DEFINITION

Classification: 156/84

(under subclass 60) Processes combined with the step of treating the material of which the lamina is composed to decrease the volume of the material.

(1) Note. The shrinking of the material of the lamina usually occurs by contacting the material with a liquid agent which is either (1) a constituent of the composition of the material or (2) is from an external source followed by the step of heating of the material containing the liquid.
