ABSTRACT:
The apparatus and case are used with a core formed of sheets and end sheets covered on their exteriors with pressure sensitive material initially protected by release paper all bound togehter by narrow plastic binding strips along the spine edges of the core. The novel case for such a core has a spine having a strip of material covered by pressure sensitive adhesive of a width substantially greater than the thickness of the core plus twice the width of the binding strips, the same strip preferably being glued or otherwise permanently affixed to the spine of the case and extending outward to the inner edges of Davey board cover stiffeners (if used). The apparatus has right and left horizontal platens movable in and out relative to the center. The case is placed on the platens and centered. The core is held in a pivotable clamp behind the platens and is pivoted down so that the spine edge of the core is firmly attached to the spine strip of the case and continued pivoting depresses the spine of the case to the extent that the core binding strips are below the platens. The platens are then brought inward, attaching the spine strip to the end sheets. The book is rolled between rollers which engage above the plastic binding strips and below the Davey boards, thus completing firm attachment of the case to the core.
