  • Both the calendering rollers and the forming rollers constitute precision parts, of important cost and maintenance, that have a negative impact on the profitability of the process.

  • the method of the invention based on a continuous extrusion phase and application when necessary of a laminar envelope, unavoidable phases and in the public domain, focuses its characteristics on the fact that the conformation of The profiled part is carried out in a molding phase by intermittent pressing and simultaneous cooling, then the profile is continuously subjected to a cutting phase and the final cooling thereof.

  • the installation has the peculiarity that the corresponding press It incorporates two clamps or jaws that act perpendicularly to each other, so that in the closing situation they detect a te ⁇ ninal envelope for the slat of material, ensuring a perfect formal and dimensional stability for said slat, while the cooling phase of the same is taking place in The bosom of the press.

Abstract

A partir d'une extrudeuse classique (1), on obtient une bande de matériau (7) qui constitue le noyau des pièces profilées à obtenir. A la sortie de l'extrudeuse, cette bande de matériau reçoit un revêtement ou enveloppe (3-3') fourni par une paire de bobines (4-4'). La bande de matériau revêtu (7) passe ensuite dans une presse d'actionnement intermittent (9-11) qui donne à la bande de matériau (7) son profil définitif et qui est mobile dans le sens longitudinal de façon que ladite presse d'actionnement gagne une position de fermeture en accompagnant la bande de matériau (7) à la même vitesse à laquelle cette dernière est déplacée par un dispositif d'entraînement (16) situé plus loin et que ladite presse d'actionnement recule brusquement de façon à gagner une position d'ouverture afin de traiter un nouveau tronçon de bande (7).
