Abstract
In a method and apparatus for forming a space section in a pair of concealed-slide-fastener stringers, with a pair of tapes gripped with interengaged coupling elements disposed at the upper side of the tapes, a pair of continuous concealed-slide-fastener stringers is pushed upwardly from the under side of the tapes by a pair of laterally spaced and vertically movable dies until head portions of a series of the interengaged coupling elements are exposed to the dies and supported thereon. A punch is then lowered to cut upper legs of certain interengaged coupling elements supported on the raised dies. Finally, an ejector is raised through the dies to clamp the cut coupling elements against the punch and continues to be moved upwardly together with the punch to pull the cut coupling elements out of sewn stitches.
