ABSTRACT:
In a slide fastener stringer having a row of discrete fastener elements arranged along one longitudinal edge thereof and each comprising a coupling head at its front end and a pair of parallel spaced legs extending rearwardly from the coupling head, the rear end portions of the legs of each fastener element are flattened into plate-like shape, with steps formed between these flattened rear end portions of the respective legs and their remaining portions. The flattened rear end portions of the legs of each fastener element are embedded into the stringer tape from both surfaces thereof, to such a degree that the outer surfaces of the flattened rear end portions are flush with the corresponding surfaces of the stringer tape, thereby providing slideways for the marginal guide flanges of a slider traveling along the fastener elements.
