ABSTRACT:
Mechanical device disposed behind the heddle frames of a loom for increasing the weft density in cloth weave fabrics, constituted by three parallel rollers situated horizontally at the vertices of a triangle, of which the rear roller separates the two equal sets of warp yarns while the other two front rollers are located very close together and act as an outlet guide for said two equal sets of warp yarns. The three rollers are rigid at their ends with two lateral support plates which are made to reciprocate, by means of connecting rods connected eccentrically to the loom drive shaft, about a horizontal rotational axis which lies in the center plane of the shed formed by said two sets of warp yarns, and passes in proximity to the two front thread guide rollers and at an equal distance therefrom. The three rollers are connected rigidly together by intermediate support plates.
