Title: Michael Dotzert: Innovator in Printing Technology

Introduction

Michael Dotzert is a notable inventor based in Friedrichsdorf, Germany. He has made significant contributions to the field of printing technology, holding a total of 4 patents. His innovative designs focus on enhancing the efficiency and functionality of printing machinery.

Latest Patents

One of Dotzert's latest patents is a lifting drive system for an automatic pile changing device. This invention pertains to a lifting device for a sheet-processing machine, particularly for a sheet-fed offset printing machine with a non-stop feeder. The system features a main pile-carrying assembly and an auxiliary pile-carrying assembly that can be raised and lowered by a motor and an upstream drive unit. This invention allows for simple and cost-effective synchronization of both assemblies within specified tolerances. The synchronization is achieved through switching signals of equal duration, coordinated by a common control unit that manages two drive units.

Another significant patent is for a swivelable cylinder driven by an electric individual drive. This invention involves a cylinder for a printing press that is adjusted away from a printing stock web or an adjacent cylinder by rotating an eccentric element. The position change caused by the eccentric element's movement is compensated by an additional rotating movement, ensuring that the outer surface of the cylinder maintains no relative velocity with respect to the adjacent cylinder or the printing stock web. This compensation is managed by a regulating circuit that receives the actual rotational angles of both the cylinder and the eccentric element.
