B 29 C

 SHAPING OR JOINING OF PLASTICS; SHAPING OF SUBSTANCES IN A PLASTIC STATE, IN GENERAL; AFTER- TREATMENT OF THE SHAPED PRODUCTS, e.g. REPAIRING (working in the manner of metal B 23; grinding, polishing B 24; cutting B 26 D, B 26 F; making preforms B 29 B 11/00) [4]
 

Notes

(1)

 Attention is drawn to Note (3) following the title of class B 29. [4]

(2)

 When classifying in this subclass, classification is also made in subclass B 32 B insofar as any layered product is concerned. [4]

(3)

 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 B 29 D, is classified in group B 29 C 73/00;
 

-

 component parts, details, accessories or auxiliary operations which are applicable to more than one moulding technique are classified in groups B 29 C 31/00 to B 29 C 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 B 29 C 39/00 to B 29 C 71/00.
 

(See paragraph 69 of the Guide.) [4,5]

(4)

 In this subclass, it is desirable to add the indexing codes of subclasses B 29 K and B 29 L. The indexing codes should be unlinked. [4]
