ABSTRACT:
A loom in which each warp yarn passes through a retraction region and a shedding region, and in which means are provided for creating gaseous fluid flow along each warp yarn so that the yarns, or those that are not otherwise restrained, are moved to form a loop in the shedding region, the loops, or selected ones of them, being separated from the warp yarn sheet by gaseous fluid flow to form a shed, and means are provided for mechanically displacing portions of the yarns in the retraction region to move the yarns longitudinally into a path of predetermined length so as to draw the yarns into tension in the shedding region to close the shed. The means for drawing the yarns into tension may also be employed to draw the fell of the woven fabric against a fixed reed to beat up the inserted weft yarn.
