A biscuit joiner, or biscuit jointer, is a woodworking tool used to join two pieces of wood together. It uses a small circular saw blade to cut a crescent-shaped hole, or slot, into the opposite edges of the two pieces of wood or wood-composite panels being joined. An oval-shaped, highly dried and compressed wooden biscuit is then coated with glue, or glue is applied directly in the slot, and the biscuit is immediately placed into the slot before the two boards are clamped together; the wet glue expands the compressed biscuit, further improving the bond.
Facts
Introduced When (Circa)Invented in 1956 in Liestal, Switzerland, by Hermann Steiner, whose Lamello joining system used a biscuit-shaped wooden spline to align and strengthen glued joints. 1 OriginSteiner had opened his carpenter's shop in 1944 and, in the mid-1950s, was looking for a simple way to join the recently introduced material chipboard when he invented the joining system; the first stationary biscuit joining machine followed in 1956 and the first portable biscuit joiner in 1968. 1 Introduced era (class) In the Other Atlases

History section, shop-opening and portable-joiner sentences
Steiner opened his carpenter's shop in 1944, and, in the middle of the 1950s, while looking for a simple means of joining the recently introduced chipboard, invented the Lamello joining system. In the succeeding years there followed further developments such as the circular saw and the first stationary biscuit (plate) joining machine in 1956 followed by the first portable biscuit joiner for Lamello grooves in 1968.
