摘要： A process for precisely controlling the thickness of a heat-softenable sheet material (52) comprising heating the material to bring it to a softened condition, compressing the material while in the softened condition to the desired thickness or somewhat less and then cooling the material to a temperature below its softening point so that it sets while precisely maintained at the desired thickness. The material is cooled by passing it between substantially parallel cooling plate (32,34) rigidly spaced with a separation equal to the desired thickness of the material.
