IN AN APPARATUS FOR MANUFACTURING SHAPED ARTICLES WITH PREDETERMINED OUTLINE FROM ELASTICALLY DEFORMABLE WORKPIECES OF THE TYPE HAVING TWO OPPOSED SURFACES AND A PERIPHERAL FACE INTERMEDIATE SUCH SURFACES, IN COMBINATION, A FEMALE DIE HAVING AT LEAST ONE OPENING WHOSE OUTLINE CORRESPONDS TO THE DESIRED OUTLINE OF THE ARTICLE AND HAVING A FLAT SURFACE WHICH SUPPORTS ONE SURFACE OF THE WORKPIECE IN SUCH A WAY THAT SAID ONE SURFACE OF THE WORKPIECE COVERS SAID OPENING; DEFORMING MEANS FOR APPLYING CONSTANT PRESSURE OF UNCHANGING MAGNITUDE TO THE OTHER SURFACE OF THE WORKPIECE WHEREBY THAT PORTION OF THE WORKPIECE WHICH COVERS SAID OPENING YIELDS AND PENETRATES INTO THE INTERIOR OF SAID DIE; AND CUTTER MEANS FOR FORMING A SLIT IN THE PERIPHERAL FACE AND IN A CUTTING PLANE LOCATED BETWEEN THE SURFACES OF THE WORKPIECE PARALLEL TO SAID FLAT SURFACE OF SAID DIE WHILE THAT PORTION OF THE WORKPIEE WHICH COVERS SAID OPENING PENETRATES INTO SAID DIE WHEREBY THE WORKPIECE IS SUBDIVIDED INTO A PAIR OF SECTIONS THE FIRST OF WHICH HAS SAID ONE SURFACE AND AN ADDITIONAL SURFACE LOCATED OPPOSITE SAID ONE SURFACE AND PROVIDED WITH A PROJECTION WHOSE OUTLINE CORRESPONDS TO THE OUTLINE OF SAID OPENING, AND THE SECOND OF WHICH HAS SAID OTHER SURFACE AND A SECOND SURFACE LOCATED OPPOSITE SAID OTHER SURFACE AND PROVIDED WITH A CAVITY WHICH IS COMPLEMENTARY TO SAID PROJECTION, SAID DEFORMING MEANS COMPRISING A ROLLER OF CONSTANT DIAMETER HAVING AN AXIS OF ROTATION PARALLEL WITH THE PLANE OF SAID SLIT.

Claim 3
Dependent Claim
203 words
IN A PROCESS FOR MANUFACTURING SHAPED ARTICLES WITH PREDETERMINED OUTLINE FROM ELASTICALLY DEFORMABLE WORKPIECES OF THE TYPE HAVING TWO OPPOSED SURFACES AND A PERIPHERAL FACE INTERMEDIATE SUCH SURFACES, THE STEPS OF APPLYING CONSTANT PRESSURE OF UNCHANGING MAGNITUDE TO ONE SURFACE OF A WORKPIECE AND PERMITTING THE OTHER SURFACE TO YIELD TO SUCH CONSTANT PRESSURE WITHIN AN OUTLINE WHICH CORRESPONDS TO THE DESIRED OUTLINE OF THE ARTICLE; SLITTING THE WORKPIECE BY FORMING IN THE PERIPHERAL FACE THEREOF A CUT WHICH DIVIDES THE WORKPIECE INTO A PAIR OF SECTIONS THE FIRST OF WHICH HAS SAID ONE SURFACE AND A SECOND SURFACE LOCATED OPPOSITE SAID ONE SURFACE AND PROVIDED WITH A CAVITY, AND THE SECOND OF WHICH HAS SAID OTHER SURFACE AND AN ADDITIONAL SURFACE LOCATED OPPOSITE SAID OTHER SURFACE AND PROVIDED WITH A PROJECTION WHICH IS COMPLEMENTARY TO SAID CAVITY AND WHOSE OUTLINE CORRESPONDS TO THE DESIRED OUTLINE OF THE ARTICLE; APPLYING CONSTANT PRESSURE OF UNCHANGING MAGNITUDE TO SAID OTHER SURFACE OF SAID SECOND SECTION AND SIMULTANEOUSLY PERMITTING SAID PROJECTION TO YIELD TO SUCH CONSTANT PRESSURE; AND FORMING A CUT IN THE PLANE OF SAID ADDITIONAL SURFACE TO SEPARATE SAID PROJECTION AND A PORTION OF THE REMAINDER OF SAID SECOND SECTION FROM SAID SECOND SECTION.
