  Here, the second core body 6 and the second tension member 7 are integrally formed by extrusion molding or injection molding through a molding machine (not shown), and cut by a predetermined length. It is formed.

  Next, the manufacturing process of the moving handrail 1 of FIG. 1 will be described. 4-9 is explanatory drawing for demonstrating a part of manufacturing process of the moving handrail 1 of FIG. 4, 6, and 8 are perspective views showing the belt-like body first end 1b and the belt-like body second end 1c of the handrail belt-like body 1a. 5 and 7 are enlarged cross-sectional views showing a part of the first end 1b of the belt-like body. Further, FIG. 9 is a perspective view showing a state in which the band-shaped body first end 1b and the band-shaped body second end 1c and the handrail connector 5 are combined.

  First, the strip-shaped body first end 1b, which is one end in the longitudinal direction of the handrail strip 1a, is cut in a direction perpendicular to the longitudinal direction of the handrail strip 1a, and the first end is formed on the strip-shaped first end 1b. A surface 1d is formed. At the same time, the belt-like body second end 1c, which is the other longitudinal end of the handrail strip 1a, is also cut in a direction perpendicular to the longitudinal direction of the handrail strip 1a, and the second end 1c of the handrail is cut. 2 The tip surface 1e is formed. Then, as shown in FIG. 4, the first tip surface 1d and the second tip surface 1e are disposed so as to face each other.

  In the next step, as shown in FIG. 5, the band-shaped body first end 1b is cut along the width direction (line A in FIG. 5) of the handrail-shaped band 1a. By this cutting, the first core 2 at the first end 1b of the belt-like body is separated into a tension member layer 2c as a tensile body layer and a surface layer 2d. The tension member layer 2 c is a layer including a plurality of first tension members 4. The surface layer 2d is a layer on the opposite side of the canvas 3 with respect to the tension member layer 2c. The belt-like body second end 1c is processed in the same manner as the belt-like body first end 1b, and the first core body 2 of the belt-like body second end 1c is separated into the tension member layer 2c and the surface layer 2d.

  As shown in FIGS. 6 and 7, the surface layer 2d of the first end 1b of the belt-like body is shown in FIG. 6 from the first front end surface 1d to the inner side in the longitudinal direction of the handrail belt 1a (right side in FIG. 6). It is removed (removed) by dimension B (for example, about 80 mm). As a result, the upper surface of the tension member layer 2c at the first end 1b of the belt-like body is exposed. Similarly to the case of the belt-like body first end 1b, the surface layer 2d of the belt-like body second end 1c is removed (removed) by the dimension B shown in FIG. The upper surface of the tension member layer 2c at the two ends 1c is exposed. Here, the 1st front end surface 1d comprises the front end surface of the longitudinal direction of the tension member layer 2c of the strip | belt-shaped body 1st end 1b. The second tip surface 1e constitutes the tip surface in the longitudinal direction of the tension member layer 2c of the belt-like body first end 1b.

  Then, as shown in FIG. 8, the position of the removed portion of the surface layer 2d of the first strip end 1b and the position of the removed portion of the surface layer 2d of the second strip end 1c correspond to each other. The first tip surface 1d and the second tip surface 1e are abutted against each other. That is, the first tip surface 1d and the second tip surface are such that the upper surface of the tension member layer 2c at the first end 1b of the strip and the upper surface of the tension member layer 2c at the second end 1c of the strip are flush with each other. 1e face each other. As a result, a series of connection depressions 1f are formed from the removed portion of the surface layer 2d at the first end 1b of the strip and the removed portion of the surface layer 2d at the second end 1c of the strip. In addition, the shape of the connection depression portion 1f is a shape recessed from the surface opposite to the canvas 3 in the thickness direction of the handrail surface portion 2a toward the canvas 3 side.

  In this state, as shown in FIG. 9, the strip-shaped body first end 1 b and the strip-shaped body first are connected to the connection depression 1 f (where the surface layer 2 d is removed from the strip-shaped body first end 1 b and the strip-shaped body second end 1 c). The handrail connector 5 formed in advance in a separate process is fitted so as to pass the two ends 1c. And the combination part of the strip | belt-shaped body 1st end 1b, the strip | belt-shaped body 2nd end 1c, and the handrail connection body 5 is heated with the heating type | mold (not shown). By being heated in this manner, the thermoplastic elastomer forming the first core 2 of each of the first end 1b and the second end 1c of the strip and the thermoplastic elastomer forming the second core 6 are mutually connected. Heat-sealed. Thereafter, the heated portion is cooled.

  Through the steps as described above, both ends in the longitudinal direction of the belt-like handrail strip 1a are connected to each other, and the endless moving handrail 1 is formed. Here, FIG. 10 is a cross-sectional view showing a connection point between the belt-like body first end 1b and the belt-like body second end 1c of the moving handrail 1 of FIG. As shown in FIG. 10, the boundary surface (joint surface) between the belt-like body first end 1 b and the handrail connection body 5 and the boundary surface between the belt-like body second end 1 c and the handrail connection body 5 disappear all. In addition, the boundary surface (bonding surface) between the strip-shaped body first end 1b and the strip-shaped body second end 1c also disappears. Thereby, the processing trace when the design surface in the strip | belt-shaped body 1st end 1b and the strip | belt-shaped body 2nd end 1c removes the surface layer 2d disappears.

