CA 2270770

The invention concerns a caring doctor blade for a paperboard machine, which blade comprises layers of fibreglass and carbon fibre and a caring layer as a rigid laminated structure, which caring layer comprises carbon fibres and grinding particles in direct vicinity of the carbon fibres. The orientation of the fibreglass layers is parallel to the longitudinal axis of the blade, and at least in some of the layers that contain carbon fibre the orientation of the carbon fibres is substantially diverging from the direction of the longitudinal axis of the blade. The invention also concerns a method for manufacture of a doctor blade for a paperboard machine by means of a pultrusion method.
