Machine-protection method for protecting machine elements in a continuously working press during production of sheets of material lightens roller presses to avoid damage to the surfaces of compaction rollers

摘要

Super-proportional increases in pressure can be registered through faulty spillages or foreign matter not crushed like lumps of glue. Roller presses can be lightened so as to avoid damage to the surfaces of compaction rollers (5,6). If an installation is stopped after registering an non-crushed defective spot or a doubling of matting, then that part of the mat of material to be pressed (8) and unable to be compacted satisfactorily is disposed of in a dumping bin by a reserve lift from a molding strap and by reversing a roller press. Independent claims are also included for the following: (1) A unit for protecting machine elements in a continuously working press during production of sheets of material; (2) A device for leveling or neutralizing above-average increases in thickness in a mat of material to be pressed before intake into a continuously working press during the production of sheets of material.
