Abstract (en)
[origin: WO2021001226A1] The invention relates to a scraper device, associated with a contact surface, in particular a rotating roller (12), said scraper device having a scraper (11), provided for placement against the roller (12), for bringing the scraper (11) into contact with the roller (12) by means of a pressurized fluid, and having at least one sensor (13) provided on the scraper (11), by means of which sensor a measured value for the contact pressure of the scraper can be generated when said scraper (11) is placed against the roller (12). There is a control unit which controls the speed at which the scraper can be placed against the contact surface, in particular the roller (12).
