摘要： A device for forming a hollow profile formed as a multi-chamber profile by an internal high pressure generated by a fluid pressure medium within the hollow profile containing a sealing die engaging in the profile chamber with a carrier part and a collar arranged on the carrier part sealing the face side of the profile chamber. The die also has a passage opening as a pressure medium supply and/or extraction channel. The collar is a resilient rubber die part arranged on the face of the carrier part facing the profile chamber and on the free face of the collar is provided a preload plate which is anchored by way of the fixing member penetrating the collar in the carrier part lying on the collar so that the collar is squeeze-clamped between the preload plate and the carrier part.
