Abstract (en)
[origin: WO2004108400A2] The invention relates to a method and device for producing packing coverings for composite cardboard/plastic packages, in particular beverage packages provided with an opening. Said invention provides a reliable solution for a mentioned problem in such a way that no contact is possible between raw cardboard material and a product in the area of a pouring aperture even after a first package opening. Said result is achieved by the following operations: punching out an opening (O) in the extended raw cardboard material (1) in the area of future pouring apertures, covering said raw cardboard material with a plastic layer and composite material grooves (1') on two sides thereof, punching out the pouring apertures (P) in the area of the openings (O) coated with a composite material web (1'), the pouring apertures being smaller than the punched openings (O), individually separating the composite material (1') with cut parts and sealing a longitudinal seam (L) in order to form a packing covering (M).
