Device for safeguarding or protecting against penetration by foreign bodies into a roller nip

摘要

A method for safeguarding against the entry of foreign bodies into a nip between two cylinders, which includes applying a deflection movement to one of the cylinders counter to a spring force applied thereto so as to overcome the spring force and, in accordance with a prescribed deflection distance, alternatively keeping the spring force to be overcome constant or reducing the spring force; and a device for performing the method.
