Abstract
A travelling slot cutting machine and method of cutting a workpiece upon the machine in which there are two independently operable and longitudinally aligned, endless conveyor belts, the adjacent ends of which are spaced apart to define a gap through which a cutting medium may be directed. To cut a workpiece supported over the gap, the cutting medium is directed through the gap while the cutting machine, as well as the gap, are moved longitudinally relative to the stationary workpiece. In moving the gap, the conveyors are clamped against movement over their respective supporting rollers. The supporting rollers are then moved in such a fashion that the length of at least one of the conveyor belts is maintained unchanged as the workpiece is transported from the upper run of one of the conveyor belts to the upper run of the other conveyor belts.
