Abstract of the Disclosure: Disclosed is an injection molding apparatus for the manufacture of continuous slide fastener chain. In the dis- closed arrangement a small projection is formed on a portion of a runner molded together with a row of fastener elements at the time the elements are injection molded on a pair of stringer tapes, the small projection being detected as a portion of the as yet unfinished slide fastener chain when the stringer tapes are fed. Upon detection of the projection the introduction of the tapes into the molds is halted and. the tapes, which have been intentionally fed to an excessive degree, are retracted by an amount equal to such excess. During the retraction the posterior end of the runner abuts a stopper provided on one of the pair of molds thereby to position the tapes for the next injection molding cycle.
