Abstract In one form of the invention, a case for a book has a spine strip of cover material coated with pressure-sensitive adhesive in the spine area and initially separate covers on either side of the spine area. A pad of resilient material such as polyurethane foam is positioned in the center of the spine area of the case and is coated on its exposed surface with pressure-sensitive adhesive initially protected by release paper, which is removed prior to attachment of an uncased book thereto. The spine strip overlaps the spine edges of the covers and is secured thereto by the pressure-sensitive material. The uncased book is preferably provided with end leaves having pressure-sensitive adhesive initially protected with release paper fabricated in a manner to facilitate stripping off the release paper. Apparatus used to case the book has a table on which the case is positioned and clamps pivoted to the table, and movable relative to each other depending on the thickness of the uncased book. In a preferred form of the invention, edge guides for the covers move inward and outward in relation to movement of the clamps toward and away from each other to center the covers relative to the uncased book. The method consists in pivoting the clamp to bring the spine edge of the uncased book into contact with the pressuresensitive spine pad of the case and then to strip away the release paper from the end leaves so that the latter adhere to the insides of the top and bottom covers of the case.
Apparatus for assembling an uncased book to a case of the type having a flexible spine section having an exposed pressuresensitive inside surface comprising a table dimensioned to support said case laid out substantially flat with said pressuresensitive inside surface uppermost, clamp means diMensioned to support an uncased book with its spine edge exposed and connecting means connecting said clamp means to said table whereby said clamp means may be moved toward said table and the spine edge of a book held in said clamp means and said inside surface forced into engagement with each other, said clamp means comprising a pair of plates located transverse to said table, means for moving said plates toward and away from each other to accommodate books of varying thickness, and guide means interconnecting said plates to maintain said plates substantially parallel, said guide means further comprising support means for said uncased book locating said uncased book relative to said case.
