Abstract
A method and apparatus for continuously fabricating three-dimensional (3D) filament reinforced foam insulation slabs. Rows of X or longitudinal filaments are fed longitudinally into a machine in spaced, stacked horizontal planes. Rows of Y or transverse filaments are fed transversely into the machine in spaced, stacked horizontal planes. Z or vertical filaments are fabricated into units of four vertical spaced lengths of strands which fit into each of the vertical column squares formed by the X-Y filaments to form the continuous X-Y-Z orthogonal array. Urethane or equivalent foam is discharged onto a moving belt beneath the filamentary array which is moved in the same direction and at the same rate as the belt carrying the foam. The foam material froths or foams upwardly through the filamentary array as they move along to the next station for curing. After sufficient cure, the foamed array is cut from the frames and into desired length, forming planks.
