ABSTRACT:
An apparatus is provided for continuously and automatically forming a fastening material in the form of a sheet or strip containing a multitude of filament-like fastening formations protruding from at least one surface thereof and capable of hooking engagement with similar or differently configured formations provided in a second sheet or strip. In one form, the filamentary formations are continuously or intermittently molded in a plurality of preformed strips of plastic which may be extrusion formed as they are fed or fed from a plurality of coils thereof and the filament containing strips are twisted 90.degree. after the filamentary formations are molded therein to bring the edges of each strip into abutment with the edges or edge portions of adjacent strips whereafter they are continuously welded or otherwise fastened together to form a sheet-like array of strips containing a plurality of parallel rows of filamentary formations. In another form plastic material is continuously or intermittently injection molded into a plurality of strips which are brought into edgewise abutment with each other and welded together to form a wider strip or sheet containing a plurality of rows of filamentary fastening formations. The invention is also drawn to improve configurations in strip-like filamentary material including certain containing hooks, barbs and loop formations.
