ABSTRACT:
This invention relates to apparatus for cutting or shaping material, as by heat-shaping, wherein the outline of a predetermined pattern is copied on the material which is to be worked on by following the pattern with a follower member whose movement is used to control a cutting or heat-shaping tool.
A vertically-arranged copying panel to receive the pattern is provided with two horizontal rails and a support which is movable along said rails. The follower member and the tool are mounted on the support and movable in vertical and horizontal directions, respectively, with respect to the support, and the support is movable across the copying panel and material worked on.
