ABSTRACT:
A metering hopper which utilizes an oscillating friction pad to engage and initiate the feeding of successive, bulky newspaper sections or the like from the bottom of a stack may be converted into a machine using a vacuum separating feeder for thin, single-sheet articles by disabling the rocker pad assembly and bolting in place a tray module having an essentially self-contained oscillating vacuum sucker head assembly. When the tray is installed, the self-contained oscillating mechanism for the sucker head assembly makes operable engagement with pre-existing drive means on the machine so as to carry out the necessary rocking action of the sucker heads in timed relationship with other functions of the machine. Connecting the sucker assembly to vacuum control mechanism and a source of vacuum pressure completes the conversion. Separation of the lowermost article from the next higher article is carried out by causing the sucker heads to adhere themselves to the bottom surface of a leading marginal edge of the lowermost article, bend such marginal edge downwardly away from the rest of the stack, and present the edge to awaiting, high speed delivery nip rollers which take control of the article and finish its withdrawal from the bottom of the stack.
