Abstract
A method of producing a reinforced sheet by feeding a layer of foam material to a stitching machine at a rate greater than that at which the stitched material is produced by the machine. The stitching in the product is thus disposed below the surface of the foam and hence is not destroyed during subsequent flame-bonding.
