In a method for raising creased and flattened parallelepipedic blanks to form rectangular containers, a front edge of a blank is discharged from between a pair of rollers and is moved back towards the rollers by pressure from a pusher. This opens the blank to such a degree that it now extends nearly perpendicular to the discharge direction. Subsequently the pusher is withdrawn to allow the blank to return to a rectangular cross section. |
