ABSTRACT:
In a mechanism for controlling the motion of the weft carrying grippers in looms, the inlet movement is the rectilinear reciprocating motion of the small end of the final connecting rod of a linkage operated by the main shaft of the loom, and the outlet movement is the rotary reciprocating motion of a gearwheel controlling the straps for advancement of the grippers. The mechanism comprises a screw and a slider through which said screw passes, one of said elements being moved along a fixed rectilinear path by said connecting rod small end, while the other element is caused to rotate about its own axis, parallel to said path, to cause the rotation of said gearwheel. The mechanism comprises, further, rolling means, carried by said slider and being in engagement with the threading of said screw, to cause the rotation of one of said elements, as a function of the translation of the other element.
