ABSTRACT:
For convenient packaging of plastic bookbinding strips, cassettes are provided. The end edges of each strip are received in channels formed in opposed side rails. The rails engage adjacent either end the depending legs of transverse spacer bars. The spacer bars have plural sockets to engage projections on the upper ends of the legs so that the spacing between side rails may be varied to accommodate strips of different lengths--e.g., 81/2 inches, 11 inches, etc. Different length legs may be used to accommodate different length studs formed on the strips. By eliminating the legs entirely, flat female binding strips may be packaged in the cassette. A detent is provided in the ends of the rails preventing removal of strips until the detent is bent out of position. The cassette is especially useful in equipment which mechanically assembles punched sheets and strips preparatory to binding a book in a binding machine.
