ABSTRACT:
Presented is a method and apparatus for the substantial automatic folding of flat pre-cut blanks of sheet material to form storage envelopes for floppy or rigid disc storage devices. The machine includes a pedestal formed in part by an electromagnet associated with a clamp plate that constitutes an Armature to retain the sheet material immovable during the folding operation. Additionally, there are provided three rams each associated with a pivotal shoe for folding selected portions of the flat sheet, and reciprocable glue dispensing means are provided for dispensing glue at the appropriate time, in an appropriate amount, and in an appropriate location. The mechanical aspects of the apparatus are connected to and controlled by a computer that scans the functions of the machine to determine if the machine is operating properly and signals the operator through an alphanumeric display panel if there is a malfunction in the apparatus.
