Abstract
Abstract A method and apparatus for weaving a row of slidefastener links into the edge of a tape which is formed on a needle loom which feeds the links in the direction of the warp while simultaneously weaving the tape from warp and weft threads. At least one pair of warp threads tie an edge of the links into the edge of the tape, while the weft threads form loops which engage the links from the outside and run in an opposite direction over and under the row of links. Guiding means aid in tying off the warp threads and weft thread loops which pull in opposition to each other near the reed stop of the loom.
