Part XXI of a series on the textile industry at the 1873 Vienna Exhibition, by Dr. H. Grothe, covering embroidering machines. It describes Heilmann's large flat embroidering machine built by the Sächsische Stickmaschinen-Fabrik at Kappel near Chemnitz, including its double-pointed needles, sliding frames and the pantograph-style lever system that follows a pattern drawn six times full size. It also covers single and quadruple tambouring (chain-stitch) machines and a pattern-pricking machine, with engravings of each.
