Erwin Lusar has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6543354
    Abstract: A device for quickly and reliably establishing a production-run state in a printing group of a rotary printing machine after the printing cycle has been interrupted. A plurality of freely programmable memory devices having various different printing control programs stored therein may be manually or automatically connected to a control computer that determines which of the preprogrammed control programs are necessary to return the printing machine to a production-run state. The computer then controls the inking unit and, as applicable, the dampening unit in such way that its inking profile for production-run printing is quickly established.

  • Patent number: 5907999
    Abstract: The invention provides a method for arranging the inking for a pressrun in a rotary printing machine. The rotary printing machine has an inking mechanism and a dampening mechanism. The ink quantity transmitted by an ink ductor is adjusted by zone via ink zone ductor blades. When the dampening mechanism is switched off, the run-up curve of the inking mechanism is initially adjusted at an average surface coverage over the entire surface, so that a constant ink density corresponding to the average surface coverage results on the printing stock for all printing speeds. The run-up curve of the dampening mechanism is adjusted subsequently, wherein the ink zone ductor blades are in different positions which correspond to various surface coverage values of a printing subject customarily printed by the printing machine. The adjustment is effected in such a way that the ink zones with average surface coverage deliver a constant ink density to the printing stock for all printing speeds.
