DEVICE AND METHOD FOR TRANSPORTING MATERIAL WEBS AND FOR FIXING SAID WEBS ON A COUNTER BEARING

摘要

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 roll (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), whereby the electrostatic forces of said charge (q) aid in the fixing of said parts on a counter bearing. The invention is characterised in that at least one transport roll (2, 2a, 2b) comprises means for applying an electrostatic charge (q) to at least parts (8) of the material web (1). The invention also relates to a method for operating a device of this type.
