  • Patent number: 4158343
    Abstract: A machine for the coating of a strip material substrate, flat stock or the like has a plurality of spray coating guns applying coating material to the substrate. A sloping ceiling and nozzle support assembly causes any coating material deposited thereon to flow along these surfaces to the side of the substrate rather than collecting above the substrate and dripping on the substrate and degrading the desired finish. In a rotary coater, the sloping ceiling and nozzle support assembly can be combined into one rotating structure wherein centrifugal force arising from the rotation of the structure causes any coating material deposited on it to travel to its outer rotating edge where it is thrown clear of the substrate. Troughs over the entrance and exit openings of the coater collect coating material which would otherwise drip onto the substrate from above the openings and carry such coating material clear of the substrate.

  • Patent number: 4026440
    Abstract: A thermoplastic material dispensing apparatus adapted to translate feedstock from a solid state to a molten state by a novel heater block structure, and to discharge the molten feedstock through a novel discharge valve in response to operation of a novel trigger device. A novel annular cooling chamber is established about the dispenser's barrel to maintain a solid/melt interface inside the barrel adjacent to the heater block structure, that zone being air cooled by inlet air taken from a single inlet air line. The inlet air from the single line also drives the dispenser's ram through use of a novel pneumatic motor/spool valve mechanism. The spool valve is manually stroked forward to extend the dispenser's ram for extruding the feedstock, and is manually stroked rearward to retract the ram for recharging.

  • Patent number: 3960296
    Abstract: An adhesive dispensing gun for translating solid slugs of thermoplastic feedstock from the solid state to a molten state. The gun is pneumatically cooled to control solid/melt feedstock interface within the gun's barrel and is pneumatically powered to discharge the molten feedstock in response to operation of a trigger. The gun barrel includes a forming die adapter or sleeve located partially upstream of the solid/melt feedstock interface. The upstream end of the adapter or sleeve is flared inwardly so as to form a section internally of the barrel for reforming or reshaping varying sized slugs as they enter the forming die adapter and while the entering section of the slug is still in a solid state. The forming die adapter thus enables the adhesive gun to accept varying sizes of slugs while preventing meltback along the exterior of slugs which are nominally substantially smaller in diameter than the inside diameter of the barrel.
