DEVICE FOR COOLING AND CALIBRATION OF EXTRUDED PLASTIC SECTIONS |
摘要 |
The invention relates to a device for cooling and calibrating extruded plastic sections, comprising dry calibrators arranged behind an extruder with a nozzle connected downstream. Shorter dry calibrators (1-5) than the conventional calibrators are used in the device according to the invention, a water bath (6-9) being arranged in each case between two dry calibrators. The shorter dry calibrators (1-5) can also be manufactured economically to have a conical shape of the inner profile, thereby resulting in particularly low tension in the extruded section just like the water baths (6-9) therebetween. |
