Wafer die construction

摘要

An apparatus for manufacturing wafers is disclosed that includes a pair of rolls each containing cavities that form the wafers. The cavities each have outer edge walls that extend from the bottom portion of the cavity at an obtuse angle and the two rolls are arranged so that the cavities become effectively mirror images of each other as they engage at the nip. The cavities also have portions rising from the bottom thereof that impress a design substantially equal from both sides to proclude warping of the bread.
