The method of manufacturing an assemblage of fasteners which comprises the steps of
- (a) molding the assemblage as a set of connected individual fasteners, each individual attachment including an end member which is joined by a filament, and
- (b) stretching the individual fasteners simultaneously while subjecting them to controlled heating at a prescribed position along the lengths of their filaments and protecting the end members from adverse heating effects, with said controlled heating being directed to the filaments simultaneously.
The method of manufacturing an assemblage of fasteners which comprises the steps of
- (a) molding the assemblage as a set of connected individual fasteners, each including an end member which is joined by a filament, and
- (b) stretching the individual fasteners simultaneously while subjecting them to controlled heating at the junctions of their filaments with their end members and protecting said end members from adverse heating effects, with said controlled heating being directed to the filaments simultaneously.
