Por tal razón, se requiere diseñar un It requires dilatation or the magnitude of the pressure to be exerted. Therefore, in most cases, it is not possible to fully satisfy the user who wears the footwear. For this reason, it is required to design a

On the other hand, the actuation means of the extruder means comprise an endless screw and crown transmission, where said crown transmits rotary movement to a tractor bar with a threaded portion that transforms the rotary movement that it receives from the crown into linear movement of the extruder means .
Así, es posible mover, con independencia y precisión, cada uno de los medios extrusores de la horma contra determinadas zonas del corte del calzado, aplicando presiones específicas sobre cada una de dichas zonas que se corresponden con la forma particular del pie del usuario. Thus, it is possible to move, independently and accurately, each of the last means of the last against certain areas of the shoe cut, applying specific pressures on each of said areas that correspond to the particular shape of the user's foot.
Por ejemplo, los movimientos de cada uno de los medios extrusores contra las correspondientes zonas concretas del corte del calzado pueden ser comandados por un microcontrolador que accione sobre sendos motores eléctricos, uno para cada medio extrusor, a partir de parámetros de avance obtenidos en un ordenador al procesar información recibida de un escáner For example, the movements of each of the extruder means against the corresponding specific areas of the shoe cut can be commanded by a microcontroller that operates on two electric motors, one for each extruder means, from advance parameters obtained in a computer when processing information received from a scanner
