A slide fastener chain comprises a pair of inter-engaged stringers including a pair of stringer tapes one longer than the other which have longitudinally staggered ends spaced from each other by a distance greater than the length of a slider which is to be mounted on the slide fastener chain. The coupling heads of a predetermined number of coupling elements on the longer stringer tape adjacent to the end of the shorter stringer tape and remote from the end of the longer stringer tape are cut off so that the coupling elements thus severed are kept uncoupled from opposite companion coupling elements on the shorter stringer tape. The slide fastener chain thus constructed can smoothly be threaded through the slider. The slide fastener chain in one form is fabricated by cutting a continuous slide fastener chain transversely fully thereacross to define a transverse edge of the chain, transversely fully across one of the stringers to form a transverse slit spaced from the transverse edge, and longitudinally across a certain number of coupling elements below the transverse slit to form a longitudinal slit cutting off the coupling heads, which are held between the opposite companion coupling elements. |
