Title: Werner Demny: Innovator in Rolling Technology
Introduction
Werner Demny, an accomplished inventor based in Dusseldorf, Germany, has made significant contributions to the field of rolling technology, particularly in the production of tubes and metal forming. With 11 patents to his name, Demny's innovative solutions have improved efficiency and reduced waste in metalworking processes.
Latest Patents
Among Demny's recent patents is a cutting-edge design for a rolling mill used in the stretch-reducing of tubes. This invention introduces a method that enhances the elongation and tension within the rolling process. By increasing the speed of an auxiliary drive motor relative to that of the main drive motor, it effectively reduces the length of the trailing 'thickened end' of the tube that would normally be discarded as scrap. This method is predicated on accurately predicting the start of the trailing end portion, allowing for a controlled rolling process that minimizes material waste.
Another notable patent from Demny is a design for rolling lines that is adaptable for billets, bars, wire rods, and similar materials. This invention incorporates multiple rolling stands equipped with driven rolls adjustable by a worm drive and a screw mechanism. The innovative approach enables the rolls to progressively close before each pass of the work material, thus reducing the cross-section and elongating the material efficiently. Additionally, the design allows for the direction of the rolls to be reversed, enhancing versatility in the rolling process.
Career Highlights
Demny has had a notable career in the field of metalworking technology, working with distinguished companies like Friedrich Kocks GmbH & Co. and Kocks Technik GmbH & Co. His tenure at these firms has not only facilitated the development of his patents but has also positioned him as a prominent figure in contemporary rolling technologies.
Collaborations
Throughout his career, Demny has collaborated with talented individuals such as Hans Brauer and Hermann Moltner. These partnerships have fostered an environment of innovation, allowing for the exchange of ideas and the enhancement of engineering solutions within their projects.
