ABSTRACT:
Method for operating a machine intended for dyeing textile webs wherein the fabric to be dyed is passed through a dyeing bath and is wound onto a tractive roller. The instantaneous angular speed of the tractive roller is controlled during the operation of the machine and the speed regulated so as to maintain constant or substantially constant the centrifugal acceleration at the point where the fabric winds onto the tractive roller. Application is to machines of the Jig type.
