A technique is described whereby an elevator-leveling apparatus is used in conjunction with an automatic feed mechanism during the fabrication of 5-l/4-inch diskettes. The apparatus provides a self-leveling concept so as to ensure that diskettes are always in a horizontal position for each pick-up by a pneumatic head. In the construction of 5-1/4-inch diskettes, the rear edge of the diskette is required to be thicker than the front edge. As a result, a stack of 100 diskettes will cause the rear edge 10 to be thicker than the front 11, as shown in the figure. This presents a problem when automatic pneumatic pick-up mechanisms are used to pick-up diskettes one at a time, since the pick-up mechanism requires the diskettes to be horizontal for proper operation. As a result, a self-leveling mechanism was devised.
