ABSTRACT:
A fin pass roll for use as a single roll or as pairs of mating forming rolls for bending a flat metal strip into a desired tubular shape or a tube form. The fin pass roll is split into three sections; that is, a fin roll having a fin and fin side rolls in such a way that the fin roll may have arcuate caliber profile which are extended to both sides from the fin and merge with the arcuate caliber profile of the adjacent fin side rolls. The fin side rolls are rotatable in unison with a drive shaft, but the fin roll is so constructed and arranged as to be rotatable independently of the drive shaft and hence the fin side rolls.
