Procedure for adjusting a series of cuts shoe distributed in a range of sizes from a base cut and a cutting shoe thus obtained.

摘要

A process for manufacturing scale a series of shoe shapes distributed in a series of shoe sizes from a base shoe shape (2) provided in a basic footwear size, comprising the steps of shoe: - gathering the spatial coordinates (xB, yB, zB) of points on the base shoe shape (2) shoe basic size using gauges (15) associated with a first computer means (10) on which CAD programs are run, or obtaining said spatial coordinates (xB, yB, zB) from a storage unit (8); - obtaining, from the spatial coordinates (xB, yB, zB) of points on the base shoe shape (2) of basic size, the spatial coordinates (xn, yn, zn) of points on at least another shoe tree shoe series, using said computer means (10) provided with predetermined calculation formulas; wherein said computer means (10) equipped with CAD programs is used for defining the profile, the volume or coordinates espacialesde the footwear component parts associated with said another shoe shape in the series; and - feeding an NC tool machine with said spatial coordinates (xn, yn, zn) of points on at least said another shoe shape in the series for the manufacture thereof; - characterized in that the size of any shoe shape in the series refers to physiological length and is defined as the development of the surface of the sole in the distal direction, ie in the direction of its length, long a predetermined X axis; and that said calculation formulas link the spatial coordinates (xn, yn, zn) of points on at least said another shoe shape in the series to the spatial coordinates (xB, yB, zB) of points on the shoe last base (2) by a relation of proportionality of predetermined coefficients (cx, cy, cz) that are functions of an integer (n) denoting the positive or negative distance, or increment, in the direction of length along said X axis, a size in the range given with respect to the basic size, according to the following formulas: Cx = 1 + f (n) Cy = 1 + f (n) - f (nDo | n |) Cz = 1 + f (n) - f (nDo | n |) where | n | is the absolute value of n.
