Abstract
A device for coating fiber-based hollow bodies with a barrier layer, including an electrically conductive mold with a first port for receiving the body and including a spray lance with a second port, which spray lance can be introduced into the body and through which a polymer powder can be introduced into the body. A power source can be connected to the first and the second port, as a result of which an electric voltage can be realized between the mold and the spray lance. An electrically conductive and compressible compensation element is arranged on the inner side of the mold.

A device for coating fiber-based hollow bodies with a barrier layer, comprising:
- an electrically conductive mold with a first port for receiving the body,
- a spray lance for dispensing a polymer powder with a second port, which spray lance can be positioned at a distance from the body,
- a power source being connectable to the first and the second port, as a result of which an electric voltage can be realized between the mold and the spray lance, wherein
- an electrically conductive and compressible compensation element is arranged on the inner side of the mold.
