A46D MANUFACTURE OF BRUSHES
Introduced: September 1968
Description
A46D encompasses manufacturing processes and apparatus for producing brushes of all types. This classification covers machinery and methods for bristle insertion, tufting, setting, and assembly of brush heads, including automated and semi-automated production systems. It includes techniques for fastening bristles or filaments into brush stocks, securing handles to brush heads, and finishing operations specific to brush manufacture. Adjacent classifications (A46B covers brush types themselves, A46C covers brush materials) are distinguished from this class which focuses on the production technology rather than the finished brush or its raw materials.
IPC and CPC are identically structured here. All 6 subcodes exist in both systems.
2 shared codes have differing titles between IPC and CPC.
