  • Patent number: 6527992
    Abstract: A method and apparatus for making a formed laminate (20) discloses an applicator (42) for depositing a quick reacting foamable liquid mixture (36) onto a transfer member (38) from which the reacted foam (40) and any foamable liquid mixture that has yet to react is transferred onto a flexible sheet (28). Relative movement of a pair of contoured mold surfaces (74,76) of a mold (68) toward each other compresses the flexible sheet (28) and the foam while the foam is in a transitory state (41) after substantial completion of expansion and before substantial curing has taken place such that it is still viscous. This compression provides a collapsed foam layer (30) and forms the foam as well as the flexible sheet (28) to provide the formed laminate (20). A liner (32) is also provided on the opposite side of the collapsed foam as the flexible sheet.
