FIELD: shoe industry, in particular, manufacture of shoes with molded sole. SUBSTANCE: method involves assembling work piece composed of top part with face cover and stitched-in inner sole; putting bulky work piece onto extensible block; bringing halves of mold together; injecting melt mixture for injection molded attachment of shoe bottom part to flesh side of leather of shoe top part owing to flowing of melt mixture into base during attaching of shoe bottom part by molding, with the result that under pressure of melt mixture, outer layer of top part is forced against inner surfaces of mold halves to provide for pressurization of mold cavity, with top part of work piece having layer; during assembling, squeezing outer portions of top part, which are made shorter on their lower edge, by means of mold half jaws and pressing to inner surfaces of mold halves; stitching lower edge of outer shortened portions of top part to layer at the level above mold half jaw joint line, with stitched-in inner sole being stitched to layer. In the process of attachment of bottom part by molding, melt mixture flows into base between outer shortened portions of top part and layer. Method is most suitable for stitch-mold type shoes manufactured from leather with surface having low adhesion to material of shoe bottom part. EFFECT: simplified manufacture method and reduced consumption of shoe top part material. 2 cl, 3 dwg |
