Abstract

PURPOSE:To prevent a case where the production capacity is too high or too low from the point of view of facility, by preparing a cylindrical braided item having a diameter larger than the outer diameter of an inner pie and possessing a large braid angle, inserting a hose, that is, in inner pipe into the braided item, and stretching the braided item longitudinally of the hose. CONSTITUTION:A braided item 2 has a diameter larger than the outer diameter of an inner pipe 1, comprises metal wires or organic fibers, and has a large braid angle and a short braid pitch. As the braided item 2 has a large braid angle and a short braid pitch, further the braided item 2 is pulled, the shorter the diameter becomes, the smaller the braid angle becomes, and the larger the braid pitch becomes. When the diameter becomes equal to the outer diameter of the inner pipe, it comes in firm contact with the outer circumference of the inner pipe, and the same result can be obtained as the case obtained using a braider. Therefore the diameter of the braided item becomes equal to the outer diameter of the inner pipe, and the adhered braided item can have an ideal braid angle. Accordingly, since there is no need to use a braiding apparatus such as a braider, such a case would not occur where the production capacity is too high or lower from the point of view of capacity.

It is something to do.

以下本発明を実施例により図面を参照して具体的に説明
する。Hereinafter, the present invention will be specifically described by way of examples with reference to the drawings.

る。FIGS. 1(A) and 1(B) are explanatory diagrams for explaining the hose manufacturing method of the present invention, and FIG. 1(A) shows a state in which the inner tube 1 is inserted into the cylindrical braided material 2. It shows. The braided material 2 is a cylindrical knitted material having a diameter larger than the outer diameter of the inner tube 2, and is made of metal wire or organic fiber. This braided material 2 is produced in advance using a circular knitting machine, and is a so-called dense cylindrical material having a large braid angle and a short braid pitch.

延伸中で口径が次第に小さくなりつつある編組物である
。Figure 1 (B) shows the situation in which this braided material 2 is being stretched. 3 is a braided material that is in close contact with the outer periphery of the inner tube after stretching, and 4 is a braided material whose diameter is gradually becoming smaller during stretching. It is.

同じ状態が得られるのである。Braided material 2 has a large braid angle and a small braid pinch, so
By stretching this, the diameter becomes gradually smaller, the braid angle becomes smaller, and the braid pitch becomes larger. When the caliber becomes equal to the outer diameter of the inner tube, it will come into close contact with the outer periphery of the inner tube, creating the same condition as when braided using a braider with the inner tube as the core.

従って、編組物の口径が内管の外径と等しくなり密着し
たときの編組物の編組角が理想角になることが好ましい
。Therefore, it is preferable that the braid angle of the braid becomes an ideal angle when the diameter of the braid is equal to the outer diameter of the inner tube and the inner tube is in close contact with the inner tube.

角、編組ピッチ、口径を設定しておくことが好ましい。In the present invention, when producing a braided product, it is preferable to set the braid angle, braid pitch, and diameter in advance so that the braid angle when closely attached to the inner tube is 50 to 60°.

(expressed as %). The state of the braid is curve a
It is expressed as For example, when a braid with a braid angle of nearly 90° is stretched 4), when the stretching ratio is approximately 550% (approximately 6.5 times), the braid angle becomes the ideal 54°, and the outer diameter shrinkage rate at this time is is approximately 21% (79% of the original diameter).

想編組角５０〜６０°が得られる。In such a state, it is ideal that the inner tube can be brought into close contact with the outer diameter of the inner tube. That is, in the present invention, the diameter of the braid before stretching is preferably 1.1 to 1.3 times the outer diameter of the inner tube, and the braid angle is preferably 80 degrees or more. By doing so, an ideal braid angle of 50 to 60° can be obtained with approximately 6 times the stretching.
