Abstract: A stretch rolling method and a stretch rolling unit can roll out any gripping ends and uses the narrowest possible installation space. In the stretch rolling method, a workpiece is successively fed to at least two passes of a stretch rolling unit of a gripping device, wherein the vvorkpiece is rotated by 180° about an axis of rotation lying perpendicular to the main direction of extent of the workpiece between the first pass of the two passes and the second pass of the two passes.

Abstract: An insulating die plate includes two parallel end plates and an insulating layer arranged therebetween which includes ceramic insulating bodies. An insulating body plane parallel to the end plates is defined for the insulating layer. Intermediate spaces are arranged on the insulating body plane between the insulating bodies. A total insulating layer area includes at least surface insulating body portions and surface intermediate space portions. In each section through the insulating bodies parallel to the insulating body plane, an insulating body surface portion in the total insulating layer area is at least 50%, the insulating bodies are symmetrically formed, with the top side equal to the bottom side of the insulating body and each insulating body designed as a plate having a height and a maximum width at least 2.5 times wider than the height of the insulating body; and/or the insulating bodies are anisotropically shaped.
