The method of interengaging a pair of slide-fastener stringers(2,3)involves intermittently feeding the stringers along a pair of longitudinal paths in parallel planes, with respective rows(5) of coupling elements on the stringers that are directed in one direction. The slide-fastener stringers are laterally shifted toward each other off their paths by coupler members (40,42) as the latter are combined together. A presser(48) is moved into coaction with the combined coupler members to define a generally Y-shaped coupling channel, in which the rows of coupling elements are forced into confronting relation.
