A stacking machine includes a pair of gripping jaws that are openable and closable to grip a leading edge of an article and move it to a stacking position. The jaws are moved between a gripping position and a release position by a fluid cylinder assembly and are automatically moved to an intermediate position when the jaws are moved to receive an article. Air flow is used to straighten the trailing part of the article on the stack. The gripping jaws are moved between an article receiving position and an article discharge position by a pneumatic cylinder assembly that will accommodate variations in stack height.
