Title: The Innovative Contributions of Keith K Klett
Introduction
Keith K Klett is a notable inventor based in Danville, IL (US), recognized for his significant contributions to the field of gravure printing technology. With a total of 6 patents to his name, Klett has developed innovative solutions that enhance the efficiency and effectiveness of printing processes.
Latest Patents
Among his latest patents is the "Gravure press with crowbar circuit." This invention features a gravure printing press equipped with an electrostatic assist unit that includes a fault detection circuit and a crowbar circuit. The crowbar circuit utilizes a transformer with a primary winding and multiple secondary windings. Each secondary winding is connected to a field-effect transistor that activates upon detecting a fault condition, effectively reducing the voltage applied to the press to zero and removing any electrostatic charge. Additionally, a capacitor is integrated to prolong the on-time of the transistors.
Another significant patent is the "Rotogravure cylinder proofing method." This method outlines a procedure for conducting a proofing operation on a rotogravure printing cylinder. It involves preparing a steel drum layered with plastic, a rubber composite blanket, a paper/foil layer, and a proofing sheet made of normal printing paper. The rotogravure cylinder is then brought into contact with this drum, and a high voltage is applied to the foil, facilitating ink transfer from the cylinder to the proofing sheet. This process allows for a complete impression to be checked before the cylinder is sent to the user.
