Device and method for producing a rope lap. The device includes a rope-forming device structured and arranged to combine threads drawn off from a plurality of thread bobbins in a creel to form a rope, and a bobbin carriage having a warp beam with side disks and a traversing device with a rope guide arranged adjacent to the warp beam. The rope is guided through the rope guided.

The prevailing tension in an elongate strand, such as a textile yarn, is instantaneously measured, even at very low levels of tension and at fine incremental changes in tension, by a tension measuring apparatus utilizing a pair of fixed contact arms spaced from one another to define a strand contact line therebetween and an intermediate cantilevered sensing arm disposed at an equal spacing from each fixed contact arm and at a lateral spacing from the stand contact line. The fixed contact arms and the sensing arm are contacted with the strand simultaneously at the same common lateral side of the strand to cause the strand to deflect from the strand contact line at equivalent strand break angles between the respective strand contact points on the fixed contact arms and on the sensing arm. An electrically powered strain gauge, preferably incorporating a Wheatstone bridge circuit, is associated with the sensing arm to generate a continuous electrical output signal varying instantaneously in proportion to the corresponding instantaneous tension prevailing in the strand while in contact with the fixed contact arms and the sensing arm. In one embodiment, the measuring apparatus is contained within a portable hand-held housing for manual placement in contact with a strand whose tension is to be measured, with an auxiliary hand-held housing supplying electrical power to the strain gauge and containing a microprocessor to compute a quantitative tension value from the output signal received from the strain gauge.
摘要:
Method and device for treating a warp thread sheet. The method includes drawing off a plurality of warp threads from a creel, winding the warp threads, after being drawn off from the creel, onto a warp beam, combining the drawn off threads to form a rope, and treating the rope with a treatment agent. The warp threads are unwound from the warp beam before the treating of the rope, and the rope is formed between the unwinding from the warp beam and the treating.

Device and method for treatment of a warp thread sheet and take-off frame for treatment of a warp thread sheet. The device includes a take-off frame including at least one warp beam and first and second outlets, a treatment device arranged after the take-off frame, and a warp thread pick-up device. Threads drawn off from the warp beam that are arranged next to one another transversely to their longitudinal direction are guided to the first outlet, and threads drawn off from the warp beam combined to form of a rope are guided to the second outlet.
