaller than the normal shed opening angle (&agr;) and is selected to provide optimal positioning and binding-in of the free thread end of a beat-up weft thread that is guided back and laid or tucked into the next open shed to form a high quality laid-in selvedge. The shed opening limit device includes two thread-constraining prongs that extend perpendicularly to the direction of the warp threads at least along the desired laid-in depth of the selvedge. The selvedge warp threads are guided and constrained between the prongs so that the extent of shed opening of the selvedge warp threads is limited to the limited angle (&agr;1).

摘要： A weaving machine with pneumatic weft insertion is provided which includes a fixed reed filler at an output end of a reed when it is in a weft insertion position. A catch salvage forming device is disposed at an output end of the fixed reed filler when the reed is in the weft insertion position and serves to keep the inserted weft stretched during movements of the reed between a weft insertion and a beating up position. In order to shorten the overall length of the assembly, a weft stop motion for detecting the insertion of the weft is located on the fixed reed filler.
