Abstract
Successive filter rod sections which are produced in a filter rod making machine are caused to pass through a body of ionized air before they leave the machine. This insures that ionized air destroys the electrostatic charges which the non-conductive wrappers and/or fillers of filter rod sections accumulate in the machine upstream of the ionizing station. The conveyor or conveyors which transport the filter rod sections through ionized air are designed to transport the sections sideways. At least one electrode of the ionizing device or devices for air is preferably connected with a source of high-voltage a-c energy.
