Abstract
397,579. Vulcanizing shoes &c. ROLLMANN, H., 223, Goltsteinstrasse, Marienburg, Cologne, Germany. March 17, 1932, Nos. 8013 and 8014. [Classes 70 and 87 (ii).] The tread sole or an intermediate sole b, c, Fig. 1, of boots and shoes for indoor wear, more especially slippers and house shoes, extends into the inside and is of macro-porous or micro-porous rubber, such as sponge rubber, secured to the upper a by vulcanization. Where the intermediate sole is of this material, an outer tread sole d, f of denser rubber or crepe rubber may be provided. Different parts b, c of the intermediate sole, or d, f, of the tread sole may be of different kinds of rubber. An integral heel g of sponge or dense rubber may be provided on the sole and a loose insole h of sponge rubber may be inserted in the slipper. The upper a, which may be of any material such as camel-hair and lined or not, is shaped on a last k, Fig. 9, and placed under pressure in a mould m containing a rubber mix which includes a raiser for producing sponge rubber. A layer of dense rubber may be placed at the bottom of the mould for the tread if desired. On vulcanization, by introducing the whole into a furnace or by heating the last internally and the sole mould externally, the upper and sole are united and the sole swells and is moulded. The sole mould is of such dimensions as to enable the mix to swell during vulcanization and may have recessed or relief patterns on its interior. The upper edge of the mould may be square, bevelled in either direction to an edge or provided with an internally projecting ledge o, as shown.
