Abstract (en)

Device for governing and controlling a rotary dobby for actuating heddle frames in looms, comprising a control shaft (1), a disc (2) fixed in rotation on said shaft and an eccentric composed of an eccentric ring (4) keyed to the shaft, with which it can rotate relative to an external traversing body (4a) linked to the actuating bar for the frames, in which are provided a first (9, 10) and a second (13, 14) pair of levers firmly pivoted on the rotating eccentric ring (4) and adapted for cooperating radially with one another, one free end of said first and second pairs of levers being respectively adapted for engaging with the rotating disc (2) and with the traversing body (4a), the other free end (9d, 10d) of the levers of the first pair being, moreover, adapted for receiving any control action of an external programmer device (13) which causes the levers to rotate radially in a centripetal or centrifugal direction, the action and the interaction of said pairs of levers and of said programmer creating a positive command both of the engaging and of the disengaging of said levers and, simultaneously, a positive safety means which assures the correct functioning of the governing and control device. <IMAGE>
