Claim 9

A method for making book cover board structures, said method comprising the steps of (1) generating two pairs of superposed upper and lower streams of leaf board material and feeding these pairs of streams continuously in spaced and essentially parallel coplanar relation; (2) applying adhesive material onto the facing surfaces of the streams of each pair of streams of leaf board material; (3) generating a stream of hinge material and feeding this stream continuously in essentially parallel relation to the streams of leaf board material and with its lateral edge regions extending at least part way in between the upper and lower streams of each pair of streams of leaf board material; (4) pressing the facing and adhesively coated surfaces of the streams of leaf board material together with each other and with the lateral edge regions of the stream of hinge material to generate a continuous, bonded stream of the leaf board streams and the hinge material stream; (5) generating a pair of superposed upper and lower streams of spine board material and feeding this pair of streams continuously between the pairs of streams of leaf board material in essentiAlly parallel relation thereto with the upper stream of spine board material running above the stream of hinge material and the lower stream of spine board material running below the stream of hinge material; (6) applying adhesive material onto the surfaces of the streams of hinge material; (7) pressing the facing and adhesively coated surfaces of the streams of spine board material together with the upper and lower surfaces of the stream of hinge material between the streams of leaf board material to generate a continuous stream of bonded book cover board structure material, and (8) severing this stream into successive individual book cover board structures.

Claim 10

A method for making and coating book cover board structures, said method comprising the steps of (1) making a succession of book cover board structures each comprising a first leaf board portion, a second leaf board portion, and a spine board portion disposed between said first and second leaf board portions and in hinged relation thereto; (2) picking up and conveying said book cover board structures in open condition and in linear array; (3) applying coating material in fluid form to one side of the book cover board structures successively as they are conveyed; (4) turning over these structures to expose their other sides and reconveying them in open condition and in linear array, and (5) applying coating material in fluid form to said other sides of the book cover board structures successively as they are reconveyed.
