Definitions

  • the invention relates to a method for producing coins or tokens which have a coding made of ferromagnetic material particles in non-magnetic metallic materials.
  • Coding coins is intended to improve their machine security.
  • the increase in the price of all services has resulted in goods and service transactions being increasingly carried out using automatic machines, with the value of individual transactions constantly increasing at the same time.
  • the incentive grows alsifikate to the vending machine fraud by F, on the other hand, the demand for better security machines of the coins.
  • coin production it must be taken into account that this is a decidedly mass production, with quantities of 1 million per day or even more being expected.
  • certain specifications of coin production must be observed, such as that coin blanks must be punched out of rolled strip material, knurled and soft-annealed before being minted. There are also a number of work steps for surface treatment.
  • the introduced material particles or particles made of ferromagnetic materials must have a certain size in order to arrive at usable signals with an economically justifiable test effort. It is also readily apparent that the coding must remain reliable throughout the life of the coins, i.e. over periods of several - decades.
  • DE-OS 26 44 018 does not provide a sufficiently specific teaching on technical action, that the person skilled in the art will find the basic idea of a magnetically testable coin here, but not information, such as just one of those there mentioned variants could be realized with success.
  • All manufacturing steps, including the production of wire sections, are expediently carried out in a coin punching device using a follow-on tool.
  • the diameter of the holes should not be less than the thickness of the tape. In this way, one or more ferromagnetic particles can be introduced into the coin blanks.
  • a punching device with a multiple follow-up tool is used.
  • a strip of non-magnetic coin metal and the required number of wires made of ferromagnetic material are fed to the punching device in cycles.
  • An alloy with essentially 75% copper and 25% nickel is preferably used for the strips, while the wires consist essentially of nickel.
  • the invention proposes a method which is suitable for the large-scale mass production of coded coin blanks.
  • the process can, of course, with the precision to perform, the more closely for setting acceptance tolerances in the D ecodier Anlagenen required.
  • the process has the advantage that similar coins cannot be produced in any other way, and that the process for producing falsified products is comparatively complex and therefore uninteresting.
  • the edge of the coin is generally compressed by a knurling device, followed by soft annealing of the coin blanks in preparation for minting.
  • this annealing can be used and controlled in such a way that not only is the low hardness required for the embossing achieved, but also, if necessary, diffusion between the base material and the riveted material made of ferromagnetic material, which further improves their integration into the base material.
  • a layer material known per se in the method for coding coins as a band for coin production, which in addition to layers made of non-magnetic material has at least one continuous layer made of ferromagnetic material.
  • a three-layer material is expediently used in which the inner core layer consists of ferromagnetic material.
  • the laminate property or the coding or both properties use them for testing.
  • the attached photo shows an enlarged micrograph of a vertical section through a coin coded according to the invention, the darker areas on the left and right edge of the picture belonging to the non-magnetic coin metal, while the lighter area in the center of the picture shows the riveted ferromagnetic material. It can be clearly seen that the latter is seamlessly embedded in the coin metal and that the embossing on the top of the micrograph is perfectly formed in the transition area.
