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.
