SECTION I - CLASS DEFINITION

This is the generic class for:

1. Apparatus including a molding surface which either shapes a fluent or bulk material, which material has plasticity as a property, into a self-sustaining article or preform of desired shape or which reshapes or resizes a plastic or "green" preform or product, not provided for elsewhere.

2. Apparatus for shaping of molten materials including metal, but excluding glass, where no molding surface is employed, e.g., by melt comminution or spheroidizing.

3. Apparatus for treating (e.g., vulcanizing, etc.), a product made by the apparatus of this class, not provided for elsewhere.

4. Apparatus for randomly depositing and bonding (uniting) particulate material, not provided for elsewhere.

5. A combination of apparatus of this class with any diverse working or treating apparatus which combination is not provided for elsewhere.

(1) Note. Caveat relating to administration of this class. Only the assignment of "original" copies of patents issued after 1934 are to be used as evidence of appropriate classification within the class.
(2) Note. Class 425 does not provide for a product made by the apparatus of the class. A specific article is classified with the respective art class to which it belongs, (e.g., a rubber glove is provided for elsewhere).
