- peeling member 3 one selected from a heat-resistant sheet-like, tape-like or film-like member that does not adhere to the member constituting the belt body 1 and is not fused during vulcanization is used. Specifically, as the peeling member 3, a vulcanized or unvulcanized rubber sheet, a release sheet made of a fluororesin, a polyethylene sheet, or the like is used.
- the belt body 1 is pulled into the belt conveyor apparatus and set at the site where the conveyor belt is used.
- the peeling member 3 embedded in the belt body 1 is peeled off from the belt body 1.
- stacked on the peeling member 3 can be removed easily.
- the core 1a formed in the step shape covered with the peeling member 3 is exposed.
- the extra length portion 1X of the belt main body 1 is left on the front end side in the length direction of the belt main body 1 from the portion in which the core body 1a is formed in a step shape in advance. Therefore, when joining the longitudinal end 1A of the belt main body 1, the extra length portion 1X is gripped and the belt main body 1 is drawn into the belt conveyor device. Whether or not the extra length portion 1X is provided is optional, but the extra length portion 1X is provided to facilitate the drawing operation. After the belt body 1 is retracted, the excess length portion 1X is cut off.
- the other core body 1 a formed in a step shape to be a bonding partner is opposed to the exposed core body 1 a.
- Adhesive Q or the like is applied to at least one surface of the opposed cores 1a to laminate the cores 1a.
- the laminated portions are sandwiched between vulcanization molds and joined by vulcanization adhesion by heating and pressurizing at a constant temperature for a certain period of time.
- the core body 1a at the end of the belt body 1 in the longitudinal direction is formed in a step shape in advance, and the top of the core body 1a formed in the step shape is covered with the peeling member 3.
- a conveyor belt (belt main body 1) can be prepared in advance at a belt manufacturing factory or the like.
- the cover rubber 4 laminated on the peeling member 3 can be removed by peeling off the peeling member 3 when joining the longitudinal ends 1 ⁇ / b> A of the belt body 1. Thereby, the core 1a formed in the step shape covered with the peeling member 3 can be exposed.
- the portion where the core bodies 1a are laminated is vulcanized and joined. Good. Therefore, it is not necessary to perform complicated joining work at the site where the conveyor belt is used, where space and processing facilities are limited as in the prior art. That is, at the joining work site, the excision work and the buffing work at the longitudinal end 1A of the belt body 1 can be simplified, so that the joining work of the longitudinal end 1A of the conveyor belt can be performed as compared with the conventional method. Time can be greatly reduced.
- the circumference of the endless belt body 1 can be accurately grasped in advance.
- a take-up mechanism that adjusts the length by moving the driving roller 2A and the driven roller 2B in the longitudinal direction.
- the core body 1a at both ends 1A in the length direction of the belt body 1 is formed in a step shape in advance, and the core body 1a formed in this step shape.
- the belt main body 1 can be vulcanized and molded with the cover rubber 4 laminated on the release member 3.
- the core body 1 a at one end 1 ⁇ / b> A in the length direction of the belt body 1 is formed in a step shape in advance. Then, the core body 1a formed in this step shape is covered with the peeling member 3, and the belt body 1 is vulcanized and molded with the cover rubber 4 laminated on the peeling member 3.
- the other core body 1a to be joined is formed in a step shape at the site where the conveyor belt is used as usual. And it is also possible to laminate the cores 1a facing each other, and vulcanize and join the laminated parts.
- the work time can be reduced to about 2/3 including the preparation time. Therefore, it was found that the number of workers could be reduced to two.
