<p>A chain of interengaged coupling elements on a pair of slide fastener stringer tapes is gapped and severed into short lengths of the chain with coupling element residuals or debris left on the tapes at the gapped chain portion. The chain is then manually fed between and into engagement with a pair of vertically aligned circular brushes driven for continuous rotation to scrape the coupling element residuals off the tapes. A pair of guide troughs guide the chain into alignment with the brushes, each guide trough having a pair of converging side walls confining one of the brushes solely to frictional engagement with the chain.</p> |
