Abstract (en)
[origin: EP0129155A2] The apparatus for calibrating granite, marble, and the like in slab form, comprises a base frame on which a carpet conveyor (2) for transporting slabs (40) to be calibrated is caused to run and carries a calibrating head (10) which is movable perpendicularly to the plane of lay of the slabs (40). The calibrating head (10) includes a calibrating roller (20) driven rotatively about its own axis and having its axis substantially parallel to the plane of lay of said slabs (40) and substantially perpendicular to the direction of advance of the slabs (40). Furthermore an abrasive form (30), provided on the lateral surface of said roller (20), extends unbroken around the roller (20) into a substantially helical pattern.
