The aim of the invention is to improve devices (3) for transporting material webs (1) and for fixing said webs (1) on a counter bearing (4). Said devices (3) have the following characteristics: at least one transport roller (2, 2a, 2b) for transporting the material webs (1) and means for applying an electrostatic charge (q) to at least parts (8) of the material web (1), wherein the electrostatic forces of said charge (q) aid in the fixing of said parts on a counter bearing. The novelty and inventive step of the invention is that at least one transport roller (2, 2a, 2b) comprises means for applying an electrostatic charge (q) to at least parts (8) of the material web (1). The invention also claims a method for operating a device of this type.
