ABSTRACT:
A calibration device for calibrating extruded continuous profiles includes successively arranged segment rings comprised of individual segments whose internal surfaces jointly form a calibration opening. Successively axially arranged segments are assembled in the form of a segment block. The segments of each segment block are arranged on a support structure and the segment blocks are arranged, in an essentially circular form, in a housing such that the axially adjacent segments partially overlap. Each support structure is connected to a mounting and operating device by which the individual segment blocks are fixed to the housing. Adjustment of each segment block is carried out in axial direction. The mounting and operating device is divided into two parts, wherein a first part is connected to the support structure, and a second part is received in the housing, and the two parts are connected with one another in a separable manner.
