INNER COOLING BODY FOR A BLOWN FILM EXTRUSION LINE, BLOWN FILM EXTRUSION LINE COMPRISING SUCH AN INNER COOLING BODY AND METHOD FOR OPERATING SAID BLOWN FILM EXTRUSION LINE |
摘要 |
The formation of paraffin condensate on an inner cooling body of a blown film extruder can be either avoided or allowed in a controlled manner and then removed, thereby reducing damages to the film tube or even avoiding them. In an inner cooling body for a blown film extrusion line, the inner cooling body includes a shell around which a blown film tube, coming from the annular die, can ascend against gravity or can descend with gravity when the blown film extrusion line is running. The shell has a fraction condensate diverter for keeping paraffin condensate or any other condensate away from potential contact points of the blown film tube on the shell. |

1. An inner cooling body for a blown film extrusion line, said inner cooling body comprising a shell, around which a blown film tube, coming from an annular die, ascends against gravity or descends with gravity when the blown film extrusion line is running, wherein the shell has a fraction condensate diverter configured to keep paraffin condensate or any other condensate away from a plurality of potential contact points of the blown film tube disposed on the shell that protrude radially outwards on the inner cooling body. |
