DEVICE FOR SEALING A COOLING TANK FOR AN EXTRUDED PLASTIC PROFILE |
摘要 |
A device for sealing an extruded plastics material profile in at least one of an inlet region and an outlet region of a tank is disposed at an end face of the tank. The device includes a rigid element and a closed annular cross section formed of a resilient material and including a cavity. An outer peripheral shape of the annular cross section is disposed against the rigid element. The annular cross section is alterable by applying a vacuum to the cavity, wherein the annular cross section is configured to be applied to an outside of the plastics material profile. A stretching device is disposed against the rigid element and is configured to stretch the resilient material along an extrusion axis during an alteration of the annular cross section. |
