Abstract
A caring doctor blade for a paper/board machine having layers of fiberglass and carbon fibers, and a caring layer as a rigid laminated structure, where the caring layer has carbon fibers and grinding particles in direct proximity to the carbon fibers. The orientation of the fiberglass layers is parallel to the longitudinal axis of the blade. At least some of the layers that contain carbon fibers. The orientation of the carbon fibers is substantially diverging from the direction of the longitudinal axis of the blade. A method for manufacturing the doctor blade for a paper/board machine by a pultrusion method is also disclosed.
