Title: Rainer Koefferlein: Innovator in Electrographic Printing Technology

Introduction

Rainer Koefferlein is a notable inventor based in Munich, Germany. He has made significant contributions to the field of electrographic printing technology. With a total of 6 patents to his name, Koefferlein has demonstrated a commitment to innovation and excellence in his work.

Latest Patents

One of his latest patents is a transfer station with a pressure element designed for an electrographic printer. This invention allows for tandem mode operation, enabling both-sided printing of an elongate recording medium. The pressure element plays a crucial role by resiliently pressing the recording medium against the photoconductive drum during the transfer process. This feature compensates for irregularities in the recording medium. The construction of the pressure element is multilayered, consisting of a plastic foil with a metal foil arranged on top. This design effectively picks up and eliminates electrostatic charges that occur in the contact region with the recording medium, thereby preventing the caries effect in transfer printing. Additionally, the pressure element is replaceably arranged in a holder, serving as a wear part.
