DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIGS. 1 to 5, the present invention largely comprises a cutting step S100, a rolling step S200, a ring forming step S300, and a polishing step S400.

Accordingly, the cutting step S100 is formed so as to cut the gold strip according to the predetermined interval from the gold (Au) plate having elasticity and ductility.

At this time, it is preferable that the gold plate has a design such as a pattern on one side or both sides, and it is preferably formed of a thin plate of about 1 to 5 mm.

This is because, in addition to cutting the gold band from the gold plate, the pattern is engraved in advance, so that it is possible to form a ring as quickly as a semi-finished product, and it is much more workable than a method of stamping a design (design pattern) This is a convenient feature.

It is also possible that the above-mentioned gold plate is rolled by superimposing two color (such as yellow gold, platinum or pink red gold), rolled, and integrated into a gold strip.

It has the characteristic that it can guarantee the diversity of the ring and provide a different aesthetic feeling.

Then, the rolling step S200 is performed to insert the cut gold strip into the curved jig 100, and then press the shaft 210 of the up-down press 200 so that the flat gold strip is curved do.

That is, in the pivoting or swing type structure, the upper mold having the jig grooves can move in one direction or the other direction seesaw motion using the rotary shaft as a hinge, so that the worker can move the jiggroove left and right with respect to the pressing axis, This is formed so that a straight line-shaped gold band is more closely adhered to the inner circumference arc shape of the jig groove, and a circular shape can be formed.

That is, the cross-sectional groove is formed to be able to select one of cross-sections of, for example, a quadrangle, a trapezoid, an ellipse, and other geometric curves so as to provide various products for casting ring processing.

Such a cross-sectional groove may be formed as a separate frame from the jig groove to facilitate exchange of the same.

Then, in the ring forming step (S300), both ends of a semicircular, parabolic, or arc-shaped gold strip are fused (soldered) with the same gold material to form a ring shape.

That is, the ring of the alphabet 'C', which is near the circle, can be easily and easily fused at both ends by hand so that a simple preparation can be provided.

Thereafter, in the polishing step (S400), the connecting portion of the ring is fusion-bonded (soldered) and polished so as to have a beautiful outer circumferential surface.

That is, at the time of polishing, the surface is smoothly provided using surface sandpaper or the like by high-speed rotation.

That is, the embedding step allows the jewelery such as cubic, diamond, ruby, and sapphire to be seated, and it is preferable that the embroidering is fixed by fusion.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
