A computerized design system for configuring an adhesive dispensing configuration. The system enables a user to graphically or otherwise manipulate markers representative of dispensing components. Programmatic rules associated with the markers guide the design process by ensuring and/or prompting compatible and otherwise appropriate marker selections for inclusion in the design.

A system for supplying melted thermoplastic material to a dispenser a hopper, a heating grid, and a reservoir block providing a reservoir. A support harness is attached to the bottom of the reservoir block. A manifold assembly is supported in the harness below the reservoir block for receiving material from the reservoir. The manifold assembly includes a pump for pumping the material to the dispenser. The manifold assembly is capable of moving vertically within the harness between an upper position in engagement with the reservoir block and a lower position, and the manifold assembly is capable of horizontal movement with respect to the support harness when it is in the lower position, so that the manifold assembly slides horizontally in and out of the support harness. A lifting mechanism connected to the support harness moves the manifold assembly vertically within the harness. The manifold assembly comprises a manifold block and a heater plate which has cast-in heater elements and which is removably attached to the manifold block.

A fluid applicator having a multi-zone noncontacting die set for dispensing a selected plurality of thin flat fiberized adhesive streams as uniform rectangular strips of adhesive on a substrate. The die set uses shims to establish the fiberizing air slot, and the adhesive dispensing and fiberizing air shims have tapered tabs to provide improved coating edge control. The fiberizing air die also has simplified fiberizing air flow, and the die set includes a mechanism for clamping the die set together which is especially suited for a multi-zone die set. The fluid applicator includes a manifold heater with a simplified and improved air flow, and a universal adhesive manifold.

A nozzle for a hot melt adhesive spray head which mounts directly to a nozzle mounting surface. To permit a series of spray nozzles to be mounted closely together, the nozzle has a threaded stud integral with and extending from the rear side of the nozzle. The adhesive passage in the nozzle mounting surface has a threaded bore for receiving the threaded stud of the nozzle. The nozzle includes a first O-ring seal to prevent the pressurized pattern air from leaking between the nozzle and the nozzle mounting surface. A second O-ring seal isolates the hot melt adhesive from the pressurized patten air at the interface between the nozzle and the nozzle mounting surface.
