ABSTRACT:
The present invention is concerned with a machine for producing non-woven "glued" carpets and particularly with operating mechanism for alternately pressing a "pile-yarn" sheet against one and then the other of a pair of opposed adhesive-carrying backing layers or sheets between which the pile-forming fibrous materials or yarns are fed as in the form of a longitudinally advancing warp sheet moving concurrently with the backing sheets. After setting of the adhesive layers, which generally is effected during their concurrent advance, the intervening pile-forming sheet is cut to form two non-woven cut pile-surfaced carpets, in each of which the pile "yarns" project from the backing fabric or layer to which the pile is adhered. The present invention is particularly concerned with the mechanism for driving the presser bars, blades or plates alternately against opposite sides of the pile-forming sheet and thereby pressing the latter sheet against the adhesive-coated surface of the backing layer or sheet. The invention is also more particularly concerned with the control means and a manner of operating such means to provide an operating system that is characterized by high versatility in respect to the variety of carpets that may be produced, e.g., cut-pile, looped-pile, pile heights, etc. Hereinafter, the "pile-forming" fibrous sheet may be termed simply "fibrous sheet" or "warp sheet."
