METHOD OF AND APPARATUS FOR AUTOMATICALLY FINISHING SLIDE FASTENERS

摘要

A slide fastener chain is fed along a chain path by a feedout mechanism until a leading end of the chain gripped by the feedout mechanism reaches a first feeder mechanism past a cutting mechanism. The first feeder mechanism is then actuated to feed the chain toward a second feeder mechanism. The first feeder mechanism is then inactivated and the second feeder mechanism is actuated to feed the chain at a higher speed. A slider on the chain is engaged by a slider sensor to intermesh element rows on the chain as it is transported by the second feeder mechanism. Then, a chain stop of a stop mechanism is inserted into an element-free gap in the chain and engaged by a bottom stop following the element-free gap to stop the travel of the chain. The second feeder mechanism is released and the cutting mechanism is actuated to cut off the chain across the element-free gap to produce a slide fastener, which is discharged by the second feeder mechanism into a sorting mechanism. Any defective slide fastener length having no slider is rejected by the sorting mechanism, and complete slide fasteners are delivered into a storage mechanism from which they can be picked up.
