Abstract

A plastisol composition for use in the moulding of shoe soles comprises polyvinyl chloride 57,7, dicapryl phthalate 27,4, aromatic oil 9,6, white lead paste 2,4, and a 1:1 dispersion of SRF Black in dicapryl phthalate 2,8 parts by weight. The insole and the inturned margin of the upper may be coated with a primer comprising butadiene-acrylonitrile copolymer rubber 100, hydrated amorphous silica 10, maleic anhydride vinyl chloride/acetate terpolymer 100, and natural rosin 20 parts by weight, together with methyl ethyl ketone in quantity sufficient to dissolve the polymers and give a primer of appropriate viscosity. Specification 859,671 is referred to.ALSO:A blank of gelled thermoplastic material, e.g. polyvinyl chloride, is heated to render it mouldable, positioned in an unheated mould of a press (such as that described in Specification 859,671) forced while still hot into engagement with a shoe bottom in order to mould the blank against the shoe bottom to form a sole and heel unit of a required shape and to cause it to adhere to the shoe bottom, and the shoe finally removed after the plastic material has cooled to a shape-retaining condition. The blank comprises a plane upper surface and a smoothly rounded, highly polished, blemish free surface extending over its side and lower portions and is made by pouring plastisol, comprising 57,7 to 62,5% by weight of polyvinyl chloride and up to about 10% by weight of a non-plasticizer as an extender dispersed in a plasticizer, into a highly polished, blemish free mould, and then gelling by heating to between 170 DEG and 185 DEG C. before positioning in the press mould.
