<p>Pattern cutting of sheet metal is effected automatically, Conveyors 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 ? directions so that any type of pattern may be cut thereby. The tool may comprise a scissors-like shearer, one blade being provided above the horizontal sheet being cut, and another blade being disposed 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, ?, and notcher motors are all controlled by a computer. After pattern cutting, the conveyor is started up and the cut sheet transported away from the pattern cutting position, the pattern cut from the sheet being supported while the waste portions of the sheet fall into a waste bin or the like.</p> |
