Abstract: In a process and a device for the production of cardboard cutouts with glued-on second-material pieces, preferably film pieces for use as folding boxes with film window, in which the cardboard cutouts are glued at a gluing station by means of block cylinders, in order thereupon to obtain the film pieces applied by a suction cylinder, in which the transport of the cardboard cutouts occurs by suction bands, with avoidance of a contamination of the suction bands, a high precision for the applying of the film pieces onto the cardboard cutouts is ensured by the feature that the suction band or the section bands are supported in the zone of the block cylinder in such manner that partial zones defined according to construction of the supporting device of one or several suction bands are moved against the block cylinder or removed from the contact zone of the block cylinder.

Abstract: A method and an apparatus for decollating blanks of cardboard or the like stacked behind a stop in a feeding station from a magazine or stack of blanks and for feeding the blanks to a transfer station of a subsequent process operated in a machine cycle, wherein the apparatus includes at least one delivery conveyor arranged underneath the stack of blanks, and wherein the delivery conveyor includes a conveyor belt and a belt guide for the controlled removal of the respectively lowermost blank and for conveying the blank to the timed subsequent process. The transfer station of the subsequent process controls the speed of the delivery conveyor which operates without fixed cycle.

Abstract: A method and an apparatus for automatically exchanging foil rolls, particularly in the manufacture of folding boxes with foil windows, wherein the end of one foil web is automatically connected to the beginning of the next following foil web. The method includes the steps of temporarily holding the end portion of the foil web which is about to run out, simultaneously connecting the end portion to the beginning of the next foil web, releasing the end portion after the connection has been effected, subsequently severing the end of the first foil web and, during these steps, further conveying without interruptions the foil web from a loop. The apparatus includes a connecting station arranged upstream of a folding box production plant in the sequence of operation, the connecting station including a turnstile on which the foil rolls with foil webs are arranged.

Abstract: A method and apparatus for forming a fold line in a sheet of semi-rigid thermoplastic material including supporting the sheet on cylindrical rollers as the sheet is drawn forwardly along the creasing path through a creasing zone and applying a sequence of heated creasing rollers with each roller penetrating the surface of the sheet an increasing amount and immediately following the creasing by a caliper roller having shoulders for flattening the shoulders in the plastic formed beside the crease.

Abstract: Disclosed is an apparatus and method for the continuous production of packaging wrappers from cut blanks of flat material. A flap-like portion of the blank material is abraded in a particular fashion to produce an area which upon folding and gluing provides a bonded joint having a thickness in the area of the bonding essentially equal to the thickness of the flat material of the wrapper. The packaging wrapper produced possesses an interior surface completely void of protrusions or uneven areas and an overall wrapper of even thickness throughout.
