Abstract
Abstract Methods and apparatus for adhering outer facing fabrics to fusible interlining backing fabrics by pressing such fabrics together by a suction or negative pressure created by a vacuum, and heating the fabrics while they are so pressed together to cause them to adhere to each other to form laminated materials.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
63 words
A method as defined in claim 1 wherein the outer facing fabric has an irregular, non-planar of non-uniform surface and the substantially non-porous cover sheet is sufficiently flexible and possesses sufficient size and suitable drape as to conform thereto, whereby the outer facing fabric and the fusible interlining backing fabric are pressed together with a substantially uniform pressure over their entire contacting surfaces.
Claim 2
Dependent Claim
20 words
A method as defined in claim 1 wherein the flexible, substantially non-porous cover sheet is a silicone rubber-coated glass fabric.
Claim 3
Dependent Claim
21 words
A method as defined in claim 1 wherein the outer facing fabric and the fusible interlining backing fabric have different thicknesses.
Claim 4
Dependent Claim
136 words
Apparatus for adhering an outer facing fabric to a fusible interlining backing fabric which comprises: a vessel having a porous surface upon which an outer facing fabric and a fusible interlining backing fabric may be placed; a flexible, substantially non-porous cover sheet of sufficient size and suitable drape as to be adapted to be placed on and conformably cover the porous surface of said vessel and the backing fabric and facing fabric thereon; means to develop a vacuum in said vessel under said porous surface to apply suction to the non-porous sheet whereby the backing sheet and facing sheet are pressed together with a substantially uniform pressure over their entire contacting surfaces; and means to apply heat to the backing fabric and facing sheet while they are so pressed together to adhere them to each other.
