EJECTION FINGER A sorting machine for separating substandard items from a continuous stream of products is disclosed wherein the ejector means for removing the detected substandard items includes an ejector finger of monolithic structure and homogeneous material and an actuator. The ejector finger includes a base fixedly attached with respect to the product stream, a contactor normally withdrawn from the product stream when standard products are in the stream and for entering the product stream to eject a detected substandard item, and a hinge of reduced dimension connecting the ejector finger base to the ejector finger contactor. The hinge is biased to normally withdraw the ejector finger contactor from the product stream. The actuator flexes the ejector hinge to move the ejector contactor so that it enters the product stream for ejecting each detected substandard item. The monolithic structure and homogeneous material are resistant to wear from environmental conditions.
