Abstract
Abstract An uncased book is provided with end leaves preferably having pressure sensitive adhesive initially protected with release paper which is fabricated in various alternate ways to facilitate stripping off the release paper. The case for the book has a strip of pressure sensitive coated material at the spine area. Apparatus used to case the book has a table on which the case is positioned inside up and means for centering the case relative to the table. The uncased book is placed in a clamp pivoted to the table, the clamp being adjustable for thickness of the book. The method consists in pivoting the clamp to bring the spine edge of the uncased book into contact with the pressure sensitive spine area of the case and then to strip away the release paper for the end leaves so that the latter adheres to the insides of the top and bottom covers of the case.
