- the metal steel wire 3 and the thermoplastic resin 10 are extruded to produce a composite material, if the tensile strength of the metal steel wire 3 is large, the metal steel wire 3 is pulled, and the central strand 8 and the strand 9 are pulled. As a result, the gap becomes smaller or disappears, and the molten thermoplastic resin 10 is not sufficiently filled around the central strand 8 and the strand 9. If the thermoplastic resin 10 is not sufficiently filled around the central strand 8 and the strand 9, the pulling strength of the metal steel wire 3 with respect to the thermoplastic resin 10 is lowered, and the composite material is not stabilized.
- the metal steel wire supply device 22 manages the tensile tension for the metal steel wire 3 so that a sufficient gap is formed between the central strand 8 and the strand 9.

With this apparatus, the metal steel wire 3 can be inserted into the die 5 at a temperature equal to or higher than the temperature of the thermoplastic resin 10 extruded from the extruder 6 (at the same or higher temperature). By maintaining the metal steel wire 3 at a temperature equal to or higher than the temperature of the thermoplastic resin 10, the thermoplastic resin 10 is also metal steel even when the thermoplastic resin 10 contacts the metal steel wire 3 in the die 5.
- thermoplastic resin 10 has a uniform viscosity equal to that when the metal steel wire 3 is extruded from the extruder 6 in the die 5 by maintaining the temperature of the metal steel wire 3 at a temperature equal to or higher than that of the thermoplastic resin 10. Fluidity can be maintained.

When the gap between the central strand 8 and the strand 9 is reduced or the gap is eliminated, the molten thermoplastic resin 10 is not sufficiently filled around the central strand 8 and the strand 9. If the thermoplastic resin 10 is not sufficiently filled around the central strand 8 and the strand 9, the pulling strength of the metal steel wire 3 with respect to the thermoplastic resin 10 is lowered, and the composite material is not stabilized.
- thermoplastic resin 10 when the injection pressure of the thermoplastic resin 10 is small, a void lacking the thermoplastic resin 10 is generated between the central strand 8 and the strand 9 of the metal steel wire 3, and the molten thermoplastic resin 10 is the central strand. 8 and the strand 9 are not sufficiently filled around. Similar to the case where the injection pressure of the thermoplastic resin 10 is large, the pulling strength of the metal steel wire 3 with respect to the thermoplastic resin 10 is lowered, and the composite material is not stabilized.
- the extrusion molding machine 6 manages the injection pressure of the thermoplastic resin 10.
- the extruder 6 controls the injection pressure of the thermoplastic resin 10 so that the distance between the central strand 8 and the strand 9 is maintained within an allowable range, and the thermoplastic resin 10 is interposed between the central strand 8 and the strand 9.
- the gap between the metal steel wires 3 is sufficiently filled with almost no change in the arrangement shape of the central strand 8 and the strands 9 of the metal steel wire 3 by forming so that the void lacking in is not formed. It becomes possible to do.
- thermoplastic resin pellet insertion port 7 and the inside of the extruder 6 are set to a temperature at which the thermoplastic resin 10 melts. If the thermoplastic resin 10 does not reach the melting temperature, the thermoplastic resin 10 does not melt, and the metal steel wire 3 is not filled with the thermoplastic resin 10.
- thermoplastic resin 10 in the extrusion molding machine 6 of the present invention, temperature control is performed by setting a temperature not lower than the melting temperature of the thermoplastic resin 10 and not higher than the decomposition temperature of the thermoplastic resin 10.
- the melting temperature of the thermoplastic resin 10 becomes higher than the boiling point of water, so that the water contained in the thermoplastic resin 10 can be evaporated.
- the extrusion molding machine 6 set to be equal to or higher than the melting temperature of the thermoplastic resin 10 the moisture contained in the thermoplastic resin 10 evaporates, and it is possible to manufacture the escalator handrail 30 having a low water content.
- the escalator handrail 30 can alleviate deterioration due to moisture contained in the escalator handrail 30 by managing the moisture content in the extruder 6 at a low level.

- the temperature of 10 can be kept the same, and the thermoplastic resin 10 can be filled without generating a void of the thermoplastic resin 10 between the central strand 8 and the strand 9 of the metal steel wire 3.
- the composite material generated from the die 5 does not generate a void in which the thermoplastic resin 10 is lost between the central strand 8 and the strand 9 of the metal steel wire 3, so the metal steel wire 3, the thermoplastic resin 10, and the canvas 11 is suitable for the escalator handrail 30 composed of 11.
- the escalator handrail using the composite material generated from the die 5 does not generate a void in which the thermoplastic resin 10 is lost between the central strand 8 and the strand 9 of the metal steel wire 3.
- the drawing strength of the steel wire 3 is improved and the drawing strength is stabilized.
- the temperature management of the die 5 will be described in detail. If the temperature of the die 5 is not set to the melting temperature of the thermoplastic resin 10, the temperature of the thermoplastic resin 10 discharged from the extrusion molding machine 6 is lowered, the thermoplastic resin 10 is solidified, and the preheating device The heated metal steel wire 3 coming out of 4 is also cooled, and the viscosity and fluidity of the thermoplastic resin 10 are lowered. When the viscosity and fluidity of the thermoplastic resin 10 are lowered, a void lacking the thermoplastic resin 10 is generated between the central strand 8 and the strand 9 of the metal steel wire 3, and the thermoplastic resin 10 is formed in the metal steel wire 3. Is not fully filled.
- the die 5 is controlled to a temperature at which the thermoplastic resin 10 melts.
