Hot melt applied in a spiral pattern [spiral spray]

A stable coating method that can be applied non-contact when you want to apply a thin and wide layer for product bonding! Regardless of low or high speed, it achieves minimal splatter and beautiful uniform coating!

The "Spiral Spray" is a method of applying hot melt in a spiral fiberized form onto the substrate. It achieves beautiful spiral application with minimal scattering, regardless of low or high speeds. It is also possible to apply using a foaming machine for foamed spirals. 【Features】 ■ Soft finish with a pleasant texture and breathability ■ Reduces waste/loss of hot melt adhesives ■ Solvent-free/low-solvent for environmental/recycling measures ■ High-speed intermittent adhesion is possible. The spiral can accommodate up to 72,000 rotations per minute, with a width of approximately φ15–20mm. 【Features of the nozzle with secondary air】 ■ The guide air stabilizes the pattern, and the clean air protects the nozzle, significantly reducing maintenance without foreign matter adhesion. ■ Spiral application of high-viscosity hot melts, which was difficult with conventional methods, is now possible. * For more details, please refer to the PDF document or feel free to contact us. 【Applications/Examples of Achievements】 ■ Non-woven fabrics ■ Films ■ Filters
