Title: The Innovations of Harald Aufrecht
Introduction
Harald Aufrecht is a notable inventor based in Aalen, Germany, recognized for his contributions to the field of papermaking machinery. With a total of six patents to his name, Aufrecht has developed innovative solutions that enhance the efficiency and durability of press devices used in the industry.
Latest Patents
One of Aufrecht's latest patents is the "Extended nip press blanket." This invention is designed for extracting water from a web in the press nip of a papermaking machine. It features an elastomeric matrix, where the outer area is thermally treated to increase wear-resistance. This design ensures that the outer area, which faces greater stresses, exhibits enhanced durability. The press blanket is produced in a single operation by casting a hot-casting elastomeric matrix onto a cylindrical mold, while reinforcing threads are integrated into the material. The selective thermal treatment achieves increased wear-resistance at the outer surface, extending below the depth of grooves or bores.
Another significant patent is the "Surface contoured press jacket for a shoe press." This press jacket consists of an elastomeric material with two layers of reinforcement threads. The inner layer comprises longitudinal threads that extend parallel to the axis of rotation during operation, while the outer layer consists of fabric or circumferential threads wound helically. The inner surface of the press jacket features longitudinal grooves that enhance its functionality. Various techniques for forming these grooves are described, including enlarging the longitudinal threads and deforming the jacket material around the threads.
