Abstract (en)

[origin: US4907631A] A cylindrical cutter head comprises a cutter head body having a cylindrical surface which is centered on an axis and which is formed with a plurality of radially outwardly open main grooves extending parallel to the axis and each having relative to a normal direction of rotation of the body about the axis a leading flank and a trailing flank. These flanks are generally planar and converge radially outward. A disposable knife blade in each of the grooves is pressed against the trailing flank thereof by an outwardly tapered centrifugal wedge braced radially between the blade and the leading flank. Each groove is formed immediately forward of its trailing flank with a radially inwardly projecting groove extension. Thus wide regrindable blades can be fitted in the groove with their rear edges seated in the respective groove extensions.
