A flat article hopper having a plurality of bottom rods to form a supporting surface for supporting a stack of flat articles and a paddle to push the flat articles towards a flat article feeder at the downstream end, A scrub wheel is rotatably mounted on a fixed, rotation axis on the paddle and is in contact with one of the bottom rods. The rotation axis of the scrub wheel is oriented at an angle relative to the rotation axis of the contacting rod, so that when the contacting rod rotates, it causes the scrub wheel to rotate, thereby producing a force on the paddle urging the paddle to move towards the downstream end. Preferably, the flat article hopper has a side rod on one side of the envelope stack, and the supporting surface is tilted from the horizontal surface, so that the flat articles are moved towards the side rod by gravity in order to register against the side rod. Preferably, the side rod also rotates in order to reduce the friction between the flat article stack and the side rod.
