BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below.
It will be described with reference to the drawings. Embodiment 1. 1 is a configuration diagram showing a moving handrail for a passenger conveyor according to Embodiment 1 of the present invention. In FIG. 1, 1 is a slide cloth, 2 is an elastomer layer, 2a is a first layer of the elastomer layer 2, 2b is a second layer of the elastomer layer 2, 2c is a third layer of the elastomer layer 2, and 3 is a band-shaped tension member. 4 is a pattern (character). Here, inside the moving handrail having a C-shaped cross section, there is a slide cloth 1 made of cotton, synthetic fiber, or the like, which comes into contact with a handrail guide or a handrail driving roller (neither is shown). On the outer periphery of the slide cloth 1, there is an elastomer layer 2 formed of a thermoplastic elastomer. In the figure, the elastomer layer 2 is the first layer 2a,
It is composed of three layers, a second layer 2b and a third layer 2c, of which the third layer 2c constitutes a decorative layer for a moving handrail. The number of layers of the elastomer layer 2 is not limited to three as shown in FIG.

A band-shaped tensile member 3 is embedded in the first layer 2a in order to prevent the extension of the moving handrail and increase the tensile breaking strength. Of course, the tensile body 3 here may be a wire or the like instead of the strip shape. Further, a pattern (character) 4 is provided between the third layer 2c and the second layer 2b below it. This pattern (character) 4 needs to have elasticity and flexibility so that it can follow the bending deformation of the handrail.
It is provided by means of sticking a thin member such as a thermoplastic resin sheet or paper / metal foil onto b, printing means such as screen / stamp using quick-drying ink, and minute engraving means such as laser or hardening. . The color of the third layer 2c, which is the decorative layer, is transparent so that the pattern (character) 4 thus provided can be seen through the handrail surface.

Next, a method of manufacturing a moving handrail for a passenger conveyor according to Embodiment 1 of the present invention will be described with reference to FIG. 2 are the same as those in FIG. 1, and are designated by the same reference numerals. In order to obtain the moving handrail for the passenger conveyor according to the present embodiment, the slide cloth 1 is previously prepared.
Is cut into a predetermined width, and its upper surface is surface-treated with an adhesive or a coupling agent, or is sufficiently dried without any treatment. Also, the tensile body 3 having a predetermined size is surface-treated with an adhesive or a coupling agent, or
Alternatively, wash and dry thoroughly. After that, as shown in FIG. 2 (a), using an extrusion molding machine, together with the slide cloth 1 and the tensile body 3 described above, the first layer of the elastomer layer 2 was formed.
The thermoplastic elastomer to be the layer 2a is extruded into a C-shape from an extruding die to perform integral molding.

Then, as shown in FIG. 2 (b), the second layer 2b of the elastomer layer 2 is formed on the outside of the C-shaped molded product molded in the previous step in the extrusion die set in the extrusion molding machine.
The thermoplastic elastomer is molded integrally. After that, as shown in FIG. 2C, the pattern (character) 4 is provided on the surface of the C-shaped molded body molded in the previous step by the method described above. However, when a sheet or the like is attached, an adhesive is applied to the back surface of the sheet to adhere it, or when it is made of a thermoplastic material, it is heat-sealed and temporarily fixed. The main purpose of this adhesion is to prevent misalignment of patterns (characters) in the subsequent molding process.

Next, in the extrusion die set in the extrusion molding machine, the thermoplastic elastomer to be the third layer 2c of the elastomer layer 2 is integrally formed on the outer side of the molded body provided with the pattern (character) 4 in the previous step. Chemical molding is performed, and the final handrail shape is completed as shown in FIG. In addition, the molded body that has come out of the extrusion molding machine in each step is cooled and solidified through a cooling tank and its shape is stabilized.

By the way, when such a molding method is adopted, the third layer 2c serving as a decorative layer has a sufficient thickness and is sufficient for a material extruded from an extrusion molding machine to form the third layer 2c. It is necessary to keep a certain amount of heat. As a result, the material with heat extruded from the extrusion molding machine is deprived of heat by the molded body formed in the previous step, the fluidity is lowered, and the material does not sufficiently wrap around the entire surface of the molded body, resulting in voids. It can be prevented from occurring.

Then, a strong adhesion effect (including intermolecular force) is generated between the layers and between the layer and the pattern (character), so that the layers are bonded. Further, in the present embodiment, since all the elastomer layers are formed of the same main raw material, in addition to the adhesion effect between the respective elastomer layers, a fusion effect in which they are melted and mixed with each other also occurs, and further strengthened. It will be glued. In addition, as the main raw material of the elastomer layer 2,
Examples thereof include polyurethane-based, polystyrene-based, polyvinyl chloride-based, polyester-based, and polyolefin-based elastomers.

As described above, in this embodiment, the third layer 2c formed by extrusion molding has a sufficient thickness and is firmly adhered to the second layer 2b, so that the handrail is used for a long time. Even if continued, the third layer 2c does not crack or wear, and the pattern (character) 4 covered by this layer 4
Can be protected for a long time.

Further, in the present embodiment, the core body is entirely made of a thermoplastic elastomer (a high molecular substance which exhibits rubber elasticity at room temperature, and synthetic rubber is a typical example). Extrusion molding is possible in all the manufacturing processes, and the pattern can be bonded by the adhesion effect between the layers without being pressed and bonded for several minutes as in the conventional case, so that the manufacturing time is very short.

It is desirable that the diameter of the optical fiber cord 5 be as small as possible so that it can follow the bending deformation of the handrail. The optical fiber cord 5 is not coated on the surface so that the light can be emitted to the surroundings when transmitting the light. Since the optical fiber cord 5 has no coating, it becomes a bare optical fiber cord,
