Abstract
An apparatus for continuously varying the position of an article carrying platform in response to an inflowing stream of articles placed on the platform. The platform positioning apparatus finds use as part of a vertical stacking machine which stacks an inflowing stream of signatures on the platform. It has a position sensor for detecting the position of the platform and providing a platform position signal to a controller. A controller issues a translation signal to a translation motor responsive to the platform position signal. The translation motor causes the bidirectional translation of the platform responsive to the translation signal from the controller.
