Abstract

A machine and method for continuously orienting and tapping fasteners such as pierce nuts with the nuts being advanced in face-to-face manner aligned on the machine feed path. The machine is operable in one mode, in combination with nut collection means, to receive strips of the nuts from the feed path in side-to-side array for delivery in installation-ready coiled strips to an installation assembly or the like. One embodiment of the collection means includes apparatus for collecting and dispensing the nuts in unconnected linear stacks. Tapping of the nuts is performed by the machine in a 'reverse flow' or deferred manner just prior to the nuts being dispensed from the feed path with the tapped nuts maintained in face-to-face spaced array. The machine reverse flow tapping provides for burr clearance between the spaced nuts to thereby assure that tapping burrs will not improperly position the nuts obviating machine jamming and thread obstruction by such burrs. A continuous nut orienting apparatus is operative, upon receiving nuts aligned in face-to-face abuttment but in random angular orientation, to provide successive nut rotational movement about the feed path in predetermined directions orienting the nuts in face-to-face abutting array.
