AI Technical Summary
Technical Problem
Existing methods for manufacturing rubber member assemblies face challenges in temperature control complexity, leading to instability in the manufacturing process, particularly when unvulcanized rubber materials are joined at their ends.
Method used
A method involving a contact step where a second rubber composition is brought into contact with the end face of a first vulcanized rubber member, followed by heating to form a joint, ensuring stable assembly through controlled vulcanization bonding.
Benefits of technology
This approach allows for the stable manufacturing of rubber component assemblies by simplifying temperature control and ensuring consistent joint formation.

Abstract
To stably manufacture rubber component assemblies. [Solution] The manufacturing method for the rubber member assembly 3 includes a contact step and a vulcanization bonding step. The vulcanization bonding step is performed after the contact step. In the contact step, the second rubber composition 25 is brought into contact with the end face 14 of the first rubber member 10 in the first longitudinal direction DL1. The first rubber member 10 contains a vulcanized product of the first rubber material. In the vulcanization bonding step, the second rubber composition 25 is heated. By heating the second rubber composition 25, a linear second rubber member 20 is formed and the first rubber member 10 and the second rubber member 20 are bonded to each other. The second rubber member 20 contains a vulcanized product of the second rubber material.
