Abstract
A method and device for producing boxes is provided. The boxes include a cut-out shape in the form of the bottom or the lid, with a lateral wall. The lateral wall is formed from a strip having a beginning, an end, and connection tongues. Then, the beginning of the strip is applied and fixed to the lateral surface of a cylindrical female mould having a cross-section corresponding to the cross-section of the box, by means of a male mould. Then, the female mould 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 is pressed onto the connection tongues.
