Abstract
A chain feeder for used in a slide fastener finishing machine includes feed roller mounted on a driven shaft driven to rotate in one direction via a clutch and a spring-biased brake lever mounted on the driven shaft via a one-way clutch for exerting a braking force to the driven shaft when the feed roller is rotated in the opposite direction. With this chain feeder thus constructed, the fastener chain is held taut during the time top stops are applied to the fastener chain.
