Title: The Innovations of Bruno Cestari
Introduction
Bruno Cestari is a notable inventor based in Collegno, Turin, Italy. He has made significant contributions to the field of electrophotography, holding a total of 2 patents. His work has advanced the technology behind photocopiers, showcasing his innovative spirit and technical expertise.
Latest Patents
Cestari's latest patents include an electrophotographic copier and a sheet detaching device for electrophotographic copying machines. The electrophotographic copier utilizes a development process that employs a magnetic brush formed on a rotating sleeve made of non-magnetic material. This design incorporates a system of permanent magnets that rotate, enhancing the efficiency of the photocopying process. The outer surface of the sleeve undergoes a sandblasting process to create a finely roughened surface, ensuring a consistent toner layer thickness. Additionally, the copier features a cold and pressure-operated toner fixing system, which utilizes rollers of different diameters to achieve perfectly flat copies. The second patent, the sheet detaching device, is designed to detach a copy sheet from the photoconductive drum of an electrophotographic copying machine. This device employs a radial protuberance on the drum, which holds the leading edge of the copy sheet through electrostatic attraction, allowing for efficient detachment during the drum's rotation.
