ABSTRACT:
A machine for manufacturing triaxial fabrics, primarily of the type disclosed and claimed in U.S. Pat. No. Re. 28,155, comprises a vertically oriented warp yarn supply means based upon a horizontally disposed rotating creel, on which is preferably mounted a plurality of beams each supplying a plurality of warp yarn ends. Guide holders travelling on a cam-shaped track compensate for warp yarn path length changes so as to maintain path lengths from creel to weaving means relatively constant independent of angular position of an individual warp yarn in the course of the weaving process. Preferably, a multiplicity of such guides are combined on a single trolley carrier several of which are mounted at spaced intervals on the cam-shaped track, the movement of which is co-ordinated with the rotational movement of the warp yarn supply creel. Tension is maintained in the warp yarn supply by a multiplicity of individual roller guides mounted on spring arms which bend slightly to maintain tension in each warp yarn as the weaving shed is made and unmade.
