Abstract

1,214,738. Moulding shoes. RIEKER & CO. 5 July, 1968 [16 Dec., 1967], No. 32313/68. Heading B5A. Shoes of several different successive foot sizes are produced using an apparatus comprising an outer mould formed of two parts 1 and 2 and having fixed inner cavity dimensions and a core 3 within said cavity having outer dimensions the same as the shoe size to be produced. The core 3 is surrounded by a moulding cover 5 attached to the core 3 by elastic bands 4, the cover 5 being inflatable (shown in inflated position in Fig. 2). In use the outer side of the cover 5 is applied upon a lining bag 10, for example of leather, which is of a general shape similar to the core 3 and corresponds to the inner shape and dimensions of the boot to be made. This lining bag 10 is secured at points 11 to reinforcing layers 12 and 13. The cover 5 is then inflated, so expanding the lining bag and pressing it firmly against the reinforcing layers. Moulding material is injected into the space between the outer mould and the cover 5, lining bag 10 and layers 12 and 13 to form the outer layer 6 of the upper and the outer sole. The pressure in cover 5 is then reduced so that it and the lining bag 10 are drawn back on to the core 3 by the elastic bands 4, leaving chambers 8<SP>1</SP> and 811 between the lining bag 10 plus the core 3 and the outer layer of the upper which are then filled with moulding material by injection to form filler layers. The size of the total core is varied by inflating the cover 5 to different extents. Two solid cores of different sizes may be used instead of a core and moulding cover. The moulding material used is plastics material or rubber. A vacuum instead of elastic bands may be used to draw the cover 5 back on to the core 3.
