【発明の詳細な説明】
（産業上の利用分野）
本発明は、指輪、ブローチ等に於いて、比較的大きな石
であるメインストーンの周囲に配設する極めて小粒な宝
石を取り付ける為の爪座の製造法に関する。Detailed Description of the Invention (Industrial Application Field) The present invention is a nail seat for attaching extremely small gemstones arranged around a relatively large main stone in rings, brooches, etc. Concerning the manufacturing method.
（従来の技術）
従来、この種の爪座の製造は、第２図に示す如く所要の
直径を有するリングＡの両側部に、別個に成形された爪
棒Ｂ、Ｂをろう付けする工程が採られていた。(Prior Art) Conventionally, the manufacturing of this type of claw seat involves the step of brazing separately formed claw bars B to both sides of a ring A having a required diameter, as shown in Fig. 2. It had been taken.
然し乍ら、リングＡの直径は１．７ｍｍ程度であり、且
つ爪棒Ｂ、Ｈの直径は０．７ｍｍ程度というように極め
て小さい為、これらのろう付は作業は著しく困難性を伴
うばかりてはなく、ろう付は部分の存在により装飾的美
観を損ねるという問題があった。However, the diameter of ring A is approximately 1.7 mm, and the diameter of claw bars B and H is approximately 0.7 mm, which are extremely small, so brazing these is not only extremely difficult but also difficult. , Brazing has a problem in that the presence of parts spoils the decorative beauty.

公報がある。）
（発明が解決しようとする課題）
ところで、上記の爪座の製造法は、パイプ材３に変形し
た金属板ｌの両側縁合致線４の部分のろう付けか、金属
板ｌの板厚が薄い為、厄介であり、強度も不十分である
。またろう付は線が直線にならないものである。その上
、最終的にリング７に爪座９を作った後で、リング７を
研摩して光沢を出すと、ろう付は跡が表れてきて装飾的
美観を損ねるものである。As a method of manufacturing a claw seat to solve this problem, as shown in FIG. As shown in the figure, the pipe is deformed into a pipe 3 having the required diameter, and the parts of the mating lines 4 on both sides of the metal plate 1 are brazed together with the deformation, and then a wire is drawn that is elliptical in plan and has claw seat molding parts at both ends. A material tube 6 integrally having claw bars 5 on both sides as shown in FIG. 3C is formed through the mold holes 2b, 2bt... (see FIG. 3a) of the plate 2, and then This raw material tube 6 is cut into a ring 7 having a required width as shown in FIG. There is a method of obtaining a pawl seat 9 of a predetermined shape as shown in FIG. 3e. (Japanese Unexamined Patent Application Publication No. 56-54802 is a prior art document.) (Problem to be Solved by the Invention) By the way, the above-mentioned method for manufacturing a claw seat is based on the method of manufacturing a metal plate l that has been transformed into a pipe material 3 by matching both side edges of the metal plate l. It is difficult to braze the wire 4 or because the metal plate 1 is thin, and the strength is insufficient. Also, brazing requires that the wires are not straight. Moreover, if the ring 7 is polished to make it shiny after the claw seat 9 is finally formed on the ring 7, traces of brazing will appear and spoil the decorative beauty.
そこで本発明は、ろう付けせずに小粒宝石取付用爪座を
作る方法を提供しようとするものである。Therefore, the present invention aims to provide a method for making a claw seat for attaching small jewels without brazing.

Next, this bottomed cylindrical body is press-molded to form claws at symmetrical positions on the outer periphery parallel to the axis center line, and then this bottomed cylindrical body with claws is formed into a ring with the required width. The ring is cut, and then the remaining upper edge of the ring excluding the claw portion is cut by a required amount to obtain a claw seat of a predetermined shape.
