  • Patent number: 8354144
    Abstract: A method for forming a thermofusible sheet material includes providing a backing ply including a textile material and applying a mixture of a binder and a thermoplastic polymer to selected areal regions of the backing ply so as to form a two-layer bonding compound structure. The method further includes thermally treating the backing ply so as to dry the mixture and to sinter the thermoplastic polymer onto a surface of the backing ply.
