Nordson Introduces AltaBlue Touch Series Adhesive Melters For Ease Of Operation And Production Efficiency; Nordson Allegro Elastic Attachment Nozzles Support Higher Speed Production And Close Elastic Centerlines

DULUTH, Ga. — June 26, 2012 — AltaBlue™ touch series adhesive melters from Nordson® Corporation provide control and flexibility for precise, demanding hot melt adhesive applications. These high-precision, variable-speed melters use an intuitive, touch screen operator interface and simplified maintenance to maximize production uptime and product quality. AltaBlue touch melters deliver the performance requirements for nonwovens production as well as for product assembly applications such as woodworking and filter.

The Optix™ user interface improves operator experience and minimizes training for set-up and operation. System status is displayed on-screen with a remote-visual-system light tower option available as well. Control features include recipe development and storage, graphing and data logging. Routine maintenance is simplified with single-tool, easy-access panels and doors, disposable basket-style filters, and accessible tank isolation valves.

AltaBlue touch melters offer production flexibility with advanced delivery control modes including:

  • key-to-line control
  • pressure build and control
  • manual
  • flow control

Variable-speed AC motors and up to four dual stream or single-stream pumps help manufacturers meet specific delivery requirements.

­­­The AltaBlue touch series also enables pressure and flow monitoring and control through optional control boards. This integrated solution can measure and control material delivery and dispense rates in response to production rate changes. Material consumption is reduced while production efficiency and product quality are improved with this variation management.

Nordson also reports its Allegro™ elastic attachment nozzles from uniformly apply hot melt adhesive to elastic strands using a novel air-assisted contact coating technology for precise adhesive deposition. Concentrated delivery of hot melt adhesive to individual elastic strands enhances bond integrity for improved creep resistance. Applications for single or multi-strand attachment include elasticized legs, leg cuffs and waistbands on disposable nonwovens infant diapers, training pants and adult incontinence products.

Patent-pending Allegro nozzles accommodate high-speed production, speeds up to 650 meters per minute, while supporting elastic centers as close as two millimeters. Integral strand guides stabilize strand position and post adhesive-application process air forms adhesive around each individual elastic strand. Exceptionally-low coating variability is achieved and add-on rates as low as 0.025 grams per coated meter optimize adhesive efficiency and maximize product performance.

The robust design and all-steel construction deliver exceptional durability and resistance to the wear associated with high-speed elastic handling, as well as simplify cleaning and maintenance. And, Allegro nozzles offer a wide operating window, across a variety of process conditions as well as a broad range of elastic and adhesive materials.

Allegro elastic attachment nozzles are compatible with Nordson Universal™ modules. In addition to standard nozzle configurations, special nozzle strand configurations and nozzle lengths up to 175 mm for many-strand applications may be ordered.
