ABSTRACT:
A fastener feeding apparatus provides an aperture for inserting fasteners into the interior of the apparatus so that the fastener lies on the longitudinal axis of the apparatus. A bit is then forced into contact with the fastener in order to engage it for mutual rotation and translation. A set of flexible leaves are preformed to press inwardly against the shank of the fastener so as to maintain its axial orientation. The bit is driven to force the fastener to move through the apparatus while rotating. The leaves move radially outwardly to accommodate the head of the fastener.
