Abstract: A method and apparatus for controlling a flow of a product over a product attrition bed, where the product comprises a plurality of product units, for example, potatoes. In one aspect, apparatus comprises a product attrition bed and an auger positioned above the product attrition bed. The auger comprises a flow restriction mechanism to restrict a discharge flow of the product from the auger. In a second aspect, the method comprises feeding the product to the auger to provide a product charge; substantially confining the product charge in a charge space; rotating the auger to move the charge space, and thereby the product charge, in the flow direction; and discharging the product charge from the auger through a flow restriction mechanism. In a third aspect, the method and apparatus controls the feed of product to the auger, for example, providing one control volume of product per revolution of the auger.

Abstract: A blade gap setting device for a potato chip cutting head, the device comprising an elongate body having an upper surface and a lower surface, at least one mounting for a depth micrometer having a displaceable spindle, the mounting extending from the upper surface to the lower surface to permit a depth micrometer to be mounted to the upper surface with a free end of the displaceable spindle being exposed at the lower surface, a first lower reference surface and a second front reference surface, at least the second front reference surface being located forwardly of the at least one mounting.
