    Abstract: A method and apparatus for bonding at least two films of resinous material such as polyester films to one another wherein at least a portion of one surface of one polyester film is placed contiguous with at least a portion of one surface of the other polyester films adjacent thereto. At least one layer of resinous material such as a layer of polyester is placed adjacent each of the other surfaces of the polyester films to be bonded and opposite the contiguous portions of the surfaces. The contiguous portions of the polyester films to be bonded are compressed against one another by pressure applied to the two outermost layers of polyester.
