SECTION B — PERFORMING OPERATIONS

SHAPING

|  | B29 |
WORKING OF PLASTICS; WORKING OF SUBSTANCES IN A PLASTIC STATE, IN GENERAL; WORKING OF SUBSTANCES NOT OTHERWISE PROVIDED FOR (see Section C, particularly Fulltext... Hierarchy... Expanded...C08, for chemical matters; shaping clay or other ceramic compositions, slag, or mixtures containing cementitious material Fulltext... Hierarchy... Expanded...B28B)

|  | B29 |
Note(s) For the purpose of this class, "plastics" means macromolecular compounds or compositions based thereon. A product is not classified here unless it results from a process which is itself classified in this class.

|  | B29B |
PREPARATION OR PRETREATMENT OF THE MATERIAL TO BE SHAPED

|  | B29C |
SHAPING OR JOINING OF PLASTICS; SHAPING OR JOINING OF SUBSTANCES IN A PLASTIC STATE, IN GENERAL; PROCESSING USED PLASTIC MATERIAL (processes or apparatus predominantly used for thermoplastic substances Fulltext... Hierarchy... Expanded...B29F; for thermosetting substances Fulltext... Hierarchy... Expanded...B29G; for natural or synthetic rubbers Fulltext... Hierarchy... Expanded...B29H)

|  | B29D |
PROCESSES OR APPARATUS FOR PRODUCING PARTICULAR ARTICLES FROM PLASTICS OR FROM SUBSTANCES IN A PLASTIC STATE (specially adapted for working of natural or synthetic rubbers Fulltext... Hierarchy... Expanded...B29H; combined with packaging Fulltext... Hierarchy... Expanded...B65B)

|  | B29F |
PROCESSES OR APPARATUS PREDOMINANTLY USED FOR SHAPING OF THERMOPLASTIC SUBSTANCES (shaping of plastics in general, casting plastics in an open mould, joining plastics Fulltext... Hierarchy... Expanded...B29C)

|  | B29F |
Note(s) This sub-class includes the working of thermosetting substances by the same processes or apparatus.

|  | B29G |
PROCESSES OR APPARATUS PREDOMINANTLY USED FOR THE SHAPING OF THERMOSETTING SUBSTANCES (working of thermosetting substances by processes or apparatus also applicable to thermoplastic substances Fulltext... Hierarchy... Expanded...B29F)

|  | B29H |
PROCESSES OR APPARATUS SPECIALLY ADAPTED FOR WORKING OF NATURAL OR SYNTHETIC RUBBERS (working of rubber in the same manner as plastics, see the relevant sub-classes for plastics)

|  | B29J |
SHAPING OR WORKING OF MATERIALS, NOT OTHERWISE PROVIDED FOR; MOULDING BOARDS OR ARTICLES FROM WOOD PARTICLES

|  | B29J |
Note(s) This sub-class applies only if the main constituent of the material is not covered by any other sub-class.
