- the volatile components can be easily removed.
- the annealing is advantageously carried out in the absence of oxygen, for example in one closed reactor, under inert gas or in vacuum. This will cause oxidation of the Avoided carbon fibers.
- the starting material can either be heated over its entire length or in sections. It has proven to be favorable to use the starting material in some areas over its length to be heated continuously, the respectively heated length range on the Thorn is wound up. The winding of the band-shaped starting material turns out particularly easy if the mandrel rotates around its longitudinal axis.
- the mandrel can also reach a temperature over its entire length or in sections be heated above the softening temperature of the investment.

- the fact that the heater on the Starting material acts in the area of the surface of the mandrel, the starting material each softened so far in the length ranges fed to the mandrel that it was plastic is deformable and can be wound spirally on the surface of the mandrel.
- the Transfer of heat from the heater to the starting material can be by contact, Radiation, flow or convection take place.
- the heating element can be turned on immediately act on the starting material or indirectly by interposing a transmission medium. It is only essential that the heating device on the starting material in the area acts on the surface of the mandrel.
- a device in which the mandrel rotates about its longitudinal axis has proven to be favorable and in which the heating device is movable relative to the mandrel.
- the heating device and the feed device can be locally fixed, in the latter In this case, the heating device and feed device can be moved along the longitudinal axis of the mandrel educated. Due to the relative displaceability of mandrel and heating device, a targeted, localized heating of the starting material is achieved.
- Heating the starting material with a is particularly easy and precise Embodiment of the device according to the invention, in which the heating device by means of a is parallel to the longitudinal axis of the mandrel linear guide.
- the feed device is advantageously provided with a first drive by means of which it is movable in the direction parallel to the longitudinal axis of the mandrel, with the displacement of the heating device a second drive is provided, which is electrically or mechanically connected to the first drive is coupled.
