FIELD: physics.
SUBSTANCE: invention may be used for removing the static electricity during polymer processing. The device contains at least one attachment with a shell limiting a supersonic nozzle, a corona discharge needle, and an electric circuit connected to the corona discharge needle. The latter is a surgical needle made of chromium steel, tip (38) of which has a diameter less than 30 micrometres.
EFFECT: expansion of functionality.
