Title: The Innovative Contributions of Robert Lehmann
Introduction
Robert Lehmann is a notable inventor based in Gundelfingen, Germany. He has made significant contributions to the field of sealing technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and effectiveness of sealing processes in various applications.
Latest Patents
Lehmann's latest patents include a groundbreaking invention known as the sealing roll. This innovative sealing roll features a stationary internal shaft and an inductively heatable roll jacket that rotates around the shaft. A series of induction coils are wound around the shaft over ferrites, which are exposed to the outside. The design incorporates cables for the induction coils that are routed through a cable conduit in the shaft, allowing for connection to an external induction generator. Additionally, a water cooling channel is integrated into the shaft to indirectly cool the induction coils. A cavity is formed in at least an axial subsection of the sealing roll, where a temperature detection device is positioned to monitor the temperature of the roll jacket through an IR temperature sensor.
Another notable patent is the device for roll-sealing sheets. This device is designed to seal a formed bottom sheet and a lidding sheet between a feed roll and a sealing roll. It includes a heating unit that preheats the lidding sheet before sealing. The heating unit employs a contactless induction heating device, featuring coils and magnetic-field influencing elements arranged transversely to the travel direction of the lidding sheet. The distance between the magnetic-field influencing elements and the coils is adjustable by a control unit based on temperature sensor measurements, allowing for precise regulation of the temperature profile of the lidding sheet.
