ABSTRACT:
The position of the fell of a cloth being woven on a weaving machine is sensed with a sensor needle that can be moved into and out of the cloth at a location proximate the fell during interruption of the weaving operation. Upon insertion of the sensor needle into the cloth, it moves with the cloth and therewith measures cloth displacement while the weaving machine is at rest. The sensor needle is attached to an actuation device capable of reciprocating the needle into and out of the cloth. The sensor needle is inductively coupled to a distance sensor which measures the needle displacement and therewith the displacement of the fell. In this manner, fell displacements caused, for example, by such factors as the relaxation of the run of cloth or of the warp yarn while the weaving machine is at rest can be measured and, before weaving is restarted, the position of the cloth, and therewith of the fell, can be corrected.
