<p>Pattern cutting of sheet metal is effected automatically. Cutter has conveyors which move a metal sheet into a pattern cutting position, the sheet being guided exactly into position. The sheet is clamped securely in pattern cutting position and a cutting tool begins cutting the pattern from the sheet. The cutting tool is movable in x, y, and a directions so that any type of pattern may be cut. Tool has a scissors-like shearer, one blade above the horizontal sheet being cut, and another blade below the sheet. Supporting tips are mounted on the conveyor to support the metal sheet in cutting position while preventing damage to the conveyor during cutting. A notcher is also provided movable along each side edge of the metal sheet the notchers being adjustable with respect to each other to accommodate sheets of different widths. The x, y, a, and notcher motors are all controlled by a computer.</p> |
