Abstract
Abstract In accordance with the present invention, there is provided a novel method of making a book cover including a pocket element wherein a continuous web of cardboard material and a continuous web of paper material are supplied to a work station where they are adhered to each other along their lateral edges. The composite web which is formed is then longitudinally slit at three spaced-apart locations to separate the composite web into first and second composite sections and to form pocket elements on each of the composite sections. These composite sections are then cut in a transverse direction at spaced intervals to form first and second book covers, wherein each of the book covers include its own pocket element adhered thereto.
