ABSTRACT:
A regulating device for actuating the regulating element of the speed-changing unit of a warp-beam let-off motion as a function of the position of a lever of the balance for measuring the tension of warp threads. A jamming member is engaged over a bar which is driven in reciprocating motion by an eccentric. The jamming member is capable of selective sliding along the bar or jamming against said bar according to the orientation given to the jamming member by a rod attached to the balance lever. The energy required for regulating the speed-changing unit is supplied by a shaft which is driven by the main motor of the loom and drives the bar in reciprocating motion.
