Abstract
A pneumatically operated and controlled fastener feeder and driver apparatus supplies individual fasteners, such as screws having a head and a threaded shank portion, which are maintained on a carrier strip in a magazine assembly, to a nose assembly of the fastener feeder and driver apparatus. When a fastener is positioned in the nose assembly, a driver member of a power fastener driving tool engages the fastener and positions the fastener such that the fastener extends out from a workpiece engaging surface of the nose assembly. When the fastener is driven into the workpiece to a specified depth, a pneumatically operated and controlled driver mechanism moves the fastener driving tool away from the workpiece. Thereafter, the fastener strip is incrementally advanced by a pneumatically operated feeding mechanism so that a next one of the individual fasteners on the strip is positioned within the nose assembly and the driver mechanism moves the fastener driving tool toward the fastener so that the fastener is removed from the fastener strip, positioned so as to be extending out from the workpiece engaging surface and ready for driving into the workpiece.
