Introducing Tsubaki products playing active roles in each tire manufacturing process.

Tire Manufacture
Forming Process

Components such as tread, carcass, and bead that make up the tire are accumulated and affixed to the drum to be formed into a tire. The tire formed in this process is soft and called a raw tire (green tire).

Tsubaki's Plastic Modular Chains and Power Cylinders are used for component feeders.

Component Feeder

Component Feeder (cut process)

Components in sheet shape are cut and automatically fed to the drum that forms the tire.

The gaps in connection areas are reduced to zero by combining with plates in a comb shape similar to that of escalators.

This prevents roll-in of the end of rubber sheets.

  • Zero roll-in

  • Chain pitch: 19.05 mm, link height: 14.3 mm
