  • Patent number: 4745729
    Abstract: A screw head on a container-closing machine has jaws that are pivotable on a holder to grasp a closure cap and hold the cap tightly so that the cap can be screwed onto a container. For pivoting the jaws, the jaws are connected to levers, which rest on an actuating cone that is displaceable coaxially in the holder. The actuating cone is integrally connected to a piston of a cylinder-piston unit, which is likewise disposed coaxially in the holder and the piston is operable by a controlled fuel supply.

  • Patent number: 4669250
    Abstract: A device for attaching screw caps to containers has a screwing head driven by an electric motor. To avoid a high peak torque in tightening screw caps, the screwing head is coupled with the drive motor via a soft torsion coupling, which absorbs the energy of the masses that continue to rotate. The torsion coupling is embodied as a tube of a resilient elastomer. The screw cap is prevented from loosening as the masses revolve backward by means of a reverse movement stop which is associated with the screwing head.
