  • Method of and apparatus for interengaging a pair of slide fastener stringers
    Patent number: 4365403
    Abstract: A pair of slide fastener stringers are intermittently fed in a pair of longitudinal paths, respectively, in parallel planes with respective rows of coupling elements being directed in one direction. The slide fastener stringers are laterally shifted toward each other off their paths by coupler members as the latter are combined together. A presser 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. The rows of coupling elements can be interengaged when they move through the coupling channel.
