AI Technical Summary

Technical Problem

Existing laminated panel production processes face challenges in achieving uniform distribution of foam formulation across the panel width, maintaining consistent foam quality at varying flow rates and rheologies, and minimizing fouling within the distribution system, leading to product defects.

Method used

A distribution system with diverging nozzles that dispense reactive foam formulation in diverging jets, ensuring uniform layer formation by adjusting flow paths and nozzle angles to maintain consistent foam properties across a wide range of conditions.

Benefits of technology

The system achieves highly uniform laminated panel production across varying flow rates and foam rheologies, reducing fouling and ensuring consistent panel quality by maintaining uniform foam distribution and curing.

Abstract

An apparatus for dispensing a reactive foam formulation for the production of laminate panels includes a mixing head and a distribution system that defines multiple flow paths for the reactive foam toward nozzle-equipped outlets. The nozzles have multiple outlets spaced and arranged at angles to each other to distribute the foam formulation evenly over a moving underlayer.
