Abstract
Abstract Covers for floppy discs and like media are first formed with three sides sealed and thereafter the disc is inserted. A fourth flap must then be folded and glued for permanent sealing of the disc. The subject machine receives the unsealed cover with the disc inserted and folds and glues the flap to seal the disc in the cover.
