  • Patent number: 9283638
    Abstract: A device forms grooves or slits in a material web as it moves in a longitudinal direction. The grooves or slits, which are spaced apart from one another in the longitudinal direction, are formed by a laser beam. A laser beam source generates a continuous laser beam and a deflection mirror directs the laser beam onto the material web. The mirror rotates about an axis of rotation and it is displaceable along the axis. The mirror has a first mirror face, the line of intersection of which with a sectional plane perpendicular with respect to the axis of rotation forms a circular arc which varies depending on the axial position of the sectional plane. A second mirror face deflects the laser beam towards an absorber. Focusing optics focus the laser beam, after reflection from the first mirror face, onto the moving material web.

  • Patent number: 6147320
    Abstract: The apparatus has a processing chamber in which a workpiece is processed with a processing tool. Additionally an introducing device is provided as part of the processing chamber wall, being disposed such that a closed space is formed at least during processing of the workpiece in the processing chamber. Additionally one disposes on the introducing device at least one workpiece holder that is rotatable by a drive about a rotation axis in the workpiece plane and is moved in or out of the processing chamber by the introducing device.
