An applicator gun for dispensing hot melt adhesive comprises a hydraulic material supply hose connection, an electrical power cable connection, and a hanger bracket connection. The hose connection may be inverted, and the power cable and hanger bracket connections interchanged so as to provide the applicator gun with different orientation capabilities. The applicator gun may also alternatively accommodate four-finger and two-finger trigger members, and the gun may be connected to the hose connection so as to be movable in alternative modes comprising rotation around a single linear axis or universal movement within six degrees of freedom. The gun also comprises a trigger lock mechanism comprising detent members which provide the operator with tactile indications of the trigger lock mechanism being disposed at LOCKED and UNLOCKED positions, and an enclosed weep hole or window is provided within a side portion of the gun housing so as to alert the operator to hydraulic material leakage prior to the leaking hydraulic material fouling component parts of the gun.

Strand coating methods and systems having an applicator head pivotally mounted adjacent a substrate, a coating material dispenser mounted on the applicator head, a strand guide mounted on the applicator head, wherein the strand guide and the coating material dispenser are adjustably positionable in unison relative to the substrate by pivoting the applicator head to vary the spacing of the strands relative to the substrate.

A new and improved hot melt adhesive applicator nozzle assembly comprises an adapter, a dispensing nozzle mounted within the adapter, a nozzle retainer threadedly engaged with the adapter for securing the dispensing nozzle within the adapter, an air inlet ring rotatably mounted upon the nozzle retainer and having an inlet air fitting fixedly mounted therein, and an end cap which is threadedly mounted upon the nozzle retainer. The end cap has swirl air passages integrally incorporated therein, and the end cap and air inlet ring are both fabricated from a suitable thermoplastic polymer material such that all exposed surfaces of the hot melt adhesive applicator nozzle assembly are plastic and are therefore at substantially lower temperature levels than the metal brass components of the hot melt adhesive applicator nozzle assembly. The external peripheral surface of the end cap is knurled so as to facilitate the manual removal of the end cap without the need for special tools, and most importantly, the dispensing tip portion of the dispensing nozzle is axially recessed with respect to the front surface of the end cap so as not to comprise a readily externally accessible surface portion. In this manner, the potential for burn and safety hazards to operator personnel has effectively been eliminated.

A redundant control circuit comprises a pair of heater circuits for heating a hot melt adhesive hose assembly to a predetermined temperature level, and a pair of temperature sensors which are used to sense the temperature of the hot melt adhesive hose assembly and to control energization of the heater circuits in order to maintain the desired temperature level. A first one of the heater circuits would initially be electrically connected to the hot melt adhesive hose assembly electrical circuitry, and in a similar manner, a first one of the temperature sensors would likewise be electrically connected to the hot melt adhesive hose assembly electrical circuitry. Subsequently, should a failure occur within the first one of the heater circuits, then an electrical switch mechanism would be activated so as to effectively remove the first, failed heater circuit from the hot melt adhesive hose assembly electrical circuitry, and substantially simultaneously, electrically connect the second one of the heater circuits to the hot melt adhesive hose assembly electrical circuitry. Similar switching procedures would also be implemented in connection with the pair of temperature sensors should a failure occur within a first one of the temperature sensors initially incorporated within the hot melt adhesive hose assembly electrical circuitry.

A hot melt adhesive hose assembly has a redundant control circuit fixedly mounted thereon which comprises a pair of heater circuits for heating a hot melt adhesive hose assembly to a predetermined temperature level, and a pair of temperature sensors which are used to sense the temperature of the hot melt adhesive hose assembly wherein the sensed temperature level will be used to control energization of the heater circuits in order to maintain the desired temperature level. 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 likewise 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 a first one of the temperature sensors, electrical switch mechanisms are activated 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 the second one of the temperature sensors to the hot melt adhesive hose assembly electrical circuitry. The hot melt adhesive hose assembly, with its redundant control circuit comprising the pair of heater circuits and the pair of temperature sensors, thus comprises a self-contained, stand-alone, independent operative component that can be utilized in conjunction with any hot melt adhesive supply unit (ASU).

A spool valve and valve seat assembly disposed in the control module of a hot melt adhesive dispensing system is uniquely structured so as to effectively prevent fluid communication or “cross-talk” between a first dispensing outlet port and a second recirculation port, during those periods when the control module is effectively reciprocally cycling the spool valve between its oppositely disposed extreme conditions for alternatively permitting the hot melt adhesive material to be dispensed from the first outlet port or for re-routing the hot melt adhesive material through the recirculation passage so as to prevent the hot melt adhesive from being improperly dispensed as a result of being undesirably routed to the recirculation passage.
