Title: Thermoelectric matrix printing head

Abstract: A matrix printing head for use in a thermoelectric printing process has a plurality of electrical conductors which are fixed in predetermined relationship to one another. The conductors are disposed in a plurality of plates, and the plates are fixed in predetermined relationship to each other to form a matrix of electrical conductors. The plates may be made of an electrically conductive material and have insulating slots cut completely through the plates to form the conductors. The plates are then stacked, sandwich fashion, with a layer of insulating material between each plate. The plates and layers may be pinned to insure accurate alignment, and an adhesive is applied to the surfaces of the plates and insulating layers. The stack is then compressed and the ends of the conductors are exposed to provide a printing surface at one end and leads for the electrical connection of means to activate selected conductors at the other end.
