The strip is supported on a heated platen which softens the adhesive. The spine of the set of copy sheets is pressed into the adhesive on the strip. The depth of penetration of the spine into the adhesive is controlled so as to form a layer of adhesive between the spine and the strip having a predetermined thickness.
