The method consists in applying lugs (6,7) extending from the sides of sheets (1,2) onto chamfered edges (4) of a moulding core (3), along which the different steps of the method are carried out. Optionally, the lugs present corresponding prolongations (6a,7a). The lugs, previously glued, are joined together in order to form chamfered edges (8) limited by cant edges (8a) between every two adjacent sides (9) of the box. Optionally, beside the chamfered edges (8) the lugs (6a/7a) are glued to the sides (9) of the box. This chamfered edges and the corresponding cant edges lend the box a great stiffness and resistance to withstand the compression stresses to which it may be subjected. <IMAGE> |
