发明名称 Method for making a formed laminate of collapsed foam
摘要 A formed laminate (20) is made by a method and apparatus (38) by relative movement of first and second contoured mold surfaces (44,46) toward each other to compress a flexible sheet (28) and a quick reacting foamable liquid mixture (50) that has substantially completed expansion but not yet substantially cured so as to form the flexible sheet and provide a collapsed foam layer (30) bonded to the sheet.
