Abstract: A tubular arrangement the front end of which defines a fastener outlet is extendably and contractably mounted to a fastener driver body. A drive bit is mounted within the tubular arrangement. A fastener feeder is mounted to the tubular arrangement and contains a pair of fastener guiding plates opposite each other with a predetermined distance sufficient to pass a strapped fastener assembly. One of the fastener guiding plates defines a fastener passage opening for feeding a fastener into the tubular arrangement through a fastener feed hole defined in the side wall of the tubular arrangement. A fastener feed mechanism with a feed roller intermittently engaging and advancing the strap is provided. A fastener separation element of a fastener separation mechanism passes into and out of the fastener passage clearance, presses the fastener and separates it from the strap when the fastener separation element extends out of the fastener passage clearance, to feed the separated fastener into the tubular arrangement.

Abstract: A strapped fastener assemblage for an automatic fastener driver includes a pair of connecting straps made of paper, each of which has a plastic film laminated onto one surface of the connecting strap. The plastic-film-side surfaces of the connecting straps are in contact with each other. A plurality of pin-like fasteners are arranged in parallel to one another with a predetermined spacing and each of the fasteners extend transversely of and between the connecting straps; and a plurality of fastener retainers are defined by a pair of heat-sealed portions in the connecting straps extending transversely of the connecting straps, and the fastener retainer will retain a corresponding one of the fasteners.
