Abstract
A carton leading and trailing end panel folding mechanism for use with a tubular carton blank mounted on a mandrel, with the end closure panels extended beyond the face of the mandrel. The main folding mechanism is a single freely rotatable roller which serves to first fold the leading panel rearwardly as the latter rotates therepast, and then to engage and fold the trailing panel forwardly as it rotates therepast. The roller may be stationary until contacted by the leading panel.
