Abstract

A mandrel for transporting hollow cylinders including an elongated arm having a first end and a second end, an expandable disk supported at the first end and means supported at the second end to expand the expandable disk, the mandrel arm comprising an elongated body having an imaginary axis and at least three fins extending substantially radially from the arm, each of the fins having an alignment shoulder adjacent the first end adapted to receive an end of a hollow cylinder and to coaxially align the cylinder with the elongated arm. This mandrel is used in a process for coating hollow cylinders.
