Abstract

1,130,729. Boots &c. A. SAUER. 11 May,1966 [11 May, 1965; 28 Jan., 1966], No. 20819/66. Heading A3B. [Also in Division B5] A combined heel and shank assembly 2, 3 is moulded in a single piece from a hard, elastic plastics material e.g. polypropylene or a polyamide. In a first embodiment (Fig. 7) the heel-shank assembly 2, 3 is secured by a screw 14 to an insole 11, the insole being positioned by projections 13 on the heel seat engaging apertures in the insole. The lasted upper is then transferred to a metal last 15 and is positioned over a mould 17, 18, 19 where the shoe is provided with a sole 20 and heel cover 19 e.g. of rubber or p.v.c. which is injected into the mould through a duct 21. The shoe is completed by the addition of a leather top lift. In a second embodiment (Fig. 2) the heel-shank assembly 2, 3 is placed in an injection moulding machine where a complete shoe, including upper, insole, sole and heel cover, is moulded on to the assembly. In order to provide a key with the injected material the upper surface of the assembly is provided with alternately arranged apertures 4 and projections 5 and the rear surface of the heel is provided with ribs 6.
