ABSTRACT:
A device for automatically controlling the warp yarn tension in a loom in which the fixed deviation bar for the fabric under formation is supported only at its ends. A deformation sensor, moreover, is directly supported on the deviation bar. The deformation sensor is electrically connected to a comparator to which an adjustable set-value unit is also connected, the output of the comparator being used to drive the geared motor of the warp yarn feed beam to control the warp yarn tension.
