A method and device for producing boxes from paper or cardboard is provided. The boxes include a cut-out shape in the form of the bottom or the lid, with a lateral wall stuck thereto. The lateral wall is formed from a strip having a beginning, an end, and connection tongues are bent by up to 90° C. Then, the beginning of the strip is applied and fixed to the lateral surface of a cylindrical female mold having a cross-section corresponding to the cross-section of the box, by means of a male mold. Then, the female mold is turned. The strip is sucked onto the lateral surface and held in place by means of a vacuum. After an adhesive has been applied to the beginning or end of the strip, the beginning and end of the strip are stuck together. Then, a cut-out shape in the form of the bottom or the lid, which has previously had adhesive applied to the periphery thereof, is pressed onto the connection tongues. Once the adhesive has hardened and the vacuum has been stopped, the finished box can be removed from the female mold.
