  • PROCESSING APPARATUS FOR OPTICAL WORKPIECES AS WELL AS USE OF A DOUBLE GRIPPER
    Publication number: 20230150078
    Abstract: A processing apparatus for optical workpieces and the use of a double gripper are proposed, wherein a swivelable changing device with a double gripper is arranged between a milling station and a turning station. Thus, parallel processing can be performed in the milling station and the turning station and the workpiece changing time can be minimized.

  • GAS BEARING AND METHOD FOR PRODUCING SAME
    Publication number: 20220065288
    Abstract: The invention relates to a gas bearing for contactlessly bearing a rotatable element (50). The gas bearing comprises: a housing (100) having an opening for receiving the rotatable element; and at least two sliding films (200), which are arranged on an interior (110) of the opening without overlap and which each have a first end portion (210) and a second end portion (220) for support on the housing (100). The sliding films (200) are designed to radially support the rotatable element relative to the housing (100) only by means of the first and second end portions (210, 220), the second end portion (220) providing frictional contact with the interior (110) and the first end portion (210) being fastened to the housing.

  • Method and device for producing and transferring diffractive microstructures to a printing material and printing press having the device
    Patent number: 9573359
    Abstract: A method and a device for producing and transferring diffractive microstructures to a printing material include applying a fluid to an embossing cylinder and there, during the rotation of the embossing cylinder, solidifying the fluid to such an extent that the fluid is transferred to a printing material in the manner of a film with a solidified microstructure. The embossing cylinder has a cover which is preferably constructed to be either soft as a “flexoshim” or hard as a “nickel shim.” A web-fed or sheet-fed rotary printing press having the device is also provided.
