Abstract:
1. A machining process for manufacturing an insole for footwear, a tape being provided at a bottom face of the insole around an entire periphery of the insole or with exclusion of an horseshoe arch surrounding a heel of the footwear, an outer edge of said tape being attached to and aligned with an edge of the insole so that an inner edge of said tape is free to be folded and detached from the bottom face of the insole, the process comprising the steps of: cutting the insole along a plane parallel to the insole so as to open the insole from a tip to a plantar arch, dividing the insole into a top half-insole and a bottom half-insole; fixing said tape beneath the bottom half-insole so that the outer edge of said tape is fixed to and aligned with an edge of the bottom half-sole, while the inner edge of the tape is free to be folded and detached from the bottom half-insole; and inserting a padding layer between the top half-insole and the bottom half-insole, said top half-insole and bottom half-insole being then laid down and glued peripherally one on top of the other, to form a sandwich structure together with the padding layer.
