<p>1. Modulator mechanims for controlling rotating dobbies, of the type comprising a fixed cam (11) for actuating at least one follower roller (12, 13) borne by a rotating support (14, 15) which is connected to the shaft of the loom (1) to move continuously around the said cam and which is associated with means adapted to transmis its oscillatory movement to the main shaft of the dobby (4) to impart thereto an intermittent movement of rotation, characterized in that, with a view to avoiding any toothed member risking introducing an effect of discontinuity and of angular vibration, the transmission means comprise at least one block (16) which moves inside a slide (14a, 15a) made in the roller-bearing support (14, 15) and which is provided with at least one boss (16a) for the articulation of a crank pin (17) fast with the main shaft of the dobby (4).</p> |
