Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method of manufacturing an accessory material having a unique shape and structure by twisting ribbon-shaped metal strips such as gold.

[Prior art] Traditional accessories such as bracelets and necklaces made of gold chains are expensive and heavy due to their shape and structure, and their surface area is limited, resulting in low reflection and lack of shine. It was hot.

[Problems to be Solved by the Invention] The present invention was developed as a material for accessories such as bracelets, necklaces, etc., which can be used as a lightweight substitute for chains, can reduce costs, have a large surface area, and have high reflective efficiency.

[Means for Solving the Problems] The present invention is a means adopted to achieve the above-mentioned object, in which metal strips 1 and 2 made of gold or the like are overlapped and one end portion 3 is fixed by appropriate means. Other end 4
are meshed with the rotating device 5 and twisted in one direction, and the fixed ends of the overlapped and twisted metal strips 1 and 2 are peeled off from side to side while being rotated in the opposite direction again. At the same time, the two spiral metal strips are twisted together in the opposite direction, and the two spiral metal strips are twisted together in the opposite direction. The troughs 6 and crests 7 of the spiral are bent in opposite directions while shifting slightly, and are twisted back to back with extreme protrusion, and then one is fixed again and the other is slightly stretched while rotating in the opposite direction. This method of manufacturing an accessory material includes a step of shaping the openings of the side edges 8, which are slightly different from each other, by bringing them into close contact with each other.

[Function] The present invention consists of a method as described above, in which metal strips 1 and 2 of gold or the like cut in advance into ribbon-like lengths are overlapped, one end 3 is fixed by an appropriate means, and the other is fixed. The end portions 4 are engaged with the rotating device 5, rotated in one direction to twist them together, and the fixed ends of the overlapped metal strips 1 and 2 are again rotated in the opposite direction and peeled off from side to side. The spiral metal strips of the book are peeled off to reach the fixed base, and at the same time, if you continue twisting while giving rotation in the same direction, the two spiral metal strips will shift slightly from each other and each spiral. The valleys 6 and peaks 7 are bent in opposite directions to make them extremely protruding, and then twisted back to back, and by fixing one side again and slightly stretching the other, they are slightly offset from each other, and each side edge 8 is shifted to form a mouth. This is a method of manufacturing accessory materials that can be shaped by fitting open parts.

[Example] An example of the present invention will be described based on the drawings.
Figure 1 shows flat rectangular metal strips 1 and 2 made of gold or the like that have been cut into a ribbon shape in advance to an appropriate length, stacked one on top of the other, and one end 3
Fix it by appropriate means such as pinching it with pliers etc.
The other end 4 is engaged with the chuck of the rotating device 5, etc.
This shows the process of rotating in one direction and twisting once.

FIG. 2 is a perspective view of the metal strips 1 and 2 which are overlapped and twisted together.

FIG. 3 shows that one fixed end of the metal strips 1 and 2 twisted together in the above process is fixed again to the chuck of another rotating device 9, and while rotating in the opposite direction, the metal strips 1 and 2 are peeled off from side to side. It shows the process of forming a spiral metal strip.

FIG. 4 is a perspective view showing the metal strip in a state where it is peeled off from side to side.

Figure 5 shows that at the same time as it is peeled off and reaches the root,
The two spiral metal strips 1 and 2 twisted in opposite directions are twisted while being rotated in the same direction, and the troughs 6 and peaks 7 of each spiral are bent in opposite directions as the two spiral metal strips 1 and 2 are slightly shifted from each other. This shows the process in which the fibers are twisted back to back at each side edge 8 so that the fibers protrude to an extreme extent.

FIG. 6 is a perspective view showing a state in which the spiral metal strips are twisted together again.

Fig. 7 shows that by fixing one side again and applying reverse rotation with a rotating device to loosen the twist a little and stretching it to the other side, the twists are slightly different from each other and each side edge 8 is shifted so that the mouth is open. FIG. 3 is a perspective view showing a state in which the curved sides are brought into close contact with each other and shaped.

FIG. 8 shows a completed diagram of a product in which the material produced by the above process is formed into a large number of ring shapes, which are connected together.

[Effects of the Invention] The present invention consists of a method as described in the above-mentioned embodiments, and includes a bracelet made of a conventional gold chain, etc.
Accessory materials such as netskures are determined by their shape,
The structure was heavy and costly, and the surface area was limited, so there was little reflection and lacked shine, but the present invention replaces it with a chain such as a bracelet or netcle, making it lighter and lowering costs. This is an extremely excellent invention for a method of manufacturing an accessory material that is polygonal, has a large surface area, and has high reflection efficiency.

Claims (1)

[Claims] 1 Overlap metal strips 1 and 2 such as gold, one end 3
is fixed by appropriate means, and the other end 4 is fixed by a rotating device 5.
The process involves meshing the metal strips 1 and 2 with each other and rotating them in one direction to twist them once, and then rotating the fixed ends of the metal strips 1 and 2 in the opposite direction again and peeling them off from side to side to form two pieces. The process of creating a spiral metal strip, and the process of peeling it off and reaching the root, and at the same time continuing to twist it while giving rotation in the opposite direction, twisting it in the opposite direction, the two spiral metal strips gradually intertwine with each other. The troughs 6 and peaks 7 of the spiral are bent in opposite directions while being shifted, and are twisted back to back with extreme protrusion, and again, one is fixed and rotated in the opposite direction while the other is slightly stretched, so that they are slightly offset from each other. The method for manufacturing an accessory material comprises the step of shaping the misaligned openings of each of the side edges 8 to make them come into close contact with each other.
