Abstract
A new and improved hot melt adhesive hose assembly has a hot melt adhesive hose core, a pair of heater circuits wrapped around the external peripheral surface of the hose core, and a pair of temperature sensors also disposed in contact with the external peripheral surface of the hose core. A first one of the heater circuits is initially electrically connected to the hot melt adhesive hose assembly electrical circuitry, and in a similar manner, a first one of the temperature sensors is electrically connected to the hot melt adhesive hose assembly electrical circuitry. Should a failure occur within the first one of the heater circuits, or within the first one of the temperature sensors, electrical switch mechanisms, which are fixedly mounted upon the hose assembly, can be actuated so as to effectively remove the first, failed heater circuit, or the first, failed temperature sensor from the hot melt adhesive hose assembly electrical circuitry, and substantially simultaneously therewith, electrically connect the second one of the heater circuits, or temperature sensors, to the hot melt adhesive hose assembly electrical circuitry. The hot melt adhesive hose assembly, including the heater circuits, the temperature sensors, and the switch mechanisms, effectively comprises a self-contained, stand-alone, or independent operative component that can be utilized in conjunction with any adhesive supply unit (ASU) and its temperature controller.
