Kind Code:
B2
Abstract:
A method is disclosed for making a slideless or slide-free fastener. The steps include forming first and second rows of cuts in a tape or band made of resilient material, the cuts being preferably arcuate or semi-circular in shape, though not limited thereto, the cuts in each row being spaced a predetermined distance apart, the cuts in one row being paired in reverse with respect to those in the other, rows of tongues being formed by bending up the cut-out portion of the band or tape then heat-setting the same, forming a third row of cuts between said first and second rows, the cuts in said third row being a straight line but at such an angle as to join the closest ends of each pair of cuts in said first and second rows to form a series of openings. The openings in the tape or band-like fastening element so produced can be closed by a spiral fastening element made by sewing a resilient monofilament formed into a spiral onto a band or tape. The slideless or slide-free fastener produced by the foregoing method is joinable with sheet material and is also disclosed.
