Abstract: A rotary tool ejection technology utilizing air to eject contents from the dies of a rotary cylinder. The dies include orifices positioned therein. The orifices are assembled with porous material. The orifices are capable of receiving air from an internal chamber and delivering it to the outer surface of a rotary cylinder. Air is supplied to the internal chamber by an internal shaft. The internal shaft contains a channel in fluid communication with outlets extending radially outward from the channel to locations on the outer surface of the shaft. The shaft is optionally assembled with a manifold having a conduit. The conduit is positioned for intermittent alignment with the orifices in the rotary cylinder as the rotary cylinder rotates relative to the manifold.

Abstract: A rotary molding apparatus has a die roll and a split clamping pillow block structure of self-centering structure supporting the opposite shaft ends of the die roll. The split pillow block has a pivotally mounted portion and a device for locking that portion when the die roll is in operation. A feed roller is mounted on upright arms which are urged toward the die roll. The arms carry doctor blade structure between the feed roller and the die roll and the doctor blade is biased toward the die roll. A fluent material supply hopper cooperates with the feed roller and there is a guide structure for effecting movement of the hopper between the feed roller cooperation position and a backed-off position. A magazine is provied for storing a plurality of die rolls and a mechanism is provided for selecting any die roll from the magazine and for transporting such die roll from the magazine into working position in the pillow blocks and for selectively returning the die roll to the magazine.
