DEFINITION

Classification: 264/303

(under subclass 301) Processes in which the deposition or accretion on the mold surface is of a nonuniform or varying thickness to produce articles which have an irregular or nonuniform cross-sectional wall thickness, or in which the accretion rate or overall thickness of the accretion is controlled or regulated by a compound or nonlinear movement of the molding form or surface.
