Abstract

Procédé et dispositif permettant un chargement et un dosage de gomme automatiques. Le procédé consiste à utiliser une machine à injecter oléopneumatique du type à pot et piston dans lequel un compactage de la gomme est réalisé préalablement à l'injection, le dosage de la matière étant réalisé grâce à des butées extérieures réglables sur une tige solidaire du piston et un capteur du niveau de matière commandant l'alimentation automatique en matière. Application : presses à injecter destinées au moulage des produits en caoutchouc.
