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.
Claims14
In a method of feeding cards or like paper stock singly from a stack thereof, using a friction wheel positioned above a movable platform to feed the cards singly from the bottom of the stack forwardly onto the platform from the stack and to pass the cards singly through a gap between the friction wheel and the platform to issue therefrom, the step of:
- rotating the friction wheel sequentially through preselectable arcs whereby the issuing cards are optimally spaced apart.
In a device for feeding cards and like paper stock singly from a stack thereof, in which a friction wheel is positioned above a movable platform and the cards are fed singly from the bottom of the stack through a gap between the friction wheel and the platform to issue therefrom:
- a stepping motor connected to drive the friction wheel;
- and
- means connected with the stepping motor to control the rotation of the friction wheel sequentially through preselectable arcs whereby the issuing cards are optimally spaced apart.
