Abstract
A necessary number of knitting needles are slid at a predetermined timing along a multiplicity of parallel sliding grooves of a single needle bed, and a predetermined number of knitting yarn guides take lapping movements to form desired stitches of the knitting yarns while a monofilament bending means between one end of the needle bed and the yarn guides is operated at a predetermined timing for reciprocating along a predetermined number of knitting yarns at an underlapping position. During this reciprocating movement, a head-portion-holding member is moved between a holding position for holding a head portion of each fastener element from an inside thereof and a non-holding position, in synchronism with the bending of a monofilament. As a result, individual fastener elements are continuously formed by bending the monofilament, which is at the same time knitted in a warp-knit fastener tape simultaneously with the knitting of the tape, so that it is possible to efficiently manufacture a woven slide fastener stringer stable in shape.
