Abstract
A drive arrangement for driving a let-off beam of a fabric weaving loom and maintaining a predetermined tension in the warp threads. The drive arrangement includes an electric motor operably connected to the let-off beam by a speed-reducing apparatus and an electrically operated clutch. A tension-sensitive device is positioned adjacent the warp threads and cooperates with same to sense the tension therein. The tension-sensitive device has a switch operably connected to said clutch wherein at a predetermined tension in the warp threads the switch closes and actuates the clutch to effect selective driving of the let-off beam in a forward direction and thereby control the tension in the warp threads.
