This class does not cover the working of plastics sheet material in a manner analogous to the working of paper, which is covered by class Fulltext... Hierarchy... Expanded...B31. [4]
In this class, the following term is used with the meaning indicated:
"plastics" means macromolecular compounds or compositions based on such compounds.
In this class, the following rules apply:
The working of plastics is, as far as possible, classified primarily according to the particular shaping technique used, e.g. in subclass Fulltext... Hierarchy... Expanded...B29C. [4]
A product is not classified in this class unless it results from a technique which is covered by this class.
PREPARATION OR PRETREATMENT OF THE MATERIAL TO BE SHAPED; MAKING GRANULES OR PREFORMS; RECOVERY OF PLASTICS OR OTHER CONSTITUENTS OF WASTE MATERIAL CONTAINING PLASTICS [4]

Note(s)
In this subclass, it is desirable to add the indexing codes of subclass Fulltext... Hierarchy... Expanded...B29K. The indexing codes should be unlinked. [4]
Inventions classified in this subclass are, in so far as any layered product is concerned, also classified in subclass Fulltext... Hierarchy... Expanded...B32B. [4]
In this subclass, it is desirable to add the indexing codes of subclass Fulltext... Hierarchy... Expanded...B29K. The indexing codes should be unlinked. [4]
In this subclass, the following term is used with the meaning indicated:
"rubber" covers:
natural or conjugated diene rubbers;
rubber in general (for a specific rubber, other than a natural rubber or a conjugated diene rubber, see the group provided for such macromolecular compounds). [4]
This subclass constitutes an indexing scheme associated with subclass Fulltext... Hierarchy... Expanded...B29C, relating to the articles produced. The indexing codes should be unlinked. [4]
