Abstract

A slow-gear selection and pick-finding clutch device in a weaving loom and method therefor is disclosed, of the type comprising a stator (1) integral with the loom and a flange (2) fixed to a driven shaft, equipped with opposing, flat bevelled toothing, between which a disc (3) is located integral with the loom main shaft, provided with corresponding flat bevelled toothing, translatable from a coupling position to said stator (1) to a coupling position to said flange (2), said disc being displaceable under the action of a magnetic force developed by a solenoid (E) integral with said stator (1), at the toothing (1a) of said stator (1) a flat circumferential surface (1a') being provided, so as to define, together with a flattened area (3a') in the corresponding toothing (3a) of said disc (3), at least a pair of flat coupling surfaces (1a', 3a'') intended to come into contact when the solenoid (E) is energised. <IMAGE>
