B27B SAWS FOR WOOD OR SIMILAR MATERIAL; COMPONENTS OR ACCESSORIES THEREFOR (saws specially adapted for pruning or debranching A01G3/08; sawing apparatus specially adapted for felling trees A01G23/091; features not restricted to a particular type of wood saw B23D, e.g. attaching saw blades B23D51/00; machine tool frames, beds, pillars or like members, in general B23Q1/01)
Introduced: September 1968
Description
B27B covers mechanical saws designed specifically for cutting wood and materials of similar workability, including their structural components and operational accessories. This classification encompasses various saw types such as band saws, circular saws, reciprocating saws, and frame saws, along with associated blade designs, guides, feed mechanisms, and safety devices. The scope extends to both stationary industrial sawing equipment and portable handheld saw devices used in woodworking and timber processing. Adjacent classes address general sawing machines for other materials (B23D), non-mechanical cutting tools, and downstream wood processing operations.
