Appl. No.:

09/429843

Inventors:

Andrew W. Craine - Altharetta GA
Scott Richard Miller - Roswell GA
Tommy A. Pelletier - Alpharetta GA
Paul Andrew Schmidt - Sugar Hill GA

Assignee:

Nordson Corporation - Westlake OH

International Classification:

B05B 100

US Classification:

239270, 239294, 239298

Abstract:

A system for dispensing liquid material onto a moving substrate includes a liquid dispenser fluidly connected to a source of liquid material and a source of pressurized air. The liquid dispenser includes a pair of outer liquid material outlets and a plurality of inner liquid material outlets therebetween spaced along a common axis at one end of the dispenser for dispensing a plurality of strands of liquid material toward the substrate. The liquid dispenser further includes a pair of air outlets associated with each of the inner liquid material outlets and a single air outlet associated with each of the outer liquid material outlets for emitting pressurized air that is operable to oscillate the dispensed strands in directions predominantly parallel with the common axis of the liquid material outlets during flight toward the substrate to form an overlapping pattern of liquid material on the moving substrate. Methods for dispensing liquid material onto a moving substrate are also disclosed.

US Classification:

Abstract:

An electrically operated fluid dispenser for dispensing a pattern of viscous fluid onto a substrate during a run mode. The dispenser is turned off and does not dispense the viscous fluid during a standby mode of operation. The dispenser includes a dispenser body having an outlet and an armature disposed in the dispenser body for movement between an opened position allowing a fluid flow from the outlet and a closed position preventing the fluid flow from the outlet. A coil is mounted adjacent the armature and selectively generates an electromagnetic field for moving the armature between the opened and closed positions. A controller includes different apparatus and methods for using the coil as a heater as well as providing other heat transfer devices on the dispensing valve to maintain a constant temperature either, during only the run mode or, during both, the run and the standby modes. The above dispensing valve heating control facilitates a design of an electrically operated fluid dispenser having a body with a fluid passage intersecting first and second sides of the body and a dispensing outlet in fluid communication with the fluid passage. The dispenser includes a heater and has feed member mounted to the first side of the body with one end of the fluid passage in the feed plate fluidly connecting with one end of the fluid passage in the dispenser body.

International Classification:

B05B 128

US Classification:

239296, 239298, 239390, 239556, 239549, 239600

Abstract:

A system for dispensing liquid material with different configurations of air assisted fiberization or filament movement (e. g. , meltblowing, controlled fiberization). In particular, front access for mounting a selected nozzle only requires adjustment of one lever and one fastener. Features of the lever and nozzle allow assisted ejection of the nozzle, even when the nozzle has become adhered to a die body through use. In addition, a nozzle mounting surface of the die body provides a universal interface to the various types of nozzles. An air cavity in the die body and air troughs in selected types of nozzles balance and adjust air flow.
