Abstract

Machine avec un cylindre partagé en une zone d'introduction avec une ouverture d'entrée, une zone de pressage et une zone d'expulsion de matériau plastifié, et contenant une vis sans fin de plastification, une poche d'introduction étant prévue dans le cylindre dans le domaine de l'ouverture d'entrée. Machine caractérisée en ce que le profil du corps de filet 20 de la vis sans fin de plastification 12, a une forme triangulaire, au moins dans le domaine de l'ouverture d'entrée 16, la crête des filets étant constituée pour favoriser une action de tranchage du matériau. Machine applicable au traitement de matériaux bruts en bande tels que du caoutchouc.
