Introduced: September 1968
Description
B27F covers specialized woodworking machinery and techniques for creating and assembling wooden joints, particularly dovetailed joints and mortise-and-tenon connections used in furniture and construction. It includes slotting machines designed to cut grooves, slots, and mortises in wood or similar materials, as well as the general category of nailing and stapling machines for fastening wood components. This classification encompasses both the mechanical equipment used to produce these joints and the processes involved in their manufacture, distinct from more basic wood machining operations covered elsewhere in B27.
