EXPANSION JOINTS

Description

PRODUCT DESCRIPTION

Expansion joints can be made out of a variety of different materials. Some types of rubber expansion joints are made with a molding process. Typical joints that are molded are medium-sized expansion joints with bead rings, which are produced in large quantities. These rubber expansion joints are manufactured on a cylindrical mandrel, which is wrapped with bias cut fabric ply. At the end the bead rings are positioned and the end sections are folded inwards over the bead rings. This part is finally placed in a mold and molded into shape and vulcanized. This is a highly automated solution for large quantities of the same type of joint.
