Patent
CA 2134235
A formed laminate (20) is made by a method and apparatus (38) by compressing a flexible sheet (28) and a foamable li- quid 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 arti- cle 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.
On fabrique un aggloméré stratifié (20) au moyen d'un procédé et d'un dispositif (38) de compression d'une feuille souple (28) et d'un mélange liquide et moussant (50) sensiblement dilaté mais pas encore complètement durci, de façon à façonner la feuille souple et à constituer une couche de mousse repliée (30) collée à ladite feuille. La feuille souple (28) est, de préférence, un tissu poreux, du vinyle ou du cuir. Une pellicule (56), de préférence, un plastique non adhésif, tel qu'un polyéthylène, est placée en fonction d'un espacement vertical par rapport à la feuille souple (28), soit au-dessus soit au-dessous de ladite feuille, le mélange liquide et moussant se trouvant entre la feuille et la pellicule, de manière à se dilater avant sa compression permettant d'obtenir le stratifié aggloméré. Ledit stratifié aggloméré (20) s'utilise particulièrement en tant qu'article de vêtement (22) et se fabrique, de préférence, au moyen d'un mélange liquide et moussant à réaction rapide (50) se dilatant en 8 à 25 secondes environ et, de préférence, en 10 à 15 secondes environ.
