Abstract
Rotary forming drums that have a unique vacuum distribution and control system imparting a vacuum to the insert trays in a region or zone of the drum in a controlled manner. The rotary drum also has insert trays that are forced outward by the movement of follower cam activation upon a roller cam which in turn forces molded articles from the trays quickly, cleanly and efficiently. Once the product is removed from the insert trays internal and external springs return the insert trays to their original position to repeat the process on a continuous basis.
