圧嵌状態が製品において得られなくなり、該ボビ
ンの使用中糸止めを有効に行い得なくなる。 In conventional wooden sewing thread bobbins, the end of the thread is inserted into a diagonal notch in the flange of the bobbin. A flange for holding the end of the thread in a plastic bobbin is molded separately from the bobbin body, and then the cylindrical part of the flange is
It is known to be press-fitted into the cylindrical portion of the bobbin body and sandwiched between the flange of the bobbin. A so-called undercut is provided on the inner periphery of the cylinder mouth of the bobbin body to create a press-fit state between the thread stopper flange and the bobbin body, but when the mold is shaped, the shape of the undercut collapses. A press-fit state cannot be obtained in the product, and the thread cannot be effectively secured during use of the bobbin.
本発明は上記欠点を解消することを目的とする
ものである。 The present invention aims to eliminate the above-mentioned drawbacks.

い。 According to the method of the present invention, there is no difficulty in forming the undercut portion using a synthetic resin injection mold, and the locking collar 4 portion of the bobbin body and the locked portion 6a of the thread stopper flange body 6 are enlarged and It can be configured reliably. Furthermore, after molding the intermediate product shown in FIG. 2 using the same material, the product is completed by press-fitting the thread stopper flange body 6 into the protruding cylindrical portion 5 of the bobbin body 1 shortly after polymerization. If this is done, the workability is good, but it goes without saying that the press-fitting may be carried out some time after polymerization.
このようにしてえられた糸止め付き糸ボビン
は、第１図の例について説明したとおり、従来に
見ない高い品質でかつ価格低廉に提供し得るもの
である。 The thread bobbin with a thread stopper obtained in this manner can be provided at a low price and of a high quality never seen before, as explained in connection with the example shown in FIG.
