摘要： Methods and apparatus for forming products having at least one first section 102 having a first wall configuration and at least one second section 104 having a second wall configuration, the second wall configuration different from the first wall configuration. A variation in wall configuration along the axis of the tubular product 100 may be designed to be axially asymmetrical at any segment of the axis 101.
