パ一部２２が設けられている。- The cone 2 is fitted inside or outside the wedge-shaped piece 15 at the end of the resin-coated metal tube 1 to be drawn, and its maximum diameter 21 is approximately equal to the inner diameter of the metal tube 11. or approximately equal to the outer diameter of the resin-coated metal tube 1, the length of the cone 2 is at least longer than the cut 13, and the wedge-shaped piece 15 of the synthetic resin-coated metal tube 1 is drawn. A tapered portion 22 is provided which is approximately equal to the pointed end 16 .
又、錐体２は合成樹脂被覆金属管１の尖状端部１６の内
側に嵌挿される場合には、中実、中空どちらであっても
よい。Furthermore, when the cone 2 is fitted inside the pointed end 16 of the synthetic resin-coated metal tube 1, it may be either solid or hollow.
尚、錐体２が合成樹脂被膜１２と相溶性のない樹脂から
作製されている場合には、錐体２に接着剤を塗布してお
くと好ましい。Note that if the cone 2 is made of a resin that is incompatible with the synthetic resin coating 12, it is preferable to apply an adhesive to the cone 2.
次に合成樹脂金属管１の楔形片１５を尖状端部１６に絞

図の如く尖状端部１６が水密化される。Next, in order to draw the wedge-shaped piece 15 of the synthetic resin metal tube 1 into a pointed end 16, first, the synthetic resin cone 2 is fitted inside the wedge-shaped piece 15, and the wedge-shaped piece 15 and the cone 2 are drawn. When pressurized while heating, the wedge-shaped piece 15 is made into a pointed shape, and the outer wall resin of the cone 2 melts from the cut 13 and the end face 1 of the wedge-shaped piece 15 is formed.
4 is fused and integrated with the synthetic resin coating 12 so as to cover the fourth
As shown, the pointed end 16 is made watertight.

形片１５が尖状端部１６に絞り加工される。Further, after pressurizing the wedge-shaped piece 15 of the synthetic resin-coated metal tube 1 to make the wedge-shaped piece 15 slightly pointed, the synthetic resin cone 2 is fitted onto the outside of the wedge-shaped piece 15, heated, and further pressurized. , the inner wall resin of the cone 2 extends from the cut 13 to the end surface 1 of the wedge-shaped piece 15.
The cone 2 is melted into the synthetic resin coated metal tube 1 so as to cover the cone 2.
The synthetic resin coating 12 is fused and integrated, and the wedge-shaped piece 15 is drawn into a pointed end 16 as shown in FIG.
