０３部分がその他の部分よりも厚くなり、この厚
くなつた部分において補強材０２がチユーブ０１
に喰い込み、チユーブ０１の肉厚が相対的に薄く
なる。又、チユーブ０１の両縁（折り目０５）部
分の肉厚も相対的に薄くなる。(2) Structure of a conventional tube of this kind The structure of a tube of this kind in the past is shown in FIG. 1, and FIG. 2 shows a method for manufacturing the tube shown in FIG. A cylindrical reinforcing material 02 with a seam 03 created to form a piece of fabric into a cylindrical shape.
is inserted, and the two are adhered on the entire surface by the fusing action of the film 01 while being flatly pressed by a pressure roller 04. For this reason, in the conventional tube, as shown in Fig. 3, the pressure roller 0
4, when flat pressure welding, the joint 03 part of the reinforcing material 02 becomes thicker than the other parts, and in this thickened part, the reinforcing material 02 is attached to the tube 01.
The wall thickness of tube 01 becomes relatively thin. Further, the thickness of both edges (fold line 05) of the tube 01 is also relatively thin.
(3) 従来のチユーブの欠点
従来のチユーブは以上のように補強材の継ぎ目
部分及び両縁においてその肉厚が薄くなつている
ため、管路内の分岐部等において、第４図に示す
ように肉厚の薄い部分が流体圧の影響により膨大
化したり、肉厚の薄い部分にピンホールが発生し
たりするという欠点がある。(3) Disadvantages of conventional tubes As described above, the wall thickness of conventional tubes is thinner at the joints and both edges of the reinforcing material. However, there are disadvantages in that thin-walled portions may become enlarged due to the influence of fluid pressure, and pinholes may occur in thin-walled portions.
(4) 本考案の目的
本考案は、上記従来のチユーブの欠点を解消す
るため、チユーブと補強材との接着構造におい
て、チユーブの肉厚が局部的に薄くならない構造
を提案するのが目的である。(4) Purpose of the present invention The purpose of the present invention is to propose a structure in which the wall thickness of the tube is not locally thinned in the adhesive structure between the tube and the reinforcing material, in order to eliminate the above-mentioned drawbacks of the conventional tube. be.
(5) 本考案の構成
本考案は上記目的を達成するため、圧接ローラ
でチユーブと補強材を圧接する際に補強材の継ぎ
目部分とチユーブの両縁を逃れた位置において行
い、全面接着を行なわないようにした。なお、こ
の接着は上記条件を満足するならば要所において
スポツト的に行つてもよいし、連続した線状であ
つてもよい。(5) Structure of the present invention In order to achieve the above object, the present invention uses a pressure roller to press the tube and the reinforcing material at a position that avoids the joint of the reinforcing material and both edges of the tube, and performs full-surface adhesion. I tried not to. It should be noted that this adhesion may be done spot-wise at key points, or may be done in a continuous line, as long as the above conditions are satisfied.
(6) 本考案の作用及び効果
本考案は以上のように、チユーブと補強材とを
圧接する際に、補強材の継ぎ目及び両縁折り目部
分を逃れた位置において行なうようにしたので、
特に補強材側がチユーブに強く喰い込むことはな
く、チユーブの肉厚の均一化が図れる。(6) Functions and Effects of the Present Invention As described above, in the present invention, when the tube and the reinforcing material are pressed together, the pressure is applied at a position that avoids the seam of the reinforcing material and the creases on both edges.
In particular, the reinforcing material side does not bite strongly into the tube, and the wall thickness of the tube can be made uniform.
よつて、本考案によるとチユーブにおいて局部
的に弱い部分、ピンホールの発生しやすい部分が
ないので、ライニングの施工管理が行ない易い。 Therefore, according to the present invention, there are no locally weak parts or parts where pinholes are likely to occur in the tube, making it easy to manage the construction of the lining.
