Abstract
The assembly includes plural independently operated rotating shafts that contact the sand fill. As the fill is introduced into a first end of the vertical chute, the speed and rotational direction of the shafts with accompanying tines are controlled to regulate the feed rate and discharge of the fill to a molding chamber. This arrangement provides a more uniform density in the molding chamber which, in turn, results in improved quality in the cast product.
