The plate joiner, also referred to as a biscuit joiner, is a woodworking tool used to join two pieces of plywood, particle board or fiberboard together. It was originally designed in Switzerland, the birthplace of many tool ideas. In 1956, Hermann Steiner was looking for an easier way to join two pieces of chipboard and accidentally stumbled upon the plate joiner principle. The tool's rotary blade cuts a hole in opposite edges of two pieces of wood, and then a glue-covered biscuit (also called a beech or domino) is placed in the slot. The two pieces of wood are then pressed together and the glue eventually expands, making the joint secure. Not long after Steiner's Lamello Joining System was introduced, other tool makers followed suit with their own versions of the plate joiner. Today, we offer the latest versions of this great tool that manufacturers have been improving ever since its creation.
