Latest Patents

**Eccentric Device for Adjusting Printing Unit Cylinders**

This invention describes a device for engaging and disengaging printing-unit cylinders in a rotary press that prints on a web of material. It combines a first adjusting unit for printing-form cylinders with a second, eccentric adjusting unit for transfer cylinders. The arrangement allows cylinders within the lower and upper printing units to engage as required while keeping the transfer cylinders of those units disengaged from one another.

**Device for Adjusting Printing Unit Cylinders in Printing Units of Rotary Presses**

This invention concerns a rotary press that prints on both sides of a material web. Its auxiliary adjusting unit maintains a gap between adjacent cylinder surfaces along the web’s path, independently of the adjusted positions of the other printing-unit cylinders. The design helps preserve a traversable path for the material web.

Career Highlights

Roland’s listed inventions address practical adjustment requirements in rotary printing equipment. They focus on controlling cylinder positions, managing engagement between printing components, and maintaining clearance for material moving through the press. He is associated with Heidelberger Druckmaschinen AG, a company known for printing machinery.
