ABSTRACT:
A device for cleaning a roll in a paper production plant has a doctor blade assigned to the surface of the roll. The doctor blade is mounted such that it can be pivoted with respect to the roll by two bearing journals that are aligned parallel to the axis of the roll. An actuating lever for pivoting the doctor blade is fixed to at least one of the two bearing journals. The bearing journal and the actuating lever are formed with mutually associated latching elements, by way of which the bearing journal and the actuating lever can be connected to each other in form-lock in different positions.
