ABSTRACT:
A stacking and delivery apparatus for stacks of products such as paper napkins and paper towels includes a magazine into which the products are delivered to form stacks and which supports the stack along a path of product movement. A plurality of fingers are mounted on a conveyor adjacent the magazine, and the conveyor moves a finger into the path of stack movement when a stack is completed and separates the completed stack from the next stack. A drive system for the conveyor moves the conveyor at different speeds during each cycle in which a stack is formed--a first, fast speed at which a finger is quickly moved into the path after a stack is completed, a second, relatively slow speed at which the finger moves the completed stack along the path as the next stack is built up behind the finger, a third, relatively fast speed at which the finger moves the completed stack rapidly along the path, and a fourth speed, which can be zero, during which a completed stack is removed from the conveyor.
