Abstract
A belt/die, pre-tensioned loaded windings, or other high-pressure apparatus has a series of annular rings for confining material being subjected to high-pressure treatment. The series of annular rings has an inner annular ring having an inner upper edge, an outer upper edge, an inner lower edge, and an outer lower edge. The inner lower edge is chamfered at an angle of greater than about 60° from the vertical in order to create a transition slope that mitigates tensile stresses.
