Title: Rudolf Kellersohn: Innovator in Polymer Processing
Introduction
Rudolf Kellersohn is a notable inventor based in Hamminkeln, Germany. He has made significant contributions to the field of polymer processing, particularly in the production of extrudates and thermoplastic welding techniques. With a total of 2 patents, Kellersohn's work has had a lasting impact on the industry.
Latest Patents
Kellersohn's latest patents include a "Process and device for producing extrudates from ultra-high molecular weight polyethylene." This innovation allows for the processing of pulverulent or finely divided ultra-high molecular weight polyethylene on single screw extruders. By utilizing a screw with a specific geometry, the thermal degradation of the polymer into low molecular weight products is effectively avoided. The resulting profiles exhibit perfect surfaces, are free of voids and pores, and possess no internal stresses.
Another significant patent is the "Method for heated tool butt welding of tube and pipe of thermoplastic." This method involves placing the surfaces of thermoplastic pipes into contact with a heated tool to form an inner weld bead. The surfaces are then heated at a reduced contact pressure to the welding temperature, followed by fitting the surfaces together under pressure after removing the heated tool. An improvement in this method minimizes the formation of protrusions within the resultant pipes by pressing an elastic insert against the inner weld bead during the joining process.
