Abstract: A loom for weaving a slide fastener element to a tape, the loom weaving two tapes, and a slide fastener element to each tape, simultaneously. The slide-fastener element is fed along with the warp ends to the weaving area, and undergoes simultaneous shedding movement with the warp ends. The filling needle is driven in an elliptical path through each successive warp shed. The eye of the needle, through which the filling passes, moves closely adjacent to the weaving point in the first half of its path and then moves distantly away from the weaving point in the second half of its path. Each pick of the filling thereby catches and binds the slide-fastener element at a location immediately adjacent to the weaving point.
