Abstract

La présente invention concerne un procédé pour le calibrage de tronçons de tubes de verre selon lequel on fait chauffer un tronçon de tube de verre à une température de ramollissement pour le façonner à la mesure de calibrage et qu'on laisse refroidir. Ce procédé est caractérisé par le fait que dans le tronçon serré aux deux extrémités le verre, ramolli à l'endroit du façonnage, est pressé contre une surface externe ou interne de calibrage par une pièce de façonnage guidée hélicoidalement à l'intérieur ou à l'extérieur du tronçon, par rapport à celui-ci. L'invention concerne aussi un dispositif pour l'application du procédé qui comprend des moyens de serrage du tronçon, des supports mobiles portant respectivement une pièce de façonnage et une surface de calibrage constituées par des galets, ainsi qu'un brûleur.The present invention relates to a method for the sizing of sections of glass tubes in which a section of glass tube is heated to a softening temperature to shape it for the calibration measurement and allowed to cool. This process is characterized by the fact that in the section clamped at both ends the glass, softened at the place of shaping, is pressed against an outer or inner sizing surface by a shaping part guided helically inside or out. 'outside of the section, relative to it. The invention also relates to a device for the application of the method which comprises means for clamping the section, movable supports carrying respectively a shaping part and a calibration surface formed by rollers, as well as a burner.