  Furthermore, in the connection location of the strip | belt-shaped body 1st end 1b and the strip | belt-shaped body 2nd end 1c, the 1st tension member 4 of the strip | belt-shaped body 1st end 1b and the 2nd tension member 7 of the handrail connection body 5 are handrail surface part 2a. They are arranged so as to overlap each other in the thickness direction and to be parallel to each other. Similarly, the first tension member 4 at the second end 1c of the belt-like body and the second tension member 7 of the handrail connector 5 are arranged so as to overlap each other in the thickness direction of the handrail surface portion 2a and to be parallel to each other. ing.

  In the method for manufacturing the moving handrail of the passenger conveyor as described above, the first tip surface 1d and the second tip surface 1e are abutted with each other, so that a series of belt-like body first end 1b and belt-like body second end 1c are formed. A connection recess 1f is formed, and the handrail connection body 5 is fitted into the connection recess 1f, and the second core body 6 of the handrail connection body 5 is formed between the band-shaped body first end 1b and the band-shaped body second end 1c. Since the first core body 2 and the first core body 2 are fused together, the core body is scraped off from the tensile body as in the manufacturing method of Patent Document 1, and the manufacturing method of Patent Document 2 is exposed. This eliminates the need to cut the tensile bodies at both ends in the longitudinal direction of the moving handrail in stages in the longitudinal direction of the moving handrail, thereby simplifying the connecting process and improving work efficiency during connecting process. Can be improved.

  The first tension member 4 at the first end 1b of the belt-like body and the second tension member 7 of the handrail connecting body 5 are arranged in parallel to each other, and the first tension member 4 at the second end 1c of the belt-like body and the handrail. Since the second tension member 7 of the connection body 5 is arranged in parallel to each other, the second tension member 7 passes the strip-shaped body first end 1b and the strip-shaped body second end 1c, so that the strip-shaped body first The tensile strength in the longitudinal direction of the handrail strip 1a at the connecting portion between the first end 1b and the strip second end 1c can be improved, and the first strip 1b of the handrail strip 1a and the strip first The two ends 1c can be firmly connected to each other.

  Here, the work of shaving off the core body from the tensile body as in the manufacturing method of Patent Document 1 to expose the tensile body, and the tensile bodies at both ends in the longitudinal direction of the moving handrail as in the manufacturing method of Patent Document 2 In the operation of shifting the cutting stepwise in the longitudinal direction of the moving handrail, it is necessary for the worker to process the tensile body manually using a cutter. On the other hand, in the manufacturing method of the moving handrail of the passenger conveyor as described above, complicated processing work like the manufacturing method of Patent Documents 1 and 2 is unnecessary, and the processing work is simplified. The step of separating the core body 2 into the tension member layer 2c and the surface layer 2d and the step of removing the surface layer 2d can be performed by NC (Numerical Control: numerical control) processing by a machine tool (not shown). it can. That is, the process of separating the core body 2 into the tension member layer 2c and the surface layer 2d and the process of removing the surface layer 2d can be automated.

  In the first embodiment, the first core body 2 of the handrail strip 1a and the second core body 6 of the handrail connector 5 constitute the design surface of the moving handrail 1. However, the present invention is not limited to this example. Instead, the surfaces of the first core body 2 and the second core body 6 may be covered with a design member such as rubber, and the design surface of the moving handrail 1 may be configured by the design member.

  Further, in the first embodiment, the removal dimension of the surface layer 2d in the core body 2 of the strip-shaped body first end 1b and the strip-shaped body second end 1c is about 80 mm, and the length dimension of the handrail connector 5 is about 160 mm. However, the present invention is not limited to this example, and as these dimensions become longer, the connection strength between the strip-shaped body first end 1b and the strip-shaped body second end 1c increases. It can be changed accordingly.

  Further, in the first embodiment, the first tension member 4 and the second tension member 7 made of steel wire are used as the first tensile body and the second tensile body, respectively. However, the present invention is not limited to this example. You may use plate-shaped members, such as a metal plate, as a 1st tensile body and a 2nd tensile body. In this case, a plate-like member as the first tensile body is provided in the first core body along the width direction and the longitudinal direction of the first core body, and the plate-like member as the second tensile body is the second. What is necessary is just to provide along the width direction and longitudinal direction of a core.

It forms so that it may incline from the width direction one end side of the handrail strip | belt-shaped body 1a to the width direction other end side with respect to the orthogonal surface orthogonal to the longitudinal direction of the strip | belt-shaped body 1a.

  Further, in the step of removing the surface layer 2d of the band-shaped body first end 1b and the band-shaped body second end 1c according to the second embodiment, as shown in FIG. 12, the removed portion of the surface layer 2d, that is, the tension member layer 2c The upper surface is processed so as to have a parallelogram shape. Thus, when the first tip surface 1d and the second tip surface 1e are brought into contact with each other, the boundary surfaces on both sides in the longitudinal direction of the connecting depression 1f of the handrail strip 1a are the first tip surface 1d and the second tip surface. It is formed to be inclined similarly to the surface 1e.

  Further, in FIG. 3, in the manufacturing process of the handrail connection body 5 of the first embodiment, the handrail connection body 5 is formed in a rectangular shape, but in the manufacturing process of the handrail connection body 5 of the second embodiment, FIG.
