404SHAPING MEANS AND SUBSEQUENT PRODUCT TREATMENT MEANS


DEFINITION

Classification: 425/404

(under the class definition) Apparatus comprising means for forming a product and subsequent means for altering the physical or chemical nature of the product.

(1) Note. When molding fluent material the product need not be removed from the mold prior to the treatment providing there is evidence that the product is self-sustaining prior to being subject to the treatment.

(2) Note. When reshaping or vulcanizing utilizing a conforming preform support, the treatment must be performed after the preform has been removed from the shaping surface.

(3) Note. The term treatment for the purpose of this subclass includes all procedures in which any chemical or physical property of a product is controlled or modified by other than mechanical shaping, i.e., causing a shaping force to be applied to the product. Included under this definition of treatment are, for example, heating, cooling, washing, drying, etc..; however, heating of a product to release it from a mold is not considered to be treatment, and will be found in subclasses 436+.
