ABSTRACT:
This apparatus includes a carriage by which a garment workpiece is moved relative to a stationary fastener applicator unit. The workpiece is held extended between pneumatically actuated clamping units mounted to the carriage which apply a tensioning force to the workpiece while fasteners are being applied sequentially thereto during dwell periods between intermittent advancements of the carriage. A latching and indexing assembly is provided which includes a locating pin that precisely secures the carriage in each of a series of predetermined locations during the dwell periods, to assure accurate placement of the fasteners on the workpiece. A sensing device detects any malfunctioning of the applicator machine and should such malfunction occur, stops the apparatus.
