Abstract

Control system in the draws of the warp threads, in the looms of undulating shedding and impulsion of the insertion-milling bobbins, characterized by comprising a system of inserting-bathing bobbin operated inside the shed, together with the movement of the warp yarns, the tightening or "twisting of the yarn being carried out by the walls of the carrier bobbin of the weft length, comprising a roller that counteracts the antagonistic pressure exerted by the warp threads in the peripheral zone of the bobbin walls., the bobbin being provided with compensating elements of weft yarn length to neutralize the voltage variations, the bobbin sounder being designed so that it can not become dirty and its movement is carried out by means of the teeth of the comb against its follower roller, for which, the teeth of the comb have a reciprocating movement following the direction of the warp threads, being guided these threads parallel to the angle of the puffs until their vertex by the same teeth of the comb, these teeth being supported and guided by a bed of sheets of variable distances, having the levers that drive the healds sent in their two movements by cams rolled, serving each articulation of the heddle layer with the lever, to send two or more warp threads, the control cams of the graft bobbins, all of them being rolled and mounted on a chain apart from the support chain of the control cams the healds, existing an electrical control that detects the possible lag of any inserter.
