ABSTRACT OF THE DISCLOSURE An apparatus for producing a woven slide fastener stringer includes a loom for weaving a stringer tape and a rotor assembly for coiling an element-forming monofilament around a mandrel to form a coiled coupling element, which is then woven into the stringer tape along a longitudinal edge thereof. The rotor assembly comprises a rotor rotatably mounted eccentrically on a stationary shaft, and having a guide hole for passage therethrough of the monofilament and a pin angularly spaced 180 degrees from the guide slot and slidably received in a radial slot in a radial arm to which there is drivingly connected a drive shaft rotatably mounted on the stationary shaft. When the drive gear rotates, the guide hole rotates at a reduced angular velocity as it approaches the loom, thereby allowing harnesses for warp threads which bind the coupling element to be moved across the orbital path for the monofilament without interference.
