[Prior art]

 Conventionally, there are passenger conveyors such as escalators or electric walkways that move passengers by placing them on steps. The passenger conveyor is provided with handrails or hand belts for endlessly moving and gripping the passengers without losing their balance, along with the step of placing and moving the passengers.

As shown in FIG. 2, a hand belt 1 for a passenger conveyor is a belt having a substantially C-shaped cross section in which a rubber material 5 is coated on a core body 4 which is a laminated body of canvas 2 with tension members 3 interposed therebetween. It is in the form of a circular shape, and is used by being attached to a mechanism that drives endless rotation. As shown in FIG. 4, the method of manufacturing the passenger conveyor handbelt 1 having such a structure uses a rubber material 5 on a core body 4 having a substantially C-shaped cross section by an extrusion device (not shown). While being extruded and covered, the rubber material 5 and the core body 4 are pressed against each other by the press molding device 23, and a constant winding force is applied to the winding drum 21 by a drive motor or the like (not shown), and the winding is performed. At this time, in order to perform press molding with a constant tension applied to the tip portion of the passenger conveyor hand belt 1, the clamp 10 is connected to the take-up wire 22 fixed to the take-up drum 21, and the clamp 10 is attached. The hand belt 1 for the passenger conveyor is fixed to the front end portion thereof, and the hand belt 1 for the passenger conveyor and the winding drum 21 are connected to each other.

As a result, a constant tension is applied to the passenger conveyor hand belt 1, and the tension member 3 is stretched to prevent troubles such as meandering of the tension member 3. On the other hand, in order to improve the production efficiency of the passenger conveyor hand belt 1, two passenger conveyor hand belts 1A and 1B may be simultaneously pressure-bonded in the press molding apparatus 13 as shown in FIG. In this case, a take-up drum 11 for taking up two passenger conveyor hand belts 1A, 1B at the same time is used, and the take-up drum 11 and the respective passenger conveyor hand belts 1A, 1B are The pulling jigs 10A and 10B and the take-up wires 12A and 12B are connected to each other.

[0005]

[Problems to be solved by the device]

 However, the tension between the clamp 10A used for the passenger conveyor hand belt 1A and the clamp 10B used for the passenger conveyor hand belt 1B is not always uniform due to the fluctuation of the clamps, etc. When it is wound at the same time, the tension may not be applied to the passenger conveyor hand belt 1B, for example.

As a result, as shown in FIG. 6, troubles such as meandering, overlapping and eccentricity of the tension member 3 occurred, and unevenness was generated on the surface of the passenger conveyor hand belt 1. Further, when the passenger conveyor hand belt 1 in which the tension member 3 meanders, overlaps and is eccentric, is used for a long period of time, the tension member 3 is worn and the tension member 3 is cut and the passenger conveyor hand belt 1 is cut. There was a risk that the tension member 3 would fly out from the surface of the and there was a safety issue.
