ABSTRACT:
A method and system are provided for forming floppy disk envelopes. Envelope blanks are manipulated while attached to a continuous web of envelope material to facilitate handling and alignment of the blanks. Initially, fold lines are impressed into the envelope blanks to define the precise dimensions of the envelope. Envelope flaps are then partially folded to define a receptacle into which the disk media is then inserted. The remaining flaps are then folded and sealed, and lastly the folded envelope is detached from the continuous web. A particular apparatus for impressing the envelope blanks includes a male die, female die cavity, and mechanism for reciprocating the dies. The preferred score profile includes a pair of radii joined by a hinge section.
