An apparatus for doctoring a cylindrical rotating surface, comprising a doctor back mounted for rotation about a first axis, and a blade carrier assembly mounted on the doctor back for rotation about a second parallel axis. A doctor blade is removably supported by the blade carrier assembly and is loaded against the rotating surface by a force applied to rotate the doctor back about the first axis. A liquid filled flexible walled tube extends along the second axis between the doctor back and the blade carrier assembly. The blade angle is adjusted by expanding and contracting the liquid filled tube to rotate the blade carrier about the second axis.
