ABSTRACT:
A loom has a winding system comprising a tension roller and a storage roller connected by means of an endless chain whereby the storage roller is driven by the tension roller with the interposition of a friction mechanism.
A follower roller, in contact with the periphery of the roll of fabric wound around the storage roller, causes a rotary cam to rotate such that the movement of the latter is linked with the variation in diameter of the roll of fabric. Bearing against the profile of the cam is one end of an oscillating lever, the other end of which acts on the friction mechanism in order to modify the driving torque of the storage roller by the chain according to the diameter of the roll of fabric.
The fabric tension regulating device can be applied to conventional looms and shuttleless looms.
