  • Patent number: 12036766
    Abstract: A multilayer foam panel member including: (a) at least one top sheet substrate; (b) at least one bottom sheet substrate; and (c) a middle substrate of foam material disposed inbetween, and integral with, the top and bottom sheet substrates; wherein the foam material is produced by dispensing a reactive foam-forming fluid mixture onto a moving or stationary bottom sheet substrate of a foam manufacturing line; and wherein the foam manufacturing line includes a flexible film fluid dispensing device for dispensing the reactive foam-forming fluid mixture onto the moving or stationary bottom sheet substrate to form a multilayer foam panel member; wherein the middle substrate of foam material of the panel member has improved thermal and mechanical properties; and a process for manufacturing the above multilayer foam panel member.

  • Publication number: 20220250289
    Abstract: A manufacturing line for manufacturing a multilayer foam panel member including: (a) a storage of the components for a foam-forming fluid reactive mixture; (b) a dosing system for flowing the components of the foam-forming fluid reactive mixture to a chamber for mixing the components of the foam-forming fluid reactive mixture to form foam-forming fluid reactive mixture; (c) a flexible fluid dispensing device for receiving the foam-forming fluid reactive mixture; (d) a means for flowing the foam-forming fluid through the flexible fluid dispensing device to dispense the foam-forming fluid; (e) a moving first bottom sheet substrate for receiving the foam-forming fluid dispensed from the flexible dispensing device; (f) a means for allowing the foam-forming fluid to react, as the fluid travels on the moving bottom sheet substrate, wherein a foam material forms inbetween the moving first bottom sheet substrate and a second top sheet substrate to form a panel structure; (g) a panel structure comprising the foam mate
