摘要 |
Coins and medals are constructed from a ring having an inner opening and an insert disposed inside the opening, the insert comprising a groove to be filled with material of the ring plastically deformed, the ring having an inner wall substantially smooth and vertical, having an initial thickness which is greater than the initial thickness of the insert and having a cross-sectional shape which is substantially trapezoidal, a small base of the trapezoid constituting the inner wall of the ring, thereby providing a plastic deformation of the material of the ring towards the insert for connecting the ring with the insert. |
