Abstract

Surface finishing or polishing rollers are made by successively mounting disk-shaped surface finishing elements on a spindle rotating in operation. The surface finishing elements are formed of a slitted, preferably rectangular sheet having a continuous portion of material with lamellae protruding perpendicularly therefrom. The slitted sheet is shape-fixed with binder, and the periphery of the protruding lamellae forms an ellipse. The surface finishing elements, each of which comprises an oval disk with lamellae, are mounted inclined on the shaft of the spindle so that the contour of the successively mounted surface finishing elements forms a cylinder in the axial direction of the spindle.

Claims

1. A method of making surface finishing or polishing rollers comprising disk-shaped surface finishing elements mounted successively on a spindle rotating in operation, each of said surface finishing elements being formed of a slitted, preferably rectangular sheet which has a portion of material continuous in one direction with lamellae protruding perpendicularly therefrom, characterized in that the slitted sheet is shape-fixed with binder by arranging the portion of material continuous in one direction over an oval mandrel where the periphery of the protruding lamellae therein forms an ellipse, and that a plurality of surface finishing elements, each comprising an oval disk with lamellae, are mounted inclined on the shaft of the spindle so that the contour of the successively mounted surface finishing elements is cylindrical in the axial direction of the spindle.

2. A surface finishing or polishing roller for use in the working of surfaces during which working the roller is simultaneously caused to rotate about a longitudinal axis thereof and to move in parallel with the surface being worked, characterized in that the surface finishing roller comprises a plurality of oval disk-shaped surface finishing elements (7) inclined about said longitudinal axis each of said finishing elements having an oval center ring and a plurality of lamellae extending outwardly therefrom.

3. A roller according to claim 2, characterized in that the individual elements (7) comprise oval, slitted surface finishing disks.

4. A roller as in one of claims 2 or 3, in which one side of the elements (7) is provided with abrasive.

5. A roller according to claim 4, characterized in that the successive elements (7) are mounted such that the sides provided with abrasive point in the same direction.

6. A roller according to claim 4, characterized in that the individual elements (7) are mounted on carrier disks (8) having one or more grooves to receive complementary guide fins in an axial direction on the surface of the roller (6, 22, 45).

7. A roller according to claim 4, characterized in that the shaft (1, 22) of the roller is formed with a polygonal cross-section.
