Stötteanordning og fremgangsmåde til ændring af en stötteanordnings stötteområde

摘要

The shape of the supporting area(1) corresponds to that of the plastic profile and has a variable radius. The support comprises a row of plates(5) with different radii which can move around a common rotation point(6). Individual plates may be connected to each other in the supporting area(1) to form a common surface with a continuously changing shape. The support may alternatively be a one-piece component and each section through a common rotation point has a different radius so that the shape is continuously variable. An electrically operated adjuster moves the support around the rotation point and has a mark which indicates the radius which has been set. An independent claim is included for a method for varying a supporting area of the profile support to suit a particular diameter in which the position of the one or more supports is altered so that the appropriate diameter profile is set to the operating position.
