    摘要： An apparatus for spraying heated hot melt adhesive in elongated strands or fibers in a con­trolled, spiral pattern upon a substrate comprises a spray gun (10) having a nozzle (14) formed with an adhesive delivery passageway (56) and an air delivery passageway (94) both of which terminated at the base of the nozzle (14). A nozzle attachment (18) in the form of a one-piece annular plate is mounted to the base of the nozzle (14) by a cap (62). The annular plate (18) is formed with a throughbore (110) which receives hot melt adhesive from the adhesive delivery passageway (56) and ejects an adhesive bead through a nozzle tip (108) formed on the outer side of the plate (18) opposite the nozzle (14). An annular groove (112) formed in the outer side of the plate (18) facilitates drilling of air jets bores (118) therein at an angle relative to the through­bore and adhesive bead ejected therefrom. The air jet bores (118) receive pressurized air from the air delivery passageway (94) in the nozzle (14) and direct jets of pressur­ized air substantially tangent to the adhesive bead to form elongated adhesive fibers and to impart a spiral motion to the elongated fibers so that they are formed in a compact spray pattern for deposition onto a substrate.

    摘要： Apparatus for melting and dispensing thermoplastic material including a hopper (11) for receiving solid thermoplastic material, a flow-through grid melter (12) secured to the bottom of the hopper and a reservoir (13) mounted beneath the grid melter. The grid melter includes multiple parallel ribs (39) extending across the width of the bottom of the grid melter. A single sinuous electrical resistance heater (50) is cast in situ into the ribs of the grid melter. The underside of the grid melter is provided with recesses (45) which function as accumulators to prevent the buildup of pressure on the underside of the grid melter upon remelt of solid thermoplastic material located above the level of the top of the grid melter.

    摘要： An apparatus for melting and dispensing thermoplastic material comprising a melter tank (11), a pump (12) contained within the melter tank, a dispenser (16), and a manifold block (13) mounted on the bottom of the melter tank. Thermoplastic material melted in the tank flows from the melter tank, through the pump, through the manifold block, to the dispenser. The pump is mounted in the tank and is provided with a built-in pressure control valve (115) operable to circulate the pump flow back to the tank when the dispenser flow is terminated or when there is greater pump flow than is required at the dispenser.

    摘要： A support structure for a slot coating die is provided. The support structure comprises a plurality of support members connected with a frame, and a slot coating die head structure which rests on and is coupled to certain of the support members. The frame comprises a pair of spaced apart side frame members (30,32), and the plurality of support members comprises: (i) a pair of outer support (34,36) members, each disposed adjacent a respective side frame member (30,32) and pivotally supported thereon, (ii) a pair of intermediate support members (38,40), each disposed adjacent a respective outer support member (34,36) and pivotally supported thereon, and (iii) a pair of inner support members (42,44), each disposed adjacent a respective intermediate support member (33,40) and pivotally supported thereon. Each of the pair of inner support members (42,44) has a respective support surface, and the slot coating die structure rests on the support surfaces of the pair of inner support members (42,44) and is coupled to the pair of inner support members (42,44) for movement therewith.
