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.

Abstract: The present invention is concerned with a novel and improved cutting mechanism for slicing a flexible sheet that is being advanced endwise continuously to the cutting position. It is particularly advantageous in the slicing of textile materials that are formed continuously as in a carpet making machine, such as those produced by a non-woven bonding procedure described in U.S. Pat. No. 3,657,052.The present invention comprises an endless belt stretched about two sprockets. The cutting elements are secured to the belt at intervals therealong. Supporting guide means are positioned beneath the upper course or stretch of the belt to assure that the cutting edges of the cutting elements carried thereby follow a path lying in the plane of cutting extending transversely of the width of the sheet being sliced. Means is provided to drive the belt alternately in both directions so that these knives can be reciprocated in the plane of cutting.
