ABSTRACT OF THE DISCLOSURE Short multi-ply business forms, or other flexible planar articles, are stacked with a vertical orientation in a horizontally elongated stack. The forms are conveyed in a first horizontal direction, then deflected by a deflecting roller and conveyor belts to move toward a generally vertical orientation, and driven vertically into contact with a depth stop, so that they have a vertical orientation and the first form in a stack is against a backstop. The backstop is moved intermittently in the horizontal first direction to accommodate further forms in the stack. A conveyor for moving the forms vertically is mounted for pivotal movement about a generally horizontal axis, which movement is sensed by a sensor which in turn, through a controller and motor, effects intermittent movement of the backstop. The depth stop may be adjusted to accommodate forms of different depths, and the position of the horizontal axis about which the second conveyor pivots may also be adjusted. The pivoting vertical conveyor applies a packing force against the forms in the stack, and its center of gravity is between its pivot axis and the stack at all times.
