Abstract: 210,445. Mumm, B. J., and Mumm, B. J. Jan. 25, 1923, [Convention date]. Sausages.-Relates to sausage-casings and a method whereby small-diameter casings are obtained from large-diameter intestines. The intestines are treated with a fat-removing solution, e.g. soda ash dissolved in water or lime water, and are then stretched on a mandrel whereby the length is increased and the diameter is decreased. As shown in Fig. 3, the former or mandrel 4 is a tube, preferably curved, and an adjustable cord 5 is anchored to the tube 4 by one or more devices comprising a hook 6 and a nut and rod 7. The cord 5 limits the circumferential contraction and is slackened after stretching and curing to facilitate the removal of the casing. The intestines, being naturally curved, are positioned with their shortest longitudinal dimension on the concave side of the former. The casing is prevented from contracting lengthwise by the friction with the former, but the ends of the casing may be clamped. The casings are cured and dried by smoke from combustion, smoke from pyro ligneous acid, alkali, acids, or fumes, after which the casings are removed from the formers.
