Abstract
A method and a device for controlling the issuance of cards or like paper stock singly from a card feeder having a friction wheel which is positioned above a movable platform to feed the cards singly from the bottom of a stock. The friction wheel is rotated sequentially through preselectable arcs, intermittently if desired, whereby the issuing cards are optimally spaced apart. An auxiliary feed mechanism operating at a preselected speed and intermittently if desired may assist feeding the bottom cards of the stack as they are moved towards the nip between the friction wheel and the feeder platform. An advancer mechanism may assist movement of the stack towards the feeder platform, the stack advancer being movable sequentially at a preselected amount and preferably intermittently.
