Abstract: A process for continuously coating two sides of a heat fusible foam sheet with a resinous polymeric material, having the steps of: (1) melting the resinous polymeric material; (2) extruding the resinous polymeric material through a flat film die; (3) continuously passing the heat fusible foam sheet past the flat film die; (4) contacting the heat fusible foam sheet and the resinous polymeric material; (5) compressing the contacted heat fusible foam sheet and resinous polymeric material; (6) limiting the amount of reverse wrap of the heat fusible foam sheet and; (7) controlling the linear tension on the heat fusible foam sheet.
