Universal™ Control Coat® Nozzles

Universal Control Coat nozzles enhance hot melt adhesive pattern uniformity and improve product features for breathability, permeability and softness. They are used on continuous and intermittent webs for high-quality nonwovens and textile products.

Overview

Nozzles are compatible with several Nordson Universal modules, including the UM25 module for continuous and less demanding intermittent operations, Speed-Coat® module for high-speed intermittent lines, high-speed electrically-actuated E400U module, and UM3 modules for metering applications.

Features and Benefits

Produce non-contact fibrous coatings on irregular surfaces.
Reduce web distortion on thermally-fragile webs, or those susceptible to bleed-through because adhesive cools prior to web contact.
Manage pattern precision to meet specific product attributes by manipulating pattern air flow to alter coating density.
Dispense uniform patterns and bonds with sharp and square side, leading and trailing edges.
Protect against damage or incidental contact due to recessed nozzle tips.
Select nozzles in 25-millimeter increments for full coverage or 5-millimeter increments for partial coverage. Partial-coverage nozzles are available in side-justified or centered designs.
