<p>Disclosed is a grinding head (1’) adapted to rotate about a central axis, having a surface (2’) selected between a plane surface and a cylindrical surface, and which is provided with retainer grooves for edge profile parts (14) of a number of abrasive paper members (3) with associated support brushes (4), wherein the abrasive paper members (3) are mounted at an angle of 20-40°, preferably about 30°, directed obliquely forward in the direction of rotation of the plane surface (2’) and the tangential plane of the cylindrical surface, respectively, wherein the retainer grooves (12) for the edge profile parts (14) of the abrasive paper members (3) extends obliquely rearwards in the direction of rotation of the plane surface (2’) at an angle (8) of 3-10° relative to a radial extension, or wherein the retainer grooves (12) of the edge profile parts (14) of the abrasive paper members (3) extend obliquely rearwards in the direction of rotation of the cylindrical surface (13) at an angle of 3-10° relative to an axially parallel generatrix of the cylindrical surface (13). In a simple way is hereby readily achieved a more optimal abrading of particularly outer side edges and edge areas of plate-shaped items.</p> |
