Abstract
An apparatus for tensioning warp threads in a weaving machine having a rotatably mounted carrier beam (5) which exerts strain on a tensioning roll (10) acting on the warp threads (15). A pre-stressed torsion spring (16) is arranged inside the carrier beam (5) and via its torque, presses the tensioning roll (10) against the warp threads (15). The apparatus can sense the torsional moments of the torsion spring (16).
