Two-page article from The Textile Mercury (24 January 1891) describing the new patented slubbing, intermediate and roving frames made by John Hetherington and Sons, Manchester, with front and back view engravings. It discusses the naming of these cotton preparatory machines and details improvements: larger cones, a self-adjusting cone strap, a lever-balanced top-rail, a revised differential motion, and a new shortening and reversing motion for the builder rail. It also includes short notes on a steam-powered embroidery machine from Saurer of Arbon, Switzerland, and on the 1891-92 Palermo national exhibition.
