Abstract
A drive chain cooperative with a guide for successively advancing can bodies (or the like) coaxially is pivotally fitted with longitudinally spaced driving lugs adapted to grip the respective trailing ends of the bodies and thus prevent their unwanted shifting about their longitudinal axes. Each lug, in addition to its projection for gripping the trailing end, has a flat portion, slidably engageable with the guide to insure non-deviation of side seam body joints from alignment with a solder applicator. A sprocket beyond the guide and the applicator, and with which the chain is in mesh, has circumferentially spaced protrusions which pivotally actuate the lugs to release the can bodies for further processing.
