Universal™ Summit™ Nozzles
Universal Summit nozzles improve bond strength and product quality in hot melt adhesive nonwovens and product assembly laminating applications.
Overview
Universal Summit nozzles deliver superior control of hot melt adhesive fiber size, density and pattern width for numerous nonwovens and product assembly laminating applications.Nozzles are compatible with all Nordson Universal modules and Universal applicators.

Features and Benefits
- Gain high bond strength at low add-on rates in continuous and intermittent operations.
- Control adhesive fiber size, density and pattern width for better bond performance.
- Produce low-density, large-fiber patterns for maximum bond strength; open patterns for absorbency; or highly dense fine-fiber patterns for heat-sensitive substrates.
- Achieve greater uniformity in the cross-web direction.
- Provide leak-free operation with serviceable, surface-mounted elastomeric seal.
