ABSTRACT:
In a machine for packaging articles in a tray carton a first stationary rail section folds up the end panels of a moving tray carton blank to an intermediate position and, after the application of glue to either the end flaps or the end panels, a third stationary rail section completes the operation of folding the end panels of the moving blank up against the end flaps. A second normally stationary section located between the first and third sections maintains the end panels in their intermediate positions. When the machine stops for any reason the second section moves the end panels of the tray carton located at that station into contact with the end flaps to adhere the end panels to the end flaps of the stationary tray carton.
