The object of the invention is a method for manufacturing boxes made of paper or cardboard, whereby the boxes have a base or a lid with a glued-on sidewall and the sidewalls are formed from a strip (1) with a beginning (4), an end, and connecting tabs (3) on a long side. First, the connecting tabs (3) are bent by about 900. Next, the strip beginning (4) is placed against the lateral surface (11) of a cylindrical matrix (10), whose cross section corresponds to the cross section of the box, with the aid of a patrix (20) and attached by means of vacuum. Next, the matrix (10) is rotated. In so doing, the strip (1) is suctioned by vacuum onto the lateral surface (11) and held in place. After application of an adhesive at the beginning (4) or end of the strip (1), the beginning (4) and end of the strip are glued together. A base along whose periphery an adhesive bead was applied is then pressed onto the connecting tabs (3). After the adhesive has hardened, the finished box can be removed from the matrix (10). |
