An apparatus for coupling a pair of elongate slide fastener stringers while being fed longitudinally along a pair of respective paths, comprises a pair of first spaced rolls rotatable on a first shaft on a frame, a pair of second spaced rolls rotatable respectively on a pair of second shafts on the frame, which extend transversely to the first shaft, a pair of third rolls rotatable respectively on a pair of third shafts on the frame, which extend substantially parallel to the second shafts and are spaced from each other by a greater distance than that between the pair of second shafts, and a pair of fourth spaced rolls rotatable respectively on a pair of fourth shafts on the frame, which extend transversely to the third shafts. A coupling member on the frame has a pair of converging guide channels for meshing the stringers as they are withdrawn therethrough by withdrawing means. The first, second, third, fourth rolls, the coupling member and the withdrawing means are arranged in the order names for guiding the stringers along their respective paths into the coupling member. The third rolls enable the stringers to pass along a pair of converging paths leading respectively to the converging guide channels in the coupling member. The fourth rolls cause the stringers by width-wise engagement therewith to advance in a plane in which the converging guide channels lie.
