Abstract
A fastener group device includes a feeding gear for meshing with connecting elements of a fastener group, a feeding pawl for intermittent rotation of the feeding gear, a stopper for preventing reverse rotation of the feeding gear and a feeding cam for raising and lowering the feeding pawl. The feeding pawl includes a ratchet and spring, the spring for biasing the ratchet toward the feeding gear. An escape space into which the spring enters following rotation of the feeding gear is provided rearwardly of the feeding pawl. When the spring is received by the escape space, the spring is substantially inoperable for biasing the ratchet toward the feeding gear.
