Abstract
A pinning device for the electrostatic pinning of a film on a chill roll is disclosed having a first coil unit, a second coil unit, a pinning region situated between the coil units, a high-voltage source as well as at least two electrodes. At least the first electrode of at least two electrodes is strip-shaped. The electrodes run from the first coil unit to the second coil unit in the pinning region and high voltage is applied to both electrodes by the high-voltage source.
