Mechanisms for driving regulators in weaving looms

摘要

The invention relates to improvements in mechanisms for driving regulators of weaving looms. Between the shaft of the dobby and the chain pinion which drives the regulator of the loom there is interposed a differential reverser whose satellites are borne by a race axially moveable coil. The latter is moveable through the unweaving circuit so that the reverser is automatically actuated during unweaving and causes the regulator and the woven fabric to move backwards while the dobby continues to rotate in the same direction (electronic program).
