ABSTRACT OF THE DISCLOSURE A space portion processing method and apparatus for preprocessing a slide fastener chain before attaching parts forming a separable end stop such as a retainer pin and a separable pin at the space portion of a slide fastener chain formed by cutting and removing a row of elements for a certain length from a row of coil-like continuous fastener elements of thermoplastic resin attached around a core cord along each of the facing slide edges of a pair of fastener tapes. The improvement consists in that after said space portion is detected and positioned and said slide fastener chain is held on a bed, fusion of the element cut edges at the end of said space portion into said tapes and press- forming of said core cords is carried out simultaneously by using the same pressing means. The space portion processing method and apparatus for a slide fastener chain according to the invention enables the apparatus to be made simple and compact, and allows processing efficiency to be improved, and processing costs to be lowered.
