Abstract: A method of removing product of an unacceptable height from a product line is disclosed. In the method, a quantity of the product is arrayed in a carrier and moved to a gauging station where the array is placed between a reference plate and a corresponding array of gauging members and gauged by raising the reference plate to a predetermined height position and measuring the height of the gauging members when the gauging members are supported on the product array. The signals from the gauging station are stored and the carrier plate is moved to a rejection station where unacceptable product is selectively removed in response to the stored rejection signals from the gauging station. The carrier plate is then returned to the product line with only acceptable product still in place.
