Definitions

  • ABSTRACT A method in the manufacture of coins, medals and like objects from plated material, the method including the steps of forming from the plated material discs having an extension which exceeds the extension of the blanks used in the embossing operation, recessing the peripheral edge surface of each disc so that the outer layer of the disc projects beyond the central layer thereof, folding the outwardly projecting portions of the outer layers of each disc toward each other, the recess being made sufficiently large so that the said inwardly folded portions at least approximately reach each other, and embossing the resulting blanks to form coins or like objects.
  • the present invention relates to a method for manufacturing coins or like objects of plated material.
  • the object of the present invention is to provide a novel and improved method for manufacturing in preference coins, by means of which coins or the like which satisfy the high demands placed on the appearance of said coins can be manufactured in a simple and economic manner despite the use of relatively inexpensive starting material.
  • the invention also relates to coins or like objects manufactured in accordance to the new method.
  • FIG. 1 shows diagrammatically the various stages in manufacturing a coin in accordance with the invention
  • FIG. 2 shows a perspective view of a coin manufactured in accordance with the invention and from which a sector-shaped portion has been cut away.
  • the reference numeral shows in cross section a portion of plated material in the form of a disc or strip and having two outer layers 11, comprising for example a copper alloy embodying percent Ni and an intermediate layer 12, comprising for instance a copper alloy embodying 3 percent Ni.
  • a disc 14 is formed from this material, for example by punching along the lines 13.
  • the disc 14 has an extension which exceeds that of the blank used in the embossing operation, while the outer contours of the disc are suitably adapted to the outer contours of the coin or like article to be manufactured, e.g., being circular for a circular coin or hexagonal for an hexagonal coin etc.
  • the peripheral edge surface 15 of the disc 14 is then recessed, as shown at 16, so that the outer layers 11 of the disc 14 project beyond the central layer 12 thereof, to form projecting portions 17.
  • the portions 17 of each disc 14 are then folded in towards each other.
  • the recess 16 is made sufficiently large to permit the folded-in portions to at least reach each other.
  • the folded portions either fall slightly short of each other or somewhat overlap each other, it is preferred that the portions 17 when folded in towards each other come into exact edge to edge contact.
  • the portions 17 are suitably folded by means of automatically operating machines and folding can, to advantage, be effected in one or more working stages by bringing pressure rollers to bear against the portions 17 during rotation of the discs 14.
  • the resulting blank 18 can be embossed in a conventional manner to form a coin l9 presenting a peripheral edge 20 which covers the material of the intermediate layer 12 and in which the oints between the portion 17 rs invisible, at least to the naked eye.
  • the material of the layers 11 and 12 will spread slightly during the embossing operation to fill out any cavities 21 remaining after folding the portions 17.
  • the recess 16 in FIG. 1 has been shown to have a semicircular cross section this is not restrictive to the invention.
  • the recess 16 may have a V-shaped cross section or the shape of a frustated cone. in the manner illustrated, the recess at the surface 15 of the disc 14 can extend exactly to the outer layers. It is, however, also possible to make the recess so wide that a certain portion of the material of the outer layers 11 is removed, or to make the recess 16 so narrow that the portion 17 will also contain a portion of the material of the intermediate layer.
  • the recess can be more or less eccentric, for example so that one portion 17 projects further than the other, and also that the disc 14 presents more than three layers.
  • Other modifications can of course be made within the scope of the invention as it is defined in the following claims.
