Apparatus comprising a frame (11), a series of four pairs of guide rolls (25,26,31,32,43,44,58,59) rotatable on shafts on the frame, a coupling member (12) provided with a pair of V-shaped converging guide channels (17,18) and withdrawing means (74,77). Said first (25,26), second (31,32), third (43,44), fourth (58,59) pairs of rolls, coupling member (12) and withdrawing means (74,77) are arranged in the order named for directing a pair of continuous sliding clasp fastener stringers (20,21) along their respective paths leading in coplanar relation to the pair of guide channels (17,18) in the coupling member (12) and so that the row of coupling elements (22) of the stringers can be interengaged smoothly and reliably without damage to the stringers. |
