Abstract

Dispositivo de accionamiento del aire de aspiración para máquinas ajustadoras de pliegos , especialmente para dispositivos colocadores de fondos de máquinas productoras de sacos, con aspiradores que elevan individualmente los pliegos y van unidos por medio de una válvula de tres vías accionada con un generador de vacío, caracterizado porque la válvula de tres vías (1) lleva una cámara conectada con el aire exterior, y otra con el generador de vacío (15,12) , que están unidad alternativamente con la línea (10, 11) que conduce a los aspiradores (8) por medio de un plato de válvula (13) y que está accionado por el movimiento de transporte de vaivén de los aspiradores (8), caracterizado también porque el plato de válvula (13) es impulsado por un resorte (17) que con la cámara de aire de aspiración (12) no pueda vencer la fuerza de aspiración que actúa sobre el plato de válvula (13) y que, con la cámara de aire exterior cerrada (15) , cuyo diámetro es inferior al de la cámara de aire de aspiración (12) , mantiene el plato de válvula (13) contra la presión del aire exterior en la posición en la que cierra herméticamente la cámara del aire exterior (15).
