  • Publication number: 20170080663
    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.

  • Patent number: 9539784
    Abstract: 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.

  • Patent number: 8382648
    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.
