Method of producing packaging boxes and packaging boxes obtained with this method

摘要

A method of producing packaging boxes starting from pallets of sheets of board each having stamped therein a plurality of plane blanks joined in adjacent transverse and longitudinal strips by connections which can be broken and are provided with notches, fold lines and break lines defining the members for producing and closing the boxes. The method involves a sequence of steps consisting in the sequential take-up of the sheets from the pallet and the sequential separation of these sheets into strips and the separation of the strips into individual plane blanks which are supplied in individual succession to a box production line along which a respective portion defined by one of the break lines is separated and reapplied in order to obtain boxes of the flanged type after they have been folded internally around the fold lines and the production and closure members have been glued.
