Procedure for making rubber soles with coloured inserts for sports shoes, mould for effecting such procedure and soles made by it

摘要

This procedure for making rubber soles with coloured inserts for sports shoes, in particular for football, uses moulds that have areas with wrinkled surfaces, obtained by sanding, by a chemical process or by mechanical production, which prevent the coloured inserts (3)from slipping up beyond the limits (7) set for them around the heels (2), creating a very much more attractive sole with no weak points around the heels (2) (Fig. 1).IMAGE
