Note(s) 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. Classification according to production of particular articles in subclass Fulltext... Hierarchy... Expanded...B29D is restricted to: aspects which are characteristic for the production of a particular article, and not classifiable in subclass Fulltext... Hierarchy... Expanded...B29B or Fulltext... Hierarchy... Expanded...B29C; combined operations for making the particular article which are not fully classifiable in subclass Fulltext... Hierarchy... Expanded...B29C. [4] The codes of subclass Fulltext... Hierarchy... Expanded...B29K are only for use as indexing codes associated with subclasses Fulltext... Hierarchy... Expanded...B29B, Fulltext... Hierarchy... Expanded...B29C, or Fulltext... Hierarchy... Expanded...B29D so as to provide information concerning moulding materials or materials for reinforcements, fillers or preformed parts, e.g. inserts. [4] The codes of subclass Fulltext... Hierarchy... Expanded...B29L are only for use as indexing codes associated with subclass Fulltext... Hierarchy... Expanded...B29C, so as to provide information concerning the articles produced by the techniques classified in subclass Fulltext... Hierarchy... Expanded...B29C. [4]

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]

|  | B29B |
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]

Note(s) Attention is drawn to Note (3) following the title of class Fulltext... Hierarchy... Expanded...B29. [4] When classifying in this subclass, classification is also made in subclass Fulltext... Hierarchy... Expanded...B32B insofar as any layered product is concerned. [4] In this subclass: repairing of articles made from plastics or substances in a plastic state, e.g. of articles shaped or produced by using techniques covered by this subclass or subclass Fulltext... Hierarchy... Expanded...B29D, is classified in group Fulltext... Hierarchy... Expanded...B29C 73/00; component parts, details, accessories or auxiliary operations which are applicable to more than one moulding technique are classified in groups Fulltext... Hierarchy... Expanded...Fulltext... Hierarchy... Expanded...B29C 31/00-B29C 37/00; component parts, details, accessories or auxiliary operations which are only applicable or only of use for one specific shaping technique are classified only in the relevant subgroups of groups Fulltext... Hierarchy... Expanded...Fulltext... Hierarchy... Expanded...B29C 39/00-B29C 71/00. (See paragraph 69 of the Guide.) [4,5] In this subclass, it is desirable to add the indexing codes of subclasses Fulltext... Hierarchy... Expanded...B29K and Fulltext... Hierarchy... Expanded...B29L. The indexing codes should be unlinked. [4]

Note(s) Attention is drawn to Note (3) following the title of class Fulltext... Hierarchy... Expanded...B29. [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]

Note(s) This subclass constitutes an indexing scheme associated with subclasses Fulltext... Hierarchy... Expanded...B29B, Fulltext... Hierarchy... Expanded...B29C or Fulltext... Hierarchy...

[4] Attention is drawn to Chapter IV of the Guide which sets forth the rules concerning the application and presentation of the different types of indexing code. 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).
