B27H BENDING WOOD OR SIMILAR MATERIAL; COOPERAGE; MAKING WHEELS FROM WOOD OR SIMILAR MATERIAL
Description
B27H covers mechanical and thermal processes for bending wood and similar fibrous materials, encompassing techniques such as steaming, soaking, and pressing to achieve curved components for furniture, vehicle parts, and structural applications. This subclass includes cooperage operations—the manufacture and assembly of wooden barrels, casks, and similar staved containers—as well as the production of wooden wheels and related components. The classification encompasses both the machinery used for these operations and the resulting manufactured items, but excludes general wood shaping or sawing operations covered elsewhere in B27.
