A continuation of a Textile Mercury (24 August 1889) trade notice describing an improved revolving-flat cotton carding engine by John Hetherington and Sons of Manchester. It explains the flexible-bend trueing machine that restores the concentric bends after wear, and the patented grinding apparatus that grinds flats from their working surfaces, with a cam wheel, star wheel and grinding roller. It also covers a differential slow-grinding apparatus that can be fitted to existing cards. Six figures illustrate the mechanisms.
