A carton blank may be folded by folder blades supported on an adjustable plate positioned on one side of a chain which carries a clamp by which the carton blank is pulled through the machine. After folding, the blank is glued to complete a flat shell and the shell is then inverted; the clamp is articulated so the shell may be turned in a horizontal plane to align a datum line on the shell to a datum line on a cartoner machine.

In a machine for folding carton blanks along score lines, gluing down a glue flap on the carton, and delivering the glued carton to the supply magazine of a cartoner machine where the carton is erected and then filled by moving the erected carton along a filling path: means to clamp and pull each carton blank progressively through folding and gluing stations along a folding axis parallel to but spaced from the filling path of the cartoner machine with said one score line also being parallel to said filling path as the blank is being moved through said folding and gluing stations; means at said stations respectively to fold the blank and glue said glue flap to an opposed surface of the blank; means to invert the blank after it is glued and while it is still clamped; and means to deliver the inverted blank to the supply magazine of the cartoner machine.
