One of the hits of the American Textile Machinery Exhibition at Atlantic City, N.J., this week is the Pacific Evenness Tester, which Robert C. Wilkie, director of the Engineering Research Department of Pacific Mills at Lawrence, explained to hundreds of visitors at the show. With Mr. Wilkie is J. G. Anderson, (left), head of Anderson Machine Shop, Inc., the builder. The highly complex machine makes possible micrometer accuracy in measuring and recording variations in sliver and yarn uniformity in every known type of textile fibre.
