| titleOfInvention | Improvements in or relating to methods of providing shoes with moulded shoe bottom members |
| abstract | 780,017. Moulding shoe soles. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Nov. 10, 1955 [Nov. 11, 1954], No. 32624/54. Class 87(2). [Also in Group VII] A method of moulding a shoe sole onto a shoe bottom comprises providing the shoe with a downwardly extending peripheral wall which is held against a moulding member while a resin dispersion is injected, heated, and allowed to solidify to form the sole. A shoe 10 has a wall or welt strip 16, notched at 22, which is stuck round the periphery of the insole 14. The wall is held in fluid tight contact with the contoured surface 30 of a moulding plate 26 while a fluid dispersion of resin particles in a liquid plasticiser is injected into the cavity formed on the shoe bottom either through an inlet 36 or a temporary opening in the wall 16 or in some cases in the insole or sock 14. The assembly is then heated by a hot plate, heating chamber, heating cartridges or the application of a high frequency electric field to solidify the sole bonding it to the insole 14 and to the upper by means of the wall 16. Suitable resins are copolymers of vinyl-chloride and vinyl acetate, polymethyl methacrylate and vinyl chloridevinylidene chloride copolymers. Suitable fillers, dyes or pigments may be used. Prior to the injection of the plastic the insole may be coated or impregnated with a suitable thin fluid resinous material such as resin latex. The wall may be of conventional leather or vinyl welting material grooved to simulate stitching or preferably a plasticised resin strip is used which becomes integral with the solidified sole. If a separate heel is to be applied to the sole a step is provided in the moulding surface against which the ends of the wall 16 are abutted at about the heel breast line. |
