にて公知である。<Prior art> Conventionally, it has been difficult to create a composite pipe by directly wrapping other synthetic resin or rubber strips or rod-shaped materials around a flexible and easily deformable pipe. For pipes containing different materials or pipes with multiple layers, each material is wound around an iron core in order to make a composite pipe, and the iron core is then pulled out to make the product. In this case, a method of winding each material while rotating the iron core is adopted, and a method of using a drive belt suspended around the iron core as the rotation means is disclosed in, for example, Japanese Patent Publications Nos. 43-6159 and 43-6160. It is publicly known.

Since rotating the supply side of the strip relative to the core tube requires a large and complicated device, a means for rotating the core tube side is advantageous. However, it is impossible to rotate the core tube by passing a belt across it as described above if the core tube is soft and easily deformed, so it is impossible to rotate the core tube by wrapping a belt-like material uniformly around the core tube. I can't.

That is, the rotating section consists of upper and lower rotating body units R and S in which a plurality of rotational transfer belts 9 and 9' are suspended between two pair of pulleys 8, 8' and 8'', 8, and the belts are 9 and 9' are arranged at opposite angles to the core tube A held between the rotating bodies R and S, and at least one of them is rotationally driven.
grips the core tube A with its belts 9, 9',
The rotation of this belt gives rotation to the core tube A and at the same time generates a transfer force. By adjusting the angle of the belts 9, 9' with respect to the core tube, it is possible to change the transport speed of the core tube,
As a result, the winding pitch of the band-shaped body etc. can be changed.

In addition to those made of rubber alone, those having a fiber reinforcing layer, and those having a helical reinforcing core made of a hard material such as hard resin or metal wire embedded therein are applicable.
Further, the band-like or rod-like material may be made of the same or different kind of synthetic resin or rubber as the core tube, and may be further combined with hard synthetic resin, metal wire, etc. Although these band-shaped materials may be prepared as previously formed materials, it is effective to use materials that are in a melted and softened state immediately after being extruded from an extruder.

い。 Furthermore, when winding and integrating the strip material etc. around the core tube, it is effective to apply an adhesive to the surface of the core tube, but this adhesive treatment process is a separate process as a core tube treatment. Alternatively, when carrying out the present invention, it may be incorporated as a continuous process before winding the strip material or the like. Further, a heating means may be provided to soften or melt the surface of the core tube or the adhesive layer immediately before winding the strip material or the like.

and an upper rotating body S, and each rotating body R and S has a pair of pulleys 8, 8' and 8'', 8, respectively, and a plurality of rotating transfer belts 9, suspended on these pulleys.
9', supported by frames 10 and 10',
It is rotatably mounted on plates 12 and 12' on the machine base so as to be rotatable about fulcrums 11 and 11'. The angle of each belt of the rotating body units R and S with respect to the core tube A is determined by adjusting bolts 13 and 1.
3' and fixed. In the illustration of the drawing, a plate 1 supporting the upper rotating body unit S is shown.
2' is moved up and down along the column 14 by an air cylinder 15. When starting the machine, the rotor unit S is raised upwards, the core tube A is guided onto the belt 9 of the rotor R, the rotor unit S is lowered, and the core tube A is

4', universal joint 6, 6', 6'', 6
It is rotationally driven via spline shafts 7, 7' equipped with. In this example, since the belts 9 and 9' of the upper and lower rotating body units are arranged at opposite angles, when the rotation transfer belts 9 and 9' are rotated, the core tube A rotates in the direction of the arrow. move forward while doing so. The core tube A is supported by receiving rollers 17 and 18, and the strip material 2 is melted and extruded from the die 22 of the extruder while being rotated and transferred by the rotating section.

することもできる。 Since the angles α and α' of the rotational transfer belts 9 and 9' can be freely changed by the bolts 13 and 13',
It may be set as appropriate depending on the shape of the material 21 to be wound, the required pressure resistance, flexibility, etc. Rotary transfer belt 9 for the upper and lower rotating parts,
Although the deflection angles of 9' do not necessarily have to match,
Generally, it is preferable to set the angles to be the same. Further, the force with which the core tube is held between the rotational transfer belts 9, 9' can be controlled by changing the force of the air cylinder 15, or may be adjusted with the stopper 16 as the case requires. Also, a spring or screw may be used instead of the air cylinder. If an adhesive that softens when heated is applied to the core tube A in advance, for example, heating with the heating device 19 and/or 19' to soften the adhesive will make the bond between the strip material and the core tube stronger. Become. Strip material 2
It is advantageous if a cooling device 20 in which 1 is wound is provided to cool the product immediately. In addition, when rubber is used as the core tube or band-shaped material, the band-shaped material may be wound and then vulcanized. In this case, a vulcanization device may be installed to continuously manufacture pressure-resistant hoses. .
