ABSTRACT:
An improved method of making hard and semi-rigid book covers, and the product obtained, provides a multi-layer plastic book with any desired ratio of flexibility to stiffness in the different parts of the cover such as the front and back panels, the hinge lines and the backbone panel that connects the front and back panels. A first layer of plastic is cast or extruded on a casting paper or belt or other supporting surface, and additional plastic material is applied to the first layer over areas that will form the front and back panels, and to the backbone area if the desired cover is one that is to have a stiffened backbone panel. A second layer is applied under conditions that insure a highly effective bonding and freedom from distortion when a curing step is necessary. The operation is continuous and the laminate formed is severed into separate covers as it is delivered from the laminating operation.
