Abstract (en)
[origin: EP0765697A1] The appts. incorporates several cup-shaped rotating grinding tools(1) which are distributed over the roll length. Together with their carriers they can oscillate parallel to the roll axis, and are pressure-adjustable perpendicular to this axis. Each tool is carried at the end of a grinding spindle installed in a sleeve (8) which is connected to the tool drive elements. The sleeve (8) is tubular and coaxially surrounds a driven grinding sleeve (6). The grinding sleeve accommodates the axially movable but rotationally keyed grinding spindle (3). The grinding spindle is connected to a drive (21) which serves for its limited axial displacement (4), and is carried by the sleeve (8).
