Embodiment Construction

[0031] like Figure 1-5 As shown, the process of the present invention firstly involves the preparation of a novel shoe insole 1, which has the characteristics of light weight, softness and high elasticity.

[0032] Preferably, said insole 1 is made of a piece of thin leather or soft thin tanned leather or even fabric or cloth. The insole 1 has a top surface A and a bottom surface B. A strip 2 is sewn onto the bottom surface B along the entire edge of said insole 1, except for the horseshoe arched sole, whose edge wraps around the heel. Wherein the rubber strip 2 is also made of a piece of thin leather or soft thin tanned leather.

[0033] More specifically, the rubber strip 2 is fixed on the lower inner sole 1 by at least one edge stitch C1, wherein the stitch C1 is close to the outer edge 2a of the rubber strip 2. By setting the outer edge 2a at a position flush with the edge 1a of the insole 1, the inner edge 2b of the rubber strip 2 is freely closed and separated from t...

Abstract

Machining process for the manufacture of an insole for footwear, having a tape (2) at the bottom face (B) of the insole (1) and around < the entire periphery thereof, except only for that horseshoe arch that surrounds the heel of the shoe if desired, the outer edge (2a) of said tape being attached to and aligned with the edge (1a) of the insole (1) so that the inner edge (2b) of said tape (2) is free to be folded and detached from the bottom face (B) of the insole (1), said process including the following operational steps: cutting the insole (1) along a plane parallel thereto so as to open the insole from the tip to the plantar arch, dividing it into a top half-insole (1c) and a bottom half-insole (1d); fixing said tape (2) beneath the bottom half-insole (1d) so that the outer edge (2a) of said tape (2) is fixed to and aligned with the edge (1e) of the bottom half-sole (1d), while the inner edge (2b) of the tape (2) is free to be folded and detached from the bottom half-insole (1d); inserting a padding layer (5) between the two half-insoles (1c and 1d), which are then laid down and glued peripherally one on top of the other, to form a sandwich structure together with the intermediate layer (5).

Description

technical field [0001] This industrial invention patent application relates to a shoe insole processing technology, in particular to a method for producing shoe interiors by the "Good Year" method. The present invention also relates to a novel shoe inner sole manufactured according to the processing method of the present invention. Background technique [0002] In the production of so-called "pre-assembled" footwear, the upper, before being joined to the sole, is pre-assembled by means of a last, according to a known and established process called "Good Year". on the insole. [0003] More specifically, according to the above process, first an upper is prepared, which is designed to wrap around the foot and the top of the foot. Since the upper of a shoe is designed to be installed on the insole, the bottom of the upper of a shoe is open and wraps the entire edge of the sole; an outsole is arranged below the insole. [0004] As already mentioned, the "pre-fitting" of the up...
