The device has a support contour adapted to a contour of plastic profiles. The support contour consists of a plain coil chain (16) that is fitted to a fitting-perimeter of the plastic profiles. The plain coil chain has a set of members (17), where each member consists of a support surface (17.1) and a wedge surface (17.2) that lies opposite to the support surface. The wedge surface supports a base frame (15) onto a counter-wedge surface. The wedge surface and the counter-wedge surface are movable from each other in relation to radial displacement of the plain coil chain. |
