Abstract
A male bookbinding member comprises a relatively thin, narrow strip having studs projecting therefrom at intervals. The ends of the studs are formed as male paper punches. A female paper punch comprises a female bookbinding strip having holes at the same intervals as the studs. Individual or small batches of paper (or other sheet material) are brought into position overlying the female punch. The male member advances toward the sheets punching them in cooperation with the female strip. The paper remains on the studs. The operation is repeated until all the sheets of the book are on the studs. The strips are forced together, excess stud lengths cut off and heads formed on the ends of the studs to rivet the book together or the strips are held together by other means. Alternatively, a hardened female punch die is used and the female binding strip brought into contact with the studs after the sheets are assembled thereon.
