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 hot melt adhesive application apparatus (10) including a thermally-sensitive electronic control assembly (34). The electronic control assembly (34) is adequately thermally insulated from heat generated by the melt tank (76). The electronic control assembly (34) as well as the pneumatic control assembly (60) are positionable so as to face either to the front or to the rear of the apparatus. The apparatus includes a sturdy base (12) by which the apparatus may be lifted without damage to the enclosure. In addition, the tank enclosure includes a flow passage for molten hot melt adhesive that has leaked past the pump shaft to flow back into the tank (76).

摘要： Apparatus comprising a melter tank (11), a pump (12) contained within the melter tank (11), a dispenser, and a manifold block (13) mounted on the bottom of the melter tank. Thermoplastic material melted in the tank (11) flows from the melter tank (11), through the pump (12), through the manifold block (13), to the dispenser. The pump (12) is mounted in the tank and is either a reciprocating piston type or a rotary gear type pump, the two being interchangeable upon the tank. If a gear type pump is used, it is provided with a built-in pressure control valve 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. Contained interiorly of the manifold block (13) in the flow path between the pump and the dispenser there is a replaceable filter ( 1 04). This filter (104) is threadedly mounted in the manifold block but the assembly is such that upon removal of the filter (104), molten thermoplastic material cannot contact and clog the filter mounting threads.

摘要： An adhesive dispensing apparatus for applying continuous, parallel adhesive beads onto the center portion of a substrate and intermittent, parallel adhesive beads on the outer portions of a substrate, particularly the plastic backing sheet of a disposable diaper. The apparatus includes a slot nozzle, divided into two center sections and two end sections, which is formed with flow passageways for each section having a coat hanger profile including a plurality of spaced, discharge orifices to form the parallel beads. A valving arrangement including solenoid-operated center dispensing valves for each center section of the nozzle, and solenoid-operated dispensing and recirculation valve pairs for each end section of the nozzle, controls the flow of adhesive to the nozzle. The center dispensing valves are continuously opened during an operating run to apply continuous adhesive beads on the center portion of the substrate, and the outer dispensing valves are opened and closed intermittently to form gaps on the substrate without adhesive where the leg holes of the diaper are cut. When the outer dispensing valves are closed, the recirculation valves are simultaneously opened to maintain constant adhesive flow to the center dispensing valves.

摘要： Apparatus comprising a melter tank (11), a pump (12) contained within the melter tank (11), a dispenser, and a manifold block (13) mounted on the bottom of the melter tank (11). Thermoplastic material melted in the tank (11) flows from the melter tank (11) through the pump (12) through the manifold block (13) to the dispenser. The melter tank (11) comprises a novel electrical resistance heating element (80) cast into the bottom wall (14) of the tank (11). The heating element (80) is asymetrically shaped within the bottom wall (14) of the melter tank (11) and is so configured that the length of the heater element (80) within any portion of the bottom wall (14) is proportional to the mass of material, including melter tank (11), manifold block (13), pump (12), and thermoplastic material to be heated by the given length of heater element (80) within that portion. Additionally, the tank (11) side walls are generally triangular in cross section with the thicker part of the triangular shaped side walls located adjacent the bottom of the tank. A portion of the heating element (80) is located directly under each side wall so that heat is effectively conducted from the bottom wall (14) into the side walls (36,38), and from the side walls (36,38) into the thermoplastic material contained within the tank (11).
