FIELD: printing industry.
SUBSTANCE: device for cleaning roller cylindrical surface consists of doctoring device rear comprising journals centering on the second axle parallel to the first axle; doctor knife, moved by doctoring device rear; bearings for rotating journals along the axle; a quantity of diaphragms disposed distantly along the second axle in such a way that they encircle bearings; therewith diaphragms comprise bushing parts fixed against bearings and encircling them, and peripheral parts fixed against stationary bearing base and encircling bushing parts. Note that diaphragms are flexible for ensuring back-and-forth motion of bushing parts and bearings along the second axle relatively to peripheral parts and stationary bearing base. The first drive turns doctoring device rear along the second axle in standby position with doctor knife pulled away from cylindrical surface and in load-bearing position with doctor knife advanced to the cylindrical surface. The second drive transmits back-and-forth motion to bearings along the second axle. Present device has for an object inventing a device excluding prospect of deterioration due to bearings axial movement.
EFFECT: inventing a device excluding prospect of deterioration due to bearings axial movement.
