ABSTRACT:
A formed laminate (20) is made by a method and apparatus (38) by compressing 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. 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).
