SEAL FOR USE IN AN EXTRUSION DEVICE

摘要

The invention relates to a seal (300) for use in an extrusion device for producing continuous profiles in particular plastics pipes. In order to achieve a reliable sealing action in the case of large pipe diameters and to achieve further advantages while avoiding chattering or stick slip effects provision is made of a seal (300) according to the invention having an elastic sealing disc (326) which is arranged in a plane approximately perpendicularly to the extrusion direction and has a through passage opening (332) letting through the continuous profile and having a sealing rim bearing against the continuous profile and also has connection means (328) arranged along the sealing rim and also having clamping means (320) for exerting a force on the connection means (328) said force acting radially with respect to the extrusion axis wherein the clamping means (320) are arranged in a plane parallel to the sealing disc (326) have a passage opening (332) for the continuous profile and comprise connecting means (324) for connecting the connection means (328) to the clamping means (320).
