Abstract
Abstract 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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
217 words
A method for producing planar elements for construction of a surface, comprising the steps of: feeding material with substantially parallel surfaces into a processing path; applying at least one reference location hole through said material within a predetermined area of said material for registering positions of planar elements relative to each other when stacked; cutting a predetermined contour through said material for subsequent removal of a predetermined planar element from said material; applying a cut through said material and spaced from said planar element for producing a blank carrying said planar element, said cut enclosing said planar element and having a closed cutting line; removing said blank from said material; collecting the material remaining after said blank has been removed, said contour being cut along a cut path in which tabs are left for supporting said planar elements, said tabs connecting said planar element to said blank; stacking blanks in predetermined relationship to each other through registration of said reference location hole; and severing said tabs after stacking said blanks for separating the planar elements from the blanks to form said surface of stacked elements, said reference location hole being applied before said planar element and blank are detached from said material, said planar elements being stacked to a depth dependent on the characteristics of said surface.
Claim 2
Independent Claim
217 words
A method for producing planar elements for construction of a surface, comprising the steps of: feeding material with substantially parallel surfaces into a processing path; applying at least one reference location hole through said material within a predetermined area of said material for registering positions of planar elements relative to each other when stacked; cutting a predetermined contour through said material for subsequent removal of a predetermined planar element from said material; applying a cut through said material and spaced from said planar element for producing a blank carrying said planar element, said cut enclosing said planar element and having a closed cutting line; removing said blank from said material; collecting the material remaining after said blank has been removed, said contour being cut along a cut path in which tabs are left for supporting said planar elements, said tabs connecting said planar element to said blank; stacking blanks in predetermined relationship to each other through registration of said reference location hole; and severing said tabs after stacking said blanks for separating the planar elements from the blanks to form said surface of stacked elements, said reference location hole being applied before said planar element and blank are detached from said material, said planar elements being stacked to a depth dependent on the characteristics of said surface.
