A method for producing cartons, boxes or the like from a continuous sheet (1'), the carton comprising a substantially tubular, not necessarily cylindrical carton part which in cross-section has at least three sides and is formed with the aid of a continuous row of sequentially disposed carton portions which form side parts, and further comprising flap parts at at least one of both ends of the carton part at at least certain of the side parts, the tubular carton part being closed by the flap parts. The method is particularly characterized in that a sheet (1') of requisite shape is produced with the aid of a fixture (5) having a longitudinal extension which corresponds to the longitudinal extension of the tubular carton part and a cross-sectional outer profile which corresponds to the cross-sectional outer profile of the tubular carton part. An edge part (8) of a sheet of requisite size is attached to the fixture (8), preferably in connection with a longitudinally extending corner part (9) of the fixture, this corner part (9) forming a demarcation line between two mutually adjacent side parts, and where the sheet is folded, wrapped, around the fixture to form the tubular carton part and flap parts which are a continuation of the carton part. The fixture can be used as a template when it is necessary to remove excess parts of the sheet attached to the fixture. The invention also relates to apparatus for carrying out the method. <IMAGE> |
