Abstract: A compact product stacker is provided for simultaneously receiving, stacking and moving a three line series of flat-shaped products. The stacker utilizes product support paddle combinations which share common, pneumatically rotated, pivot rods. The product support paddle combinations are adjustable to a downward sloping orientation, allowing gravity to assist in moving the product from an upper conveyor to the top surface of the product support paddles, at low speeds. The product support paddle combinations and pivot rods are positioned to minimize the number of required parts, to allow the lines of product to be closer together, and to minimize the width and depth of the overall device. A product alignment feature is also provided which delays the downward movement of the paddles until all products have reached their proper positions on their respective product support paddle combinations.
