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. First and second actuators both mounted to the fastener driver body actuate the respective fastener feed and fastener separation mechanisms.
