際に把持する移動手摺が設けられている。2. Description of the Related Art Generally, a large number of passenger conveyors such as escalators and auto lines are installed in department stores and stations.
Such a passenger conveyor is provided with a moving handrail to be gripped when the passenger moves on the steps.

の内側にスライダ面104が形成されている。FIG. 11 is a view showing the structure of a general moving handrail provided on this type of passenger conveyor. This FIG.
The moving handrail 4 shown in FIG. 2 has a C-shaped cross section, and covers a plurality of laminated canvases 101, a plurality of tensile members 102 provided between these canvases 101, and the surface of the canvas 101. And a decorative rubber 103.

手摺4の両端部を連結して無端状にする必要がある。In such a handrail 4 of a passenger conveyor, the design of the decorative rubber 103 is particularly important. Since the decorative rubber 103 is driven in synchronization with the twelve steps 51, the decorative rubber 103 is forced to bend by a drive wheel (not shown), and cracks occur over time. Similarly, the canvas 101 traveling on the guide rail surface (not shown) wears over time, causing a serious accident such as jumping out of the tensile member 102 inside the canvas 101. Therefore, before the aging of the canvas 101 and the decorative rubber 103 occurs, the moving handrail 4 is periodically replaced.
When such a moving handrail 4 is exchanged, it is necessary to wind the new moving handrail 4 around a balustrade (not shown), and then connect both ends of the moving handrail 4 to form an endless shape.

In FIG. 8 (b), A, B, C, and D on the horizontal axis indicate longitudinal portions of the heating and pressurizing device, and a simple vulcanized cosmetic rubber is provided between portions A and B and between portions C and D on both sides. The portion between the intermediate portions B and C corresponds to the portion of the unfused canvas 32. Further, T1 on the vertical axis represents the remelting limit temperature of the decorative rubber, T2 represents the fusion lower limit temperature of the decorative rubber, and T3
Indicates the maximum fusion temperature.

The unfused canvas 32 shown in FIG. 8 is preformed into a C-shape to form the moving handrail 4 shape. Next, the lower mold 2 of the heating and pressing device is placed on the surface of the back unvulcanized decorative rubber 33 shown in FIG. 10 which is attached to the unfused canvas 32, and the middle mold is formed as shown in FIG. Then, the unmolded ear rubber 34 is stuck thereon, and the upper mold 1 is installed.

The fusion work is performed for a predetermined time in a temperature range up to the fusion upper limit temperature T3.

The moving handrail 4 is sandwiched between the lower mold 1 and the lower mold 2, and the electric heating element 5 is energized to heat the upper mold 1 and the lower mold 2. Also,
In order to avoid a shortage of the decorative rubber 103 at the time of fusion, the unvulcanized decorative rubber 33 and the rubber 34 are set extra. As a result, a gap is formed between the upper mold 1 and the lower mold 2. However, as the unvulcanized cosmetic rubbers 33 and 34 are melted, excess cosmetic rubber flows out of the lower mold 2 through the burr holes 2 a. Since the fluid flows to both ends of the molds 1 to 3, the upper mold 1 gradually sinks and the pressing force decreases.

Here, the horizontal axis of FIG. 9 indicates the fusion time, and t on this horizontal axis.
0 indicates the end of the fusing operation. The vertical axis in FIG. 9 indicates the amount of displacement of the upper mold 1.

As the process proceeds, at the time t0 at the end of the fusion, as shown in FIG. Therefore, it is necessary for the operator to retighten the plurality of fastening bolts 6 and nuts 7 manually during welding in order to maintain the pressing force.

It is designed to be taken out of the heating and pressing device.

Pressure devices have been proposed. This conventional heating and pressurizing device regulates the upper limit temperature of the upper surface and lower surface electric heating elements in response to the operator turning on and off the power supply of the upper surface and lower surface electric heating elements, and sets a predetermined predetermined temperature. A temperature difference control means for turning on / off the power so as to be able to heat the inside is provided.

う問題もある。By the way, in the above-mentioned conventional heating and pressurizing apparatus, as shown in FIG. 8 (a), electric heating is performed over the entire length (portions A to D) of the upper mold 1 and the lower mold 2. Since the body 5 is installed, as shown in FIG. 8 (b), the entire area A to D exceeds the remelting limit temperature T1 of the decorative rubber. That is, the sum of the unfused portion lengths of the portions B to C sandwiched between the upper mold 1 and the lower mold 2 and the simple fused portion lengths of the portions A to B and the portions C to D is the mold 1 to 3. Since the decorative rubber is melted over the entire length of the molds 1 to 3, excess cosmetic rubber flows into the burr holes 2a or flows toward the ends of the molds 1 and 2. When the excess cosmetic rubber reaches the ends of the molds 1 and 2, the ambient temperature rapidly falls below the remelting limit temperature T1, so that the flow of the cosmetic rubber stops rapidly, There is a problem that unevenness of the decorative rubber is generated in the vicinity of the simple vulcanized decorative rubber 31. In addition, since a portion where the decorative rubber and the canvas are already fused is heated and pressed, this portion needs to be fused again, and there is a problem that the number of fusion operations increases.

が可能である。In the invention according to the first aspect of the present invention, the fusion portion of the moving handrail between the canvas and the decorative rubber is sandwiched between the molds and heated at a predetermined fusion temperature, and the movable handrail is heated at a predetermined fusion temperature. Since the temperature rise of the decorative rubber is suppressed at the end portion in the longitudinal direction, the flow of the decorative rubber gradually stops when excess cosmetic rubber flows from the fused portion of the decorative rubber toward the end of the mold. Further, there is no possibility that a portion where the decorative rubber and the canvas are already fused is heated at a predetermined fusion temperature. As a result, it is possible to prevent unevenness of the decorative rubber from being generated at the longitudinal end of the mold, and it is possible to reduce the number of times and time for fusing the decorative rubber, thereby improving the efficiency of the heating and pressing operation of the moving handrail. It is possible to achieve. And if the insulator is formed of a composite material having a low thermal conductivity, for example,
It is possible to reliably reduce the temperature at the end of the insulator during the fusion work.

By heating for a time and applying a predetermined pressure, the unvulcanized decorative rubbers 33 and 34 and the unfused canvas 32 can be formed into the cross-sectional C shape of the moving handrail 4. At the same time, the molds 1 and 2 are insulated by the insulating material 21 and cooled in a cooling tank 23 filled with water at the ends of the molds 1 and 2, thereby forming the portions A and D at both ends as shown in FIG. Each temperature is lowered to around the remelting limit temperature T1, and refusion of the vulcanized portion of the moving handrail 4 which has already been vulcanized with rubber can be prevented. By this heating method, the intermediate portion B in the longitudinal direction
The temperature range between the lower limit temperature T2 for fusion of the unvulcanized decorative rubbers 33 and 34 and the upper limit temperature T3 for fusion is kept constant between C, and the temperature distribution between the portions A and B and the portions C and D at both ends. Is substantially lower than the fusion lower limit temperature T2, and slightly exceeds the remelting limit temperature T1 near the end of the electric heating element 5. Due to this heating state, the vulcanized rubber vulcanized portion of the moving handrail 4 and the unvulcanized cosmetic rubber Since the elements 33 and 34 are fused together, uniformity can be obtained. Thus, compared to the conventional case shown in FIGS. 6 to 12 described above, the ratio of the portion exceeding the remelting limit temperature T1 is low, and the connection line and the unevenness after the heating and pressing do not need to be generated. Therefore, the efficiency of the fusion work can be improved.
