to the cover 12 and leaves and l shaped glue strip 28 exposed along the marginal edges of the inner surface of cover 12 as a result a second leaf adheres to the l shaped glue strip 28 that remains exposed on the inner surface of cover 12 thereby forming a pocket with a third edge being attached at fold 14 and a fourth edge remaining open for receiving a card 32 in one embodiment of the invention three books are placed end to end in an upstate position during the process anywhere from approximately 12 18 books may be placed between two dies 36 of the type shown in fig5 immediately after the resin emulsion is applied die 36 includes a lower strip 40 and an upper narrow strip 42 a plurality of openings 44 exists between the upper and lower strips 40 42 between adjacent openings 44 are adjoining strips 46 the books and dies are placed in an air powered vise and thereafter squeezed together in order to set the adhesive the vise is squeezed under approximately 2800 lbs in 2 of pressure for a sufficient amount of time in which to properly seal the adhesive to the cover 12 the pressure may range between about 2000.
