Abstract: A method for section reducing an encasing tube to achieve excess length of fibers within the tube. At least one, and preferably two, platforms are arranged at a selected angular offset. Each platform includes a first plurality of rollers mounted in stationary, linear and spaced apart fashion. A second plurality of rollers are mounted in an adjustable, linear spaced apart and opposing fashion relative the associated first plurality of rollers. Upon the tube passing between the stationary and adjustable rollers associated with each platform, the rollers associated with each platform simultaneously contacting first and second cross sectional locations of the tube and in order to apply lateral compressing forces to the tube which decrease its gauge length, corresponding to increasing its gauge thickness.
