ABSTRACT:
The present metal spin forming head includes two sets of rollers, with each set having a series of individual metal working rollers therein. The rollers of each set are circumferentially spaced evenly about the head, with each of the rollers of the second set being evenly positioned between corresponding rollers of the first set. The second roller set may be in a non-coplanar relationship with the first roller set. The first roller set comprises rollers having relatively broad widths, for forming the general contours of the workpiece. The second roller set comprises rollers having relatively narrow rims for forming circumferential grooves in the workpiece, resulting in corresponding beads within the workpiece for securing an article therein. The rollers are controlled independently of one another by a programmable logic control capable of driving the rollers cyclically as the workpiece (or spin forming head) rotates to form non-cylindrical shapes.
