摘要：

1. In a beaded can bodymaker wherein flat blanks are passed individually from a stack of blanks first transversely and then longitudinally of the machine, the combination comprising a pair of parallel horizontal flexing rolls in the transverse path of travel of said blanks, the first of said flexing rolls having a larger diameter than the second, the second of said flexing rolls having its axis of rotation spaced forwardly with respect to said first roll in the transverse path of travel of said blanks, means for rotating said flexing rolls in opposite directions, a first horizontal guideway in advance of said second flexing roll and below the level of the line of contact of said rolls, a second horizontal guideway below the level of said line of contact and rearward of the axis of rotation of said first roll, a first breaker steel above the level of said line of contact and in advance thereof and partially over said guideway and said second roll, a second breaker steel rearward of said line of contact and in close proximity to said first roll and above said second guideway, said flexing rolls, guideways, and breaker steels being spaced and positioned with respect to each other so that the path of travel of said blanks therethrough is reversely bent to flex said blank in two directions beyond the elastic limit of said blanks, a pair of beading rolls locatedl proximate said flexing rolls in the transverse path of travel of said blanks, said beading rolls having their axes of rotation parallel to said flexing rolls and substantially in vertical alignment, one of said rolls having at least one circumferential bead and the other of said rolls having a circumferential groove corresponding to each said bead, and means for rotating said beading rolls in opposite directions.
