ABSTRACT:
A modulator mechanism for actuating textile dobbies in looms which include a cage driven in rotation by the drive shaft of the loom and which have at least two oscillating supports provided with rollers which roll in contact with a fixed cam which is connected to the principal shaft of the dobby. Connecting rods are pivotally attached to the supports and to a web fixed to the dobby shaft so that the dobby shaft is intermittently driven in rotation as the connecting rods are oscillated by the supports.
