Latest Patents

Among his latest patents is a method and device for releasing a sheet from a blanket cylinder of a printing machine. This invention addresses the challenges of higher tensile forces on a sheet, which can be disadvantageous. The method involves moving elements of the impression cylinder that hold the sheet in a direction counter to the rotation of the impression cylinder, thereby producing an enlarged pull-off angle after the leading edge of the sheet has passed the printing nip. Another notable patent is for an inking unit for a printing machine, which includes zonally acting metering elements for setting ink distribution corresponding to a printing image. This invention allows for the production of two ink layer thicknesses differing from one another, enhancing the quality of printed materials.
