METHOD FOR MONITORING SEALING ELEMENTS OF A FLUIDICALLY ACTUATED ROLLER ARRANGEMENT AND ROLLER ARRANGEMENT

摘要

The invention relates to a method and to a fluidically actuated roller (4, 19, 42), wherein pressurized actuating fluid is applied to sealing elements (11, 12, 28, 29, 47), the pressure of the actuating fluid being influenced by means of a pressure valve (17, 30, 48), and the volumetric flow of the actuating fluid through the pressure valve (17, 30, 48) being detected in order to detect the wear of the sealing elements (11, 12, 28, 29, 47).
