SYSTEM OF CONTROLLED SHOE UPPER SIDES LASTING PROVIDING RETAINING OF THE SHOE UPPER TOPLINE POSITION

摘要

A system of controlled shoe upper sides lasting, consisting of four lower cylinders (10), two compression cylinders (3), bearing a properly shaped base (9) fixed on their end rods, for housing of four cylinders (1) by means of another base (2) acting as a guide, said base (2) bearing internally a controlled pressure elastic tubular means (4) and an rubber mold (8) of general shape placed in between them, suitable of being embedded in various types of machines and for all shoe uppers types, characterized in being capable of applying a sectional millimetric compression on the shoe upper materials, by holding the top line (11) at the sequence starting and by applying an increasing pressure-compression until the full enclosing of the last is achieved up to point (14), thus said process providing an ideal upper materials/last proximity and retaining of the shoe upper top line level nature and desired position with no shoe upper distortions, wrinkles etc. being created.
