发明名称 Method for making formed laminate
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 vertically spaced film (56) with a foamable liquid mixture (50) there between 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. The flexible sheet (28) is preferably porous cloth, vinyl or leather. A film (56) which is preferably a nonadherent plastic such as polyethylene is preferably positioned in a vertically spaced relationship with the flexible sheet (28) either above or below the flexible sheet with the foamable liquid mixture received therebetween for the expansion prior to the compression that provides the formed laminate. The formed laminate (20) has particular utility as an article of apparel (22) and is preferably made by a quick reacting type foamable liquid mixture (50) which expands in about 8 to 25 seconds and most preferably in about 10 to 15 seconds.
