A sanding tool is adapted to be attached to an existing wood board molding machine. The sanding tool provides a rotating sanding drum which removes imperfections from the profile of the molding as it exits the molding machine. The sanding drum is height adjustable and is powered by an electric motor.

A processing element for processing a profile-shaped or flat metallic workpiece, with the processing element designed such that a plurality of similar processing elements can be arranged one behind the other on a supporting device in the longitudinal direction of the supporting device, the supporting device can be driven in a circulating manner and the plurality of processing elements can be guided past the workpiece for surface processing at least approximately linearly by means of the supporting device. A rectangular or block-shaped main body having bearing surfaces for bearing on the supporting device is provided, and oblong ribs protruding outward in a web-like manner are provided on the main body on opposite flat longitudinal sides and overlap the corresponding opposite flat longitudinal sides of the main body on an identically embodied processing element, which is arranged between the ribs.

A rotary tool containing a core hub with helical groove on its outer surface filled in with continuous abrasive filament formed by folding of a pre-cut abrasive sheet including multiple bristle like straps extending radially from the hub. The method of manufacturing includes the steps of providing a hub, and forming a helical groove with inverted V-shaped cross-section along its cylindrical surface. An abrasive element is wound around the hub so that the folded edge is fed in the V-grove and is buckled inside the groove providing, along with securing it by sufficient pre-tension of the abrasive element, a secure anchoring of the abrasive element through locking of the buckled edge. The abrasive filament is formed from a roll of abrasive cloth as one continuous piece using a cutting operation and is provided with center-line perforations. These perforations assist folding the filament by providing it with discrete and desired flexibility as well as weakening it in such way that it assists the process of folded edge buckling inside the groove during winding and therefore forms a tight anchoring junction with the hub without need for an adhesive.
