摘要： Apparatus for feeding cards sequentially from the bottom of a card stack including a pair of rolls, which may be termed a feed roll and a second roll, and having a friction belt passing over them with the feed roll being rotatably mounted on an arm which is pivoted on the center of rotation of the second roll so that the friction belt may be moved into forceful contact with the bottommost card of the stack on pivotal movement of the arm. A friction brake is provided for the feed roll, and the second roll is driven so that the friction belt in the vicinity of the feed roll is moved into contact with the bottommost card of the stack without any rotation of the feed roll about its own axis; and, subsequently, the force from the friction belt on the feed roll causes the feed roll to rotate about its axis with corresponding movement of the friction belt so that the belt displaces the bottommost card from the stack.
