ABSTRACT:
An apparatus for prealigning hex or square stock sections before chucking in a collet. As hex stock advances, pre-alignment bushing provides general alignment. A plurality of spring-loaded veliers positioned within the prealignment collar slidably contact the flats of the stock along the path of travel and urges the stock radially to the proper alignment, so that the points of the stock do not hit the collet.
