Abstract
A cantilevered transverse arm is mounted for movement along both a longitudinal and transverse axis. The outer end of the arm is adapted to be disposed over a metal slab to be cut and carries a tool assembly which is adjustable thereon. A guiding assembly is fixedly mounted to the arm and includes a pair of longitudinally spaced guide rollers positioned so that the cutting tool is disposed in a transverse plane extending between the rollers. Each roller is individually shiftable into and out of engagement with the slab edge. Initially, the leading roller is advanced toward the slab edge, while the trailing roller is retracted. The rollers are then moved toward the slab edge until the leading roller engages the said edge ahead of the slab corner. As the entire device moves longitudinally along the slab, the leading roller is retracted while the trailing roller moves into engagement with the slab edge. Deformed slab corners are thereby bypassed by the tool guidance system.
