  • Patent number: 12319458
    Abstract: A sealing device includes a sealing holder for fixing a sealing jaw of the sealing device, and a further sealing holder for fixing a further sealing jaw. The sealing holder and the further sealing holder are arranged on a mechanical coupling unit and are supported movably relative to each other. The coupling unit includes a force transmission element and a further force transmission element, the force transmission element being configured to transmit a sealing force to the sealing holder in the form of a pressure force. The further force transmission element is configured to transmit the provided sealing force to the further sealing holder in the form of a traction force. The coupling unit comprises a piston unit with a piston chamber and a piston. The piston is connected with one of the force transmission elements and the piston chamber is connected with another one of the force transmission elements.

  • Publication number: 20240425217
    Abstract: The invention is based on a sealing device for a longitudinal sealing apparatus of a packaging machine, with at least one sealing holder (14) for a fixing of a sealing jaw (16) of the longitudinal sealing apparatus, with at least one further sealing holder (18) for a fixing of a further sealing jaw (20) of the longitudinal sealing apparatus, the sealing holder (14) and the further sealing holder (18) being supported movably relative to each other, and with a mechanical coupling unit (22) which the sealing holder (14) and the further sealing holder (18) are arranged on, wherein the coupling unit (22) comprises at least one force transmission element (24) and a further force transmission element (26, 28), the force transmission element (24) being configured, during a sealing, to transmit a provided sealing force to the sealing holder (14) in the form of a pressure force, and the further force transmission element (26, 28) being configured, during a sealing, to transmit the provided sealing force to the further
