Abstract

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 with a beginning, an end, and connecting tabs on a long side. First, the connecting tabs are bent by about 90°. Next, the strip beginning is placed against the lateral surface of a cylindrical matrix, whose cross section corresponds to the cross section of the box, with the aid of a patrix and attached by vacuum. Next, the matrix is rotated. In so doing, the strip is suctioned by vacuum onto the lateral surface and held in place. After application of an adhesive at the beginning or end of the strip, the beginning and end of the strip are glued together. A base along whose periphery an adhesive bead is applied is then pressed onto the connecting tabs. After the adhesive has hardened, the finished box can be removed from the matrix.
