Abstract

An elongated pipe is held in a first constant tension mechanism and then, while the tension is maintained, the pipe load is shifted to a second constant tension mechanism by automatically correlating the declining tension force of the first constant tension mechanism with the increasing tension force of the second constant tension mechanism until the pipe is completely shifted to the second constant tension mechanism.
