| description | PROBLEM TO BE SOLVED: To provide a continuous vulcanization method with which a rubber product with a hollow part is continuously vulcanized with vulcanization speed nearly equal to extrusion speed, while retaining the shape of the product even when the unvulcanized rubber product with the hollow part to be extrusion molded is long and has a large cross-sectional shape.SOLUTION: An unvulcanized rubber product C with a hollow part c to be molded with continuous extrusion, having a liquid heat medium injected into the hollow part, is sent to, and immersed in, a liquid vulcanization tank 3 in which the liquid heat medium 5, consisting of one liquid or a plurality of liquids with specific gravity less than that of the unvulcanized rubber product, is heated and stored, and vulcanized under normal pressure. The unvulcanized rubber product is continuously vulcanized by retaining the liquid heat medium in the hollow part and maintaining an immersed state in the liquid heat medium 5 without being floated with buoyancy, and uniformly heating the product, while retaining the shape, in accordance with extrusion speed under normal pressure. |
