(under the class definition) Apparatus wherein shaped material is subjected to an operation which controls or modifies the chemical or physical properties of the work by other than causing a shaping force to be applied to the work.
(1) Note. Included under this definition are heating, cooling, washing, dying, etc..
(2) Note. Included in this and indented subclasses is both the treatment of fluent material which has been shaped but not yet solidified and the treatment of previously molded articles. Apparatus for treatment, per se, are generally classified in the appropriate treatment classes but are included herein when so specialized as to be excluded from the definition of the other classes.
(3) Note. Included in the indented subclass of this subclass is shaping means and concurrent treating means.
(4) Note. Vibrating or tamping means are not considered to be treating means for this group but are provided for in subclasses 456+ below.
(5) Note. Included under this definition are heating or cooling means which are necessary for the molding operation (e.g.., thermosetting, etc..), not merely for treating the material.
SEE OR SEARCH THIS CLASS, SUBCLASS: 86, for means handling or treating liquid or vehicle condensate combined with shaping means.
174, for means applying radiant energy to a shaped product.
317, for means to heat or cool the apparatus in the nature of a safety means for the apparatus.
404+, for shaping followed by a subsequent treating.
407, for apparatus comprising press forming apparatus with opposed press members and having distinct means for heating and for cooling; see the search notes thereunder.
