Calibration and cooling device for extruded plastic hollow sections, which has several Kalibriersegmente (5,6,7) with - the desired profile corresponding - openings (13). To the inner walls lead with a vacuum source related channels. The Kalibriersegmenten (5,6,7) is a water tank (1) arranged downstream, are arranged in the support plates (10,11,12), the openings correspond to the outer contour of the hollow profile. The water tank (1) is closed and has a free space (4), which communicates with a vacuum source. In order to enable a simple construction of such a device, it is provided that only that calibration segment (5), which is first penetrated by the hollow profile to be calibrated, connected to a separate cooling circuit and provided with its own connection to a vacuum source and that the remaining Kalibriersegmente (6,7) in the water tank (1) are arranged. |
