ABSTRACT:
The instant invention provides an apparatus and method for reliably separating a selected sheet from a spaced array of sheets transported on a conveyor. The invention continuously maintains vacuum on the conveyors, and uses selectively activated jets directed at the underside of the sheets to divert them for separating. The invention positively controls the destination of discrete, flexible sheets, such as photographic film, by continuously engaging the sheets with another conveyor during separating, sorting, shuffling or the like, as they travel in an array along a conveyor. Positive control of the sheets permits reliable, high speed separating of lightweight, flexible sheets.
