Abstract

A sanding device (1 ) comprising a core (10) and with a surface (20) having a plurality of bristles (12) and pieces of abrasive cloth (11) secured to it. According to the invention said pieces of abrasive cloth (11 ) being secured to said surface (20) by use of fastening elements (13) extending through said abrasive cloth (11 ) and into said core (10).

Abstract

The present invention relates to a machine for surface treatment, such as grinding or polishing, of a workpiece and comprises a rotating cylinder (1 , 19). On the cylindrical face, a number of grinding or polishing modules (17, 18) are provided that comprise hold-back means, preferably in the shape of brushes (13). The invention is characterised in that the brushes (13) extend outwards and forwards relative to the direction of rotation of the rotating cylinder. Hereby it is accomplished that, by a combination of the rotation of the cylinder and the movement of the workpiece in the direction of conveyance of the apparatus, the grinding means establish contact with the end face (101 ) on the workpiece (100) to the effect that grinding or polishing of the end face (101 ) is obtained.

Abstract

The invention relates to a brush module (1) for a rotating grinding brush for abrading essentially plane elements, said brush module (1) comprising: an elongate body part (10) with two opposed side edges (14,15) and a plurality of bristles that protrude from the body part (10) and are configured with at least one abrading cloth (8) with an abrasive side (9) that protrudes from the body part (10) essentially in the same direction as the bristles. The invention is characterised in that, at each of said side edges (14,15), an abrading cloth (8) is configured in such a way that the abrasive sides (9) of the abrading cloths (8) face in directions away from each other, whereby the abrasive side on each of said abrading cloths (8) will face in a direction towards the essentially flat element, irrespective of the direction of rotation of the grinding brush.

Abstract

The invention relates to a system of providing a structured surface on a preferably elongate, essentially flat workpiece (100) comprising at least one polymer surface, said system comprising a conveyor device with a plane of conveyance, wherein conveyor means for conveying said object in a direction of conveyance are configured in connection therewith, structuring means (4) having a direction of rotation following essentially the direction of conveyance and being configured above the plane of conveyance for providing the structured surface comprising a plurality of evenly distributed recesses. The system is particular by the structuring means (4) being configured for being moved sideways from side to side relative to the direction of conveyance when surface structure is imparted to the workpiece. The invention further relates to a method of providing a surface structure on a preferably elongate, essentially flat workpiece comprising at least one polymer surface.
