    • A MECHANICAL SPLICE FOR ROLLS OF METAL IN CONTINUOUS METAL FABRICATION WHEREIN EACH SPLICE INCLUDES A PORTION DEFORMED FROM ADJACENT SHEETS OF METAL THEREBY LIMITING RELATIVE MOVEMENT THEREBETWEEN. IN ONE EMBODIMENT, THE PORTION OF MATERIAL DEFORMED IS SPREAD AFTER IT IS DEFORMED TO PREVENT IT FROM RETURNING TO ITS ORIGINAL CONDITION. A DIE FOR PERFORMING THE DEFORMATION AND SPREAD INCLUDES A FLAT DIE SURFACE WITH OPPOSITELY OUTWARDLY FLARING END SURFACES WHICH PRESS SUPERIMPOSED PORTIONS OF THE SHEETS OF METAL INTO A DEPRESSION IN A SECOND DIE AGAINST A YIELDABLE PIN WHICH SPREADS AT LEAST ONE OF THE PORTIONS BY AT LEAST THE TIME THE MOVABLE DIE HAS BOTTOMED OUT BUT AFTER THE ONE PORTION IS DEFORMED OUT OF ITS SHEET OF MATERIAL. THE METHOD OF FORMING THE MECHANICAL SPILCING INVOLVES THE DEFORMING OF THE ELONGATED PORTION THEREBY FORMING AN OPENING IN THE SHEET OF MATERIAL AND THEN THE SPREADING OF THE DEFORMED PORTION SUCH THAT IT CANNOT PASS BACK INTO THE OPENING. THE SPREADING MAY BEGIN AT THE SAME TIME AS THE DEFORMING STEP BEGINS BUT IS NOT COMPLETED UNTIL THE DEFORMING STEP HAS BEEN COMPLETELY FINISHED. A SECOND EMBODIMENT OF THE APLICING INCLUDES SEMI ELIPTICAL PORTIONS THE MIROR IMAGE OF EACH OTHER ON OPPOSITE SIDE OF A PERPENDICULAR PLANE TO THE SHEETS OF MATERIAL BEING DEFORMED ON OPPOSITE SIDES OF A PARALLEL PLANE TO THE SHEETS OF MATERIAL TO LACK THE SHEEETS AGAINST RELATIVE MOVEMENT. THE DIES OF FOR FORMING THE SEMI ELIPTICAL DEFORMATIONS ARE THE MIROR IMAGE OF EACH OTHER AND HAVE CONVEX OUTER SURFACES WHEREBY THEY REGISTER WITH EACH OTHER.

    • A mechanical splice for rolls of metal in continuous metal fabrication wherein each splice includes a portion deformed from adjacent sheets of metal thereby limiting relative movement therebetween. In one embodiment, the portion of material deformed is spread after it is deformed to prevent it from returning to its original condition. A die for performing the deformation and spreading includes a flat die surface with oppositely outwardly flaring end surfaces which press superimposed portions of the sheets of metal into a depression in a second die against a yieldable pin which spreads at least one of the portions by at least the time the movable die has bottomed out but after the one portion is deformed out of its sheet of material. The method of forming the mechanical splicing involves the deforming of the elongated portion thereby forming an opening in the sheet of material and then the spreading of the deformed portion such that it cannot pass back into the opening. The spreading may begin at the same time as the deforming step begins but is not completed until the deforming step has been completely finished. A second embodiment of the splicing includes semielliptical portions the mirror image of each other on opposite sides of a perpendicular plane to the sheets of material being deformed on opposite sides of a parallel plane to the sheets of material to lock the sheets against relative movement. The dies for forming the semielliptical deformations are the mirror image of each other and have convex outer surfaces whereby they register with each other.
