  • the aim of this measure is the achievement of a Adhesion between these webs of material or between the top and the bottom of the film tube, which prevents the webs are lifted from each other in their transport by their air resistance.
  • This method is advantageously used in all types of devices in which webs or film tubes are transported. Thus, for example, in tubular film extrusion lines, film hoses are transported over longer distances, wherein a lifting of the top side from the underside of the hose is undesirable.
  • the object of the present invention is to propose a device with which the adhesion of the material web on its counter-layer can be brought about even more reliably than before.

  • electrically conductive plastics come into consideration, which usually consist of macromolecules having a plurality of delocalizable electrons. These electrons are often derived from multiple bonds between the atoms of the molecules.
