Description of the invention ⑴ Background of the invention I. Technical field to which the present invention pertains The present invention relates to a manufacturing apparatus for a catheter and a manufacturing method thereof for accommodating long-distance optical fibers, wires, and cables buried in an underground network, And the like. More specifically, the present invention relates to a manufacturing apparatus and manufacturing method for a multi-channel catheter assembly, including a plurality of adjacent catheters, and is suitable for accommodating long-distance optical fibers, electric wires, and the like. II. Conventional Technical Description In the underground network industry, proper design and placement of fiber optic cables or wires is essential to maintaining the integrity of the information or power transmitted by the cables. Due to the fragile texture of optical fibers and wires, they need to be protected from sources of stress (such as temperature, pressure, contaminants). For this reason, most of the improvement methods in this industry are to design a reliable combination of coverings to cover optical fibers and wires. The following is a brief discussion of one method of setting up fiber optic cables. U.S. Patent No. 4,741,593 discloses a multi-channel catheter 'having a plurality of corrugated inner catheters, which are substantially adjacent to each other in parallel, extend in the same direction, and are in close contact with each other. Each inner catheter has a series of continuous and continuous gyrations from head to tail to form continuous bulges and depressions; and an overwrap sheath made of elastic, synthetic resin. The cover has a thickness of about 5 to 15 mils of a sheath made of polyethylene gas (sheath), and the sheath (sheath) made of polyvinyl chloride covers the entire section of the corrugated inner catheter and closes it,

A considerable length of the above-mentioned multi-channel conduit is wound on the above-mentioned reel, and it can be laid into an underground communication conduit 'or placed in a trench for direct burial. This type of multi-channel conduit can comprehensively reduce the installation cost of fiber optic cables, and many of the characteristics of the above-mentioned system can also maintain the integrity of the overall structure of the conduit ', while the use of a sheath' provides greater soil protection for the system. With regard to cable ducts for optical fibers, wires, and the like, the above are the most required characteristics. However, so far, I have not seen the above-mentioned multi-channel catheters sold in the cable catheter market. The reason is that I believe that the above-mentioned multi-channel catheters actually have several key defects in strength and flexibility, which the inventor did not notice at first. A well-known fact is that although plastic inner catheters (even non-corrugated) with smaller diameters are flexible enough to be coiled on a transportable reel, the above non-wave Finger-shaped, plastic outer catheters with relatively large diameters are not flexible enough to be coiled on a transportable reel. The above multi-channel catheters include a plurality of corrugated plastic inner catheters and non-folded plastic outer catheters. Therefore, it is understandable that the above-mentioned channel guides have sufficient flexibility to be coiled on the transportable winding coil. In my opinion, this defect is because the above-mentioned multi-channel catheters cannot be used in cable ducts. One of the reasons that appears in the market. U.S. Patent No. 5,027,864 discloses an optical fiber commonly used today w 44 0 7 2 2 V. Description of the invention ¢ 3) The installation of the cable should be made of polyvinyl chloride layer to the ground, some smaller, conduits ") pipeline can be described Separate smaller lines and install external conduit. The above-mentioned inner pipe is set with a clamp and pulled until it is finished, and it is convenient to use a fiber-optic cable to pull it in. Each has an enclosed inside to facilitate security. The above is related to the protection of construction personnel; but at the same time, the first reason is that the length of the above mentioned feet ′ " ---------

The above reference includes the use of a hollow outer conduit made of primary olefin (PVC) forty feet long to form a first-quality barrier. The above outer conduit is used as a conduit, a long-distance (mainly made of polyethylene) pipeline (or "inside through" to provide a second layer of resistance to underground matter. There are longitudinally extending ribs on the outside (Rib), 'the above is individually provided with one' or a plurality of optical fiber cables. The method of electrical delay first needs to bow the above-mentioned inner catheter into the above-mentioned method is to use a cable shaft (spoo) located on the ground to pull in The above outer pipe is in an operating area located underground, at one end of the inner pipe, and then the inner pipe is dragged until it enters the outer pipe. The inner pipe is installed to complete the tow rope (pass it through the way of filling gas) The inner tube) is a light inner tube. The result constitutes an assembly that includes several inner tubes, or a plurality of fiber optic cables, and a protective outer tube conduit. A rib is provided around the inner tube; and It is convenient to remove the above-mentioned inner guide for installation and covering fiber optic cables during maintenance and repair. It does provide some convenience for maintenance, and it also provides effective protection for fiber optic cables. The above method also has several obvious shortcomings. The material used to make the outer catheter (PVC) does not provide sufficient bullets. 'The catheter can be used with a fiber spool (sp001) (over forty).

Description of the invention (4) points, its labor cost adds a considerable expense to the total budget of the project. Second, each connection part of the outer conduit adds structural weakness to the continuous pipeline. Bit i vulnerable to infiltration by pollutants from groundwater sources. " Furthermore, the labor required to install the inner guide into the outer catheter also adds a huge amount to the cost of installation. US Patent No. 5,692,545 discloses another multi-channel catheter. The above reference includes a body portion for protecting the body, one end of the body portion extending to the second end; and at least two channels are provided, and the shaft body portion; And the area, which can accommodate at least one body portion, is made of plastic and the above-mentioned multi-channel catheter. The catheter can be produced by extrusion and installed. Therefore, the above-mentioned types of catheters also have a small number of required connections between sections, and the integrity of the data. The cable duct of the letter cable has a first end and a second end on a long and thin side; it includes a longitudinal axis, and the body portion (the body p0rti〇n is substantially parallel and completely runs through the above-mentioned channels, each of which has sufficient The communication section is thin and thin; the above body is made of a compound of rubber scraps. The inner channel part is more long with a spool to secure it. Several advantages: the above-mentioned catheters can provide less protection and increase It is said, however, that if the above percentages of defects in the rubber and rubber chips are described, the reference case can improve the flexibility of the material and increase the compound of the rubber chips of the plastics in the description of the plastic book than the above-mentioned catheters. The material duct needs to be relatively anti-ground if it needs to have a structure. According to the hardness of the above board, it is easier
