ABSTRACT:
An adhesive bound pad of paper such as loose leaf binder paper is provided which is secured in assembly by adhesive material, lining or partially lining holes along selected edges of the paper stack forming the pad. The edges of the paper pad remain free of adhesive material and thus are not distorted upon separation of the sheets from the pad. The adhesive bound pad is manufactured by assembling a selected number of sheets of paper into a stack and drilling or otherwise forming holes, such as binder holes, along one of the edges of the stack. Thereafter, the coating of adhesive material is applied within the holes of the stack so as to entirely coat the paper at the holes or to coat selected portions of the paper at the holes as desired. After the adhesive material has been allowed to cure or has been cured the paper is releasably retained in adhesive bound pad form and the manufacturing process is complete. Individual sheets of paper may be pulled away from the pad. The adhesive material may also provide reinforcement for the paper at the hole, especially in the case of loose leaf binder paper.
