ABSTRACT:
The present invention is directed to a vertical stacking system comprising an apparatus and method to control stack formation based on a non-contact sensing of the reaction of the feed conveyor to the forming stack. In accordance with the invention a stream of signatures is fed by the feed conveyor onto a support surface. There is an upper feed extension of the feed conveyor located above the support surface. The stack is formed between the support surface and the feed extension. The top of the stack is adjacent to the upper feed extension. The location of the extension is determined by the location of the top of the stack. The non-contact sensing means senses the location of the feed extension and generates a location signal. This location signal is used to control a slide drive which moves the support surface.
