Abstract
The invention relates to a calibrating device for extruded plastics sections, having a number of calibrating units 5 to 7 disposed successively in the drawing-off direction. The calibrating units 5 to 7 are mounted on a guide 1, 2 floatably in the plane normal of the drawing-off direction and disposed on the guide 1, 2, securably in the drawing-off direction. A calibrating device of the kind specified ensures that the precise positioning of the successively disposed calibrating units 5 to 7 is superfluous. Since therefore the section passes the individual calibrating units without lateral deflection or jamming, the individual calibrating unit can be designed with close dimensional tolerances, utilizing the loadability of the section, without introducing an excessive shrinkage into the section.
