FIELD: regulated devices for calibration of extruded endless sections, particularly tubes.
SUBSTANCE: device is provided with calibration opening formed by means of large number of segments arranged along circle and regulated along radius. Each segment has segment body. Inner surfaces of segments form together calibration opening. Each segment body has at least one actuating unit for holding separate segments. Actuating unit provides regulation of each segment body in radial direction. At least one mounting ring is arranged in circumferential direction and it has radial holes whose number corresponds to that of segment bodies. Said actuating units are introduced into said holes and they are fixed in them at desired orientation. In each hole there is its own mounting member for accurately orienting respective actuating unit.
EFFECT: simplified manufacture of easy-to-mount calibration device that may be accurately oriented and regulated.
