ABSTRACT:
A slide-fastener stringer half has a coupling coil having a row of turns defining a longitudinal passage and each formed with a coupling head, an upper leg and a lower leg extending transversely from the head and flanking the passage, and a bight extending from one of the respective legs to the other leg of the adjacent turn. A knitted tape against which the lower legs engage and from a longitudinal edge of which the heads project is formed of a plurality of outer warp chains adjacent the coil, an upper warp chain overlying both the upper and lower legs of the coils, and a lower warp chain overlying only the lower legs of the coil and extending along the passage between the upper and lower legs of the coil. Thus with this system the group of filaments forming the lower warp chain takes the place of the normally provided filling cord.
