Abstract
Apparatus is provided for forming a chime bead adjacent the closed end of a seamless cup-shaped metal can body and a plurality of peripheral beads intermediate the opposite ends of the can body. The apparatus includes a plurality of beading spindles receiving and supporting can bodies for movement along an arcuate path. The beading spindles are provided with beading tool portions corresponding to the chime and intermediate beads to be formed on a can body. The frame supports axially offset and sequentially arranged outer beading rails positioned along the arcuate path of spindle movement. During movement of the spindles along the path between input and output stations of the apparatus, can bodies on the spindles are rotated about the spindle axes and, as each can body moves past the outer beading rails, the beading tool portions of the spindles and the outer beading rails cooperatively engage a can body therebetween to sequentially form first the chime bead and then the intermediate beads on the can body. The outer beading rails are supported on the frame of the apparatus for adjustment of the positions of the beading rails axially, laterally and radially with respect to the axis o…
