ABSTRACT:
An endless metal carrier is bent and treated by a heat treatment process to provide residual stress. The product carrier is cut at a portion, and the radius of the cut carrier in the free state is compared with a standard radius of a standard carrier having a predetermined residual stress to determine whether the radius coincides with the standard radius.
