Abstract

The invention relates to an improved arrangement of a back rest, and to the corresponding loom, of the type comprising a back rest (C) - which carries the warp yarns (T) coming from a warp beam - mounted oscillating on a suspension mechanism and further provided with a sensor detecting the average tension of the warp yarns carried thereon, wherein said sensor is a torsional load cell located between said back rest (C) and the suspension mechanism.
