Abstract: A thermal print head and a method of manufacturing it using a thermally stable support mandrel and a plurality of spaced turns of copper-coated resistance wire wrapped on the mandrel. The turns are held on the mandrel by slabs of potting compound retained in under-cut grooves on the mandrel while the connections to the print elements are made by slitting the turns along a longitudinal groove in the mandrel. The copper coating is removed to expose the resistance wire at the desired printing element locations.

Abstract: A thermal transfer printing device includes a thermal printing head of the corner-edge type having heating elements disposed on one edge and forming a printing bar. The edge faces a backing roller, is parallel to the axis thereof, and around which an ink ribbon is led directly away from a letter or envelope to be printed. A shell which is provided on the underside of the thermal printing head faces the backing roller. The shell extends immediately up to the printing bar and has a bottom surface with a region adjacent the printing bar at approximately the same height as the printing bar. The thermal printing head including the shell and the backing roller, are adjustable relative to one another. Good ink particle detachment and a relatively low contact force are provided. Disadvantages with regard to soft and sensitive mail can be avoided and the service life of the thermal printing head is prolonged due to a lower contact force. A good print quality is achieved, irrespective of the finish of the letters or envelopes and at a high transport speed of the latter.
