摘要

The invention relates to a doctor blade for the roll of a paper or board machine and a method for manufacturing the doctor blade. At least one fiber fabric (6a), having its fibers coated with hard particles prior to lamination, is supplied to the vicinity of that surface (4) of the blade which terminates in a cutting edge (2). The particle size is less than 30 μm. There are typically several fiberglass sheets coated with hard particles and the disposition thereof is such that in the vicinity of blade surfaces, at least in the vicinity of the surface (4) terminating in the cutting edge, the wear resistance is better than in the mid-section of a blade edge (3).
