An arrangement for fabricating planar elements which may be stacked for producing predetermined surfaces and bodies. The planar elements have cross-sections corresponding to respective cross-sections of the surface to be constructed. The planar elements are formed by cutting them from plate-shaped material or sheet metal, and the cut-out elements are held to the parent sheet or plate material by tabs. The planar elements are cut successively from the sheet or plate-shaped material at spaced intervals. The cutting action is such as to leave the tabs for holding the planar elements in place. Registration holes are punched about the planar element, so that these may be readily stacked relative to each other, as required to form the surface to be constructed. Sprocket holes are also punched in the sheet material to advance the material along a processing path at which the various processing stations are located. After a blank together with the cut planar element is cut or punched out from the plate or sheet material, the blank is stacked with other blanks, and the tabs are severed to remove the stacked planar elements from the remaining portions of the blanks. Adhesive is applied to selected areas of the planar elements and/or blanks to result in easy removal of the planar elements from the remaining blank material.
