ABSTRACT:
The hook sheet of a separable hook-and-loop area fastener is formed by weaving, looping or otherwise engaging with a backing sheet a continuous plastic filament, preferably of nylon or the like, which has been permanently crimped into a zig-zagged sawtooth configuration by passing the same between a pair of rotating oppositely sawtoothed forming rolls. The continuous plastic filament loops are preferably formed in a plurality of aligned rows so that a plurality of loops may be engaged by a common elongated knife edge and simultaneously cut. The loops preferably are large enough and the sawtooth formations small enough so that a plurality of sawteeth are provided in each loop. When cut, the zig-zag sawtooth monofilaments stand up perpendicular to the sheet support, and are provided with a plurality of hook-like formations. A loop pile sheet for engagement with the hook sheet may be conventional.
