  • Device for winding a piece of fabric under constant tension, especially for a weaving loom
    Patent number: 4445545
    Abstract: The fabric produced by a loom is wound on a drum which is driven in rotation from the fabric take-up roller by means of a friction coupling, the friction being adjustable by means of a regulating nut. A tensioning roller which is capable of displacement under the action of the tension of the fabric actuates a pawl by means of a mechanism comprising two elbowed levers and a connecting-rod. The pawl is capable of engaging in teeth carried by the regulating nut in order to lock the nut in position and tighten-up the friction coupling when the tension of the fabric decreases.
