Stone ageing apparatus, has stone contacting devices movable perpendicular to stone transport direction

摘要

Stone-contacting devices (5) used to removal the edge fragments from the stones (2) are connected to a drive system (12) so that they are movable in a direction perpendicular to the stone transport direction. The stone-contacting devices are located above a conveyor (3) for transporting the stones. The stone-contacting devices comprise two or more parallel elongated blades (7) with curved cutting edges (8). The drive system comprises a cylinder arrangement (9).
