Definitions

  • the present disclosure relates to nozzles for the dispensing of various materials and methods for dispensing various materials using nozzles, and in particular, to nozzles for use in liquid applicators, and more particularly to nozzles for use in applicators of liquid adhesives to substrates.
  • a central slot nozzle includes a single adhesive inlet through which adhesive is received and an adhesive outlet through which the adhesive is extruded.
  • These conventional slot nozzles may include one or more air inlets and outlets for receiving and dispersing low-volume, high-velocity heated process air to fiberize the adhesive and convey the adhesive particles over a short distance to a substrate.
  • the process air flow may be manipulated to control the density of the adhesive pattern.
  • only a single adhesive and a single amount of adhesive can be applied at a single application point. Historically, to achieve the application of multiple adhesives at a single application point, multiple applicators and nozzles must be provided.
  • a nozzle for a dispensing system that is capable of applying multiple fluids (e.g., adhesives) at a single application point using a single applicator and a single nozzle.
  • Such a nozzle would desirably be capable of applying different glue add-ons or different glue types at a single application point, such as in one pattern stripe and/or area.
  • nozzles for use in a dispensing system (e.g., with a material applicator) and methods of using the same.
  • the nozzles of the present disclosure may enhance hotmelt adhesive pattern uniformity and improve product features for breathability, appearance, hand, permeability, softness, and uninhibited and uniform elastic retraction.
  • Such nozzles may be used on continuous and intermittent webs for high-quality nonwovens and textiles products.
  • Such nozzles may be used in high-speed, non-contact spray applications.
  • Such nozzles may provide adhesive savings with lower add-on rates than conventional contact slot methods.
  • Such nozzles may produce non-contact fibrous coatings on irregular surfaces.
  • Such nozzles may reduce web distortion and/or heat distortion of thermally-fragile webs or those susceptible to bleed-through because adhesive cools prior to web contact.
  • Such nozzles may manage pattern precision to meet specific product attributes by manipulating pattern air flow to alter coating density.
  • Such nozzles may dispense uniform patterns and bonds with sharp and square side, leading and trailing edges.
  • Such nozzles may protect against damage or incidental contact due to recessed nozzle tips.
  • Such nozzles may allow for exacting pattern configurations for full- and partial- width coverage.
  • Such nozzles may allow for dispensing in multiple orientations.
  • Such nozzles may improve nozzle tip temperatures, such as by having greater area in contact with a heated dispensing module.
  • Such nozzles support a wide range of substrates, including heat-sensitive substrates.
  • Such nozzles may allow coating density adjustments through manipulation of pattern air flow.
  • Such nozzles may advantageously be quickly and efficiently adapted for use with a variety of different applicators or modules (e.g., for continuous and less demanding intermittent operations, for high-sped intermittent lines, for metering applications, with high speed electrically-actuated modules). Designing the nozzles as removable and interchangeable may eliminate the need for application-specific equipment, and common parts may reduce inventory and maintenance costs, streamline service, and speed product changeovers.

Abstract

La présente invention concerne une buse destinée à un système de distribution et comprenant une pluralité d'entrées de fluide, une sortie de fluide, une entrée d'air et une sortie d'air. Une première entrée de fluide reçoit un premier adhésif et est en communication fluidique avec un premier canal de fluide et une seconde entrée de fluide reçoit un second adhésif et est en communication fluidique avec un second canal de fluide. La sortie de fluide est en communication fluidique avec le premier canal de fluide le long d'un premier côté de la sortie de fluide et en communication fluidique avec le second canal de fluide le long d'un second côté de la sortie de fluide. L'entrée d'air reçoit un flux d'air et est en communication fluidique avec un canal d'air. La sortie d'air est positionnée à proximité de la sortie de fluide et est conçue pour diriger le flux d'air vers les premier et second adhésifs lorsqu'ils sont distribués à partir de la sortie de fluide.
