Abstract (en)

[origin: WO9937863A1] A rail-mounted surface-machining tool has a frame (1) for supporting a number of pressure rollers (7) and means for vertically adjusting the pressure rollers (7). The pressure rollers (7) are arranged in two parallel rows which are perpendicular to the rails and overlap in their range of action. The pressure rollers (7) are mounted on a holder (6) which can swivel about an axis of oscillation (8) of the pressure rollers and whose swivelling range can be limited on the supporting frame (1). The pressure rollers (7) are vertically movable in a setting range E in a roller bearing on the holder (6). The advantage of this device is that the pressure exercised by the pressure rollers (7) on the front or opposite side can be varied, enabling a grit coating to be anchored, for example in a mastic asphalt mass, in a much more easily controlled manner. Surfaces with strong slopes can also be more easily processed and guidance on the rails is improved.
