Lines with other classes and within this class
Class 100 is the generic class for apparatus for pressing particulate material. Class 264 is the generic class for corresponding methods; for the line between these classes see paragraphs under Lines With Other Classes and Within This Class of the class definition of Class 264.
COMBINED PRESSING ELSEWHERE CLASSIFIED
This class provides, in subclass 102, and in the various subclasses preceding it for pressing in combination with other features. Nearly all pressing elsewhere classified includes not only pressing, per se, but in combination with other devices or steps. Where other classes set out subclasses directed to combinations of pressing with other features, which combinations relate to those appearing in the Class 100 schedule, suitable cross search notes to the subclasses concerned have been made.
See References to Other Classes, below, referencing this section for classes that each include pressing and have a subclass directed to combined features generally, one of which may be pressing, or a specific combination of pressing with other features and not appearing in the Class 100 schedule or of special note.
BINDING AND PRESSING ELSEWHERE CLASSIFIED
Methods and apparatus are intermixed in the art as elsewhere classified and they are included together in References to Other Classes, referencing this section.
Plastic shaping. The shaping of material by molecular flow under pressure is generically in Class 264, Plastic and Nonmetallic Article Shaping or Treating: Processes, and divided among other classes according to the nature of the material worked. Of these, Class 99, Foods and Beverages: Apparatus, and Class 426, Food or Edible Material: Processes, Compositions, and Products, are generic to food material, and Class 72, Metal Deforming, as to metal. Class 419, Powder Metallurgy Processes, for making articles from particulate material including metal particles. See the definitions of these classes for the distribution of related art.
The compaction of particulate material into a definite shape wherein at least some of the particles maintain their identity in the product is classified in Class 100 and Class 264. For the line, see the definitions to Class 264, particularly subclasses 109-128.
