When explaining the present invention based on the accompanying drawings as follows.

First, Fig. 1 is a partially cut-away perspective view of the assembled upper body apparatus of the present invention, Fig. 2 is a sectional view of the main parts of the extrusion die in the die lip shown in Fig. 1, and Fig. 3 is a sectional view of the main part of the embodiment of Fig. 2 as an extruder (3). Of the die lip 2 " in a helix tube forming apparatus in which a die roller 2 " and a spiral tube forming machine 1 of the die 2 As shown in FIG. 4, the auxiliary reinforcing hole 34 and the reinforcing tube hole 28 connected to the spiral pipe extrusion hole 25 having the cooling pipe and the extruded tube hole are integrally detained and extruded in the extruder 3. Similarly, the auxiliary hollow hole 33 and the tube for the reinforcement ribs 28 'connected to one side of the spiral tube extrusion tube 26 are formed using the forming roller 10 and the pressing roller 12 in the fusion process. Auxiliary reinforcement on both sides of the auxiliary hollow sphere 33 on both side walls of the reinforcement protrusion 32 formed by the spiral winding circuit by the spiral winding (34) It is a manufacturing apparatus that is extended to the left and right sides at the same time as it is formed, and is fused with reinforcement ribs 28 '', and is extruded from a separate die used in the conventional manufacturing apparatus, The configuration of the reinforcement ribs 28 ″ formed integrally with the die lip 2 ″ is provided to provide a device for manufacturing a reinforcing spiral tube that is simple and durable.

In addition, as an embodiment of the present invention, as shown in Fig. 2, as shown in Fig. 2, as shown in Fig. 3, the extruded die 25 has a long rib tool 29 formed therein. The auxiliary reinforcement 34 which is configured in the same manner as 2, but connected to the extrusion hole 24, is connected to the extrusion hole 25 for the spiral pipe of the die lip 2 " To extrude and extrude the extruded tube 27 having the ribs 29 'formed as shown in FIG. 7 (b) to reinforce the inclined support 29 " It is a device for manufacturing a product that is integrally fused to the upper side of the product, and the product is strengthened and durable than the conventional spiral tube that is extruded and fused by a conventional reinforcing rod from a separate auxiliary die.
