  • Publication number: 20190152217
    Abstract: The invention is about a convenient way of fixing a sleeve over a mandrel in a press. The sleeve is attached by applying a hydraulic pressure into the mandrel which deforms itself and grips on the sleeve. The pressure is brought by a piston mounted on a screw inside the mandrel, which when tightened increases the pressure and grips the sleeve.

  • Publication number: 20190147576
    Abstract: A method of inspecting the quality of blanks (2n) to be processed into packaging material, includes the following steps: A carrier (1) with a plurality of blanks (2n) is supplied. Each blank (2n) is identified in accordance with its position (n) on the carrier (1), and a scanned image (Sn) of each blank (2) is obtained, and each scanned image (Sn) is compared with a reference image (Rn) associated with the specific position (n) of the blank (2n) from which the image was taken. Based on the result of the comparison, the respective blank (2n) is accepted or rejected. Furthermore, there is a quality inspection system (10) comprising a digital imaging unit (12) for scanning images of blanks (2n) on a sheet (1), a unit (16) for generating individual reference images for each blank, a storage (18) for storing the individual reference images (Rn), and a comparator (20) for comparing scanned images (Sn) of a blank with the individual reference image (Rn) for this blank (2n).
