Abstract
A method of applying top end stops on to a slide fastener chain comprises holding a top end stop or stops in between an anvil and a horn, moving the anvil and the horn together into alignment with a path of travel of the fastener chain, threading the fastener chain through the top end stop, clamping and attaching the top end stop by fusion to the fastener chain, and moving the anvil and the horn out of the path of the fastener chain. This method is reduced to practice by an apparatus which essentially comprises an anvil and a horn which are vertically movable together in one instance toward and away from a horizontal path of the fastener chain and means of moving the anvil independently from and against the horn in another instance to clamp and attach the top end stop to the fastener chain.
