Abstract
A folding and tucking apparatus for a container end closure forming and sealing machine where a pair of oppositely rotating arms, each having a freely rotatable roller mounted on its distal end, are adapted to engage and move a heat-activated, plastic coated carton end closure panel around a score line from a vertical to a horizontal attitude. The result is that, while the rollers thus move the panel, the relative movement between the rollers and the panel is minimal, thereby preserving clean, unmarred surfaces on end panels of cartons which will be characteristically observed by consumers in the marketplace.
