Abstract (en)
[origin: EP0099744A2] In Conform machinery for continuous friction actuated extrusion the wheel is made up of at least three parts, namely two cheeks with a hub between them. Annular coolant passages extend between these members and are fed by ducts (6, 8) which extend at least through the cheek members. These ducts, and any extending through the hub are lined with thermally-insulating material (10) such as PTFE. This greatly reduces thermal stresses around the coolant ducts, which can be a cause of premature and catastrophic failure of the wheel.
