Abstract
The description refers to a flexible heating core (1) for the performance of a process by which the amount of heat required for deformation is applied from the inside to the workpiece to be deformed. The heating core (1) is designed in such a way that a heating conductor coil (3) is located in an insulation sleeve (4), that it has a radially expandable jacket (2), and that the jacket (2) and the insulation sleeve (4) together form a chamber (6) to receive liquid media.
