Abstract
A seal for use in an extrusion device for producing continuous profiles, in particular plastics pipes includes an elastic sealing disc, which is arranged in a plane approximately perpendicularly to the extrusion direction and has a through-passage opening letting through the continuous profile and having a sealing rim bearing against the continuous profile. Connection members are arranged along the sealing rim, and clamping elements are provided for exerting a force on the connection members, with the force acting radially with respect to the extrusion axis. The clamping elements are arranged in a plane parallel to the sealing disc, have a passage opening for the continuous profile and include connecting members for connecting the connection members to the clamping elements.
