Abstract
A paperboard tray packaging machine is adapted to handle the tray blanks and product to be packaged as both move continually in a downstream direction. The blanks are stored in an auxiliary magazine alongside the main magazine and are transferred from one to the other individually so each tray blank can be printed, at least on the blank end walls that cannot be conveniently printed in the machine itself.
