Abstract (en)
[origin: WO2021058166A1] The invention relates to a method for operating a shoe press, said shoe press having a shoe on which the radial inner surface of a press jacket slides. Lubricating fluid is introduced between the shoe and the press jacket for lubricating purposes, and the press jacket has at least one polymer layer into which a reinforcing structure is integrated, said reinforcing structure comprising at least one reinforcing thread. The lubricating fluid, the at least one polymer layer, and/or the at least one reinforcing thread is/are designed such that the lubricating fluid reaches the at least one reinforcing thread of the reinforcing structure and produces a color change in same in the event the polymer layer breaks. The invention also relates to a shoe press, to the use of a press jacket in such a shoe press, and to a machine comprising such a shoe press.
