ABSTRACT:
A calibration device for calibrating extruded continuous profiles, in particular tubes, includes a housing and a plurality of segment bodies which are received in the housing in a substantially in circular manner, with axially neighboring segment bodies partially overlapping in a circumferential direction. Each segment body is made from a single-piece workpiece and has a contoured inner surface, wherein the inner surfaces of the segment bodies jointly define a calibration opening for passage of a tube. An operating device retains the segment bodies in the housing and allow adjustment of each segment body in radial direction.
