  • Patent number: 4226544
    Abstract: A wire printing head is disclosed in which solenoids are arranged in arcuate configuration, the printing wires being connected in line with their respective solenoids. A wire guide is positioned adjacent the printing line and preformed tubes are used to guide the wires from the solenoids to the wire guide. The tubes are located at the end nearest the guide in a tube support member. An intermediate support member is provided to support the tubes, grooves being cut in the intermediate support member for this purpose. The grooves are sufficiently large to enable the tubes to take up their natural positions within their respective grooves, being secured within the grooves by an adhesive material such as synthetic resin. The solenoids are held by clamps in recesses in the head and the recesses radiate from a common point which also serves as the point from which the arc is struck.
