ABSTRACT:
In accordance with the instant invention, biaxially-oriented polymer sheet is produced by continuously forging polymer feedstock between pairs of converging opposed surfaces. After it is biaxially-oriented, the sheet product is either cooled or heated while being restrained and advanced. The sheet produced by the process and apparatus has substantially uniform strain distribution over the width and length thereof as well as through the thickness thereof.
