Abstract
An improved cutting apparatus of the type comprising an endless roller conveyor (4) for carrying a moving strip (1), a carriage (9) located above the strip (1) and adapted to move in the same direction as the strip (1) and in the opposite direction and a thermal cutting device (12) carried by the carriage (9) and adapted to move transversally to the moving strip (1). The conveyor (4) is adapted to revolve in such way that its upper run continuously moves in the direction (X) of the strip (1) and the distance between the successive rollers (3) of the conveyor (4) is such that cutting can be performed without the rollers (3) being damaged. The apparatus can be used for cutting a continuously cast strip of anode copper into anodes (FIG. 1).
Claims15
An apparatus for thermally cutting a moving metallic strip into uniform pieces, which comprises:
- (a) a movable endless roller conveyor, the upper run of which carries the strip in a cutting zone, said conveyor being adapted to revolve in such a way that its upper run continuously moves in the same direction as the strip;
- (b) a carriage, located above the strip and adapted to move within said zone in the same direction as the strip and in the opposite direction;
- (c) means for coupling the carriage to the strip;
- (d) a thermal cutting device, carried by said carriage and adapted to move transversally to the travelling direction of the strip;
- (e) synchronization means for imparting to the endless roller conveyor a speed that is equal to that one of the strip;
- and
- (f) control means including first means for sensing the position of the conveyor rollers relative to the position of the carriage and adapted to sense a multiplicity of distinct relative positions, second means operable in response to said first means for increasing the speed of the endless roller conveyor until the cutting device reaches a position at a predetermined distance from one of the rolls of the roller conveyor, third means operable in response to said first means for lowering the speed of the endless roller conveyor until the cutting device reaches a position at a predetermined distance from one of the rolls of the roller conveyor, and fourth means operable in response to said first means for preventing operation of the cutting device when the latter is within a predetermined distance from one of the rolls of the roller conveyor, said second, third and fourth means being operable during the transverse movement of the cutting device.
