Abstract

Exchangeable containers are movable by a gripping device (26), insulated against earth to the material removal point (1,2), supplied with high voltage from the spraying unit (10), across an insulated stretch (30). The gap is sufficient for ensuring the high voltage insulation of the material removal point (1,2). The containers are movable linearly across the insulated stretch.
