Abstract: The apparatus comprises an injector nozzle, for instance on the loom take-up roll. The injector nozzle has a plurality of air supply passages or channels opening into an extraction conduit surrounding the selvedge to be removed or extracted. The selvedge is pulled through the injector nozzle by the air coming out of the air supply passages and conducted through a tube or hose into a waste container. The injector nozzle for extracting cut-off fabric parts is especially suited for sensitive materials, e.g. glass fiber yarns. When for instance the selvedge contains severed weft thread ends of glass fiber material, the latter are particularly well protected against breakage due to the extracting injector nozzle.

Abstract: The control device contains a deflection roll extending over the entire weaving width of the weaving machine, a tensioning beam pivotable about a support beam and also extending over the entire weaving width as well as a sensing roller arranged therebetween and subject to the action of a spring for sensing a portion of the warp threads of the warp, respectively of each partial warp beam. The tensioning beam is subject to the action of a preloaded torsion-bar spring. In this manner a sensing force arises at the sensing roller which can be increased from a first value to a second value according to the position of the tensioning beam. This permits the realization of increased responsiveness of the control device.
