Definitions

  • the invention relates to a device and method for transporting material webs and for fixing said webs on a counter bearing.
  • the described devices utilize the electrostatic attractive force which occurs between the start of the material web and the winding core when the start of the material web is charged electrostatically.
  • the charging of the start of the web is carried out by an electrode located in the vicinity of the last transport roller of the winder over which transport roller the material web moves before it reaches the winding core.
  • the still unpublished German patent application having the file number 103 21 599 discloses another winding device in which several material webs or material tubes lying upon each other are provided with an electrostatic charge even before they reach the last transport roller of the winder.
  • the goal of this measure is to bring about an adhesive behavior between these material webs or between the upper side and the lower side of the film tube, which adhesive behavior prevents the material webs from being lifted off from one another by their air resistance during their transportation.
  • This method can be used advantageously in all types of devices in which material webs or film tubes are transported.
  • film tubes are transported over longer distances, for example, in tubular film extrusion units, wherein it is undesirable for the upper side of the tube to get lifted off from the lower side of said tube.
  • material webs are also regarded as a generic term for film tubes and if the term “counter bearing” is used to sum up all types of supports for material webs, such as for example, other film tubes, other material webs and winding cores, then the machines described in the three publications can be characterized as follows:
  • Said machines are devices for transporting material webs and for fixing said webs on a counter bearing, wherein the device has the following characteristics:
  • At least one transport roller comprises means for applying an electrostatic charge to at least parts of the material web.
  • FIG. 1 a A schematic diagram of the winding device of a surface winder
  • FIG. 1 b A schematic diagram of the winding device of the same surface winder as shown in FIG. 1 b [sic; 1 a]
  • FIG. 2 b A schematic diagram of the winding device of the same turret winder as shown in FIG. 1 b [sic; 2 a]
  • FIG. 3 a A sectional view of a transport roller with an example of means for applying a charge to a material web
  • FIG. 4 a A sectional view of a transport roller with another example of means for applying a charge to a material web
  • FIG. 4 b An enlarged section of FIG. 4 a
  • FIG. 1 shows a schematic diagram of the winding device of a surface winder having a contact roller 2 a , which, in the case of the surface winder, is also the last transport roller of the winder that the material web 1 touches before reaching the winding core 4 , which plays the role of the counter bearing here, on which the material web is fixed.
  • the other transport roller 2 which fixes the material web on the contact roller 2 a and which is widely used in the case of surface winders, must also be mentioned here.
  • the electrodes 5 which introduce the charge to the material web, are indicated in the contact roller.
  • the transport direction z of the material web 1 is identical to the direction of rotation z of the roller 2 a .
  • surface winders are a preferred point of use for transport rollers 2 a , which include means for applying a charge to parts of the material web.
  • the winding behavior of turret winders can be improved by the use of such a roller.
  • the material web usually moves over the transport rollers 2 and 2 a onto the old roll 7 .
  • the new winding core 4 is initially backed against the material web 1 .
  • the material web 1 is cut through and the free end (not illustrated) of the material web 1 is wound on the winding core 4 , wherein different methods are known for fixing the free end at first on the winding core 4 .
  • the last transport roller 2 a which the material web 1 touches in the transport direction z, before reaching the new winding core 4 , is equipped with means for applying a charge q to the material web.
  • FIGS. 3 and 3 a show a sectional view of a transport roller 2 b with an example of means for applying a charge q to a material web. These means cover only a certain angle area of the circumferential surface of the roller 2 b , as shown in FIG. 3 [sic; 3 a ].
  • FIG. 3 a shows the structure of the means in detail, is an enlarged section of FIG. 3 [sic; 3 a].
  • the base body 10 of the roller 2 b is often made of metal. It is surrounded by a soft rubber or plastic layer 11 , which is often formed in a foam-like manner and preferably consists of polyurethane. In the region, which serves for applying a charge to the film, this layer is either formed to be thinner than in the remaining circumference of the roller or said layer is omitted altogether in this region. In this region, another insulating layer 12 follows which can be made of Teflon, for example. The purpose of this layer is to insulate the current-carrying metal film 13 reliably against the base body 10 .
  • the current-carrying metal film 13 is followed by the weakly conducting layer 14 which has greater electrical resistance than metals, but lesser than insulators, like for example the Teflon layer.
  • So-called electrically conductive plastics which usually consist of macromolecules having a plurality of delocalizable electrons, are used for preparing such a layer. These electrons often emanate from multiple bonds between the atoms of the molecules.
  • plastics are made more conductive by the addition (doping) of conductive substances such as metals or graphite.
  • the needle-shaped electrodes 15 are located on this weakly conducting layer 14 . These electrodes 15 are also held by the layer 14 , there being no direct electrical contact between the metal film 13 and the electrodes 15 .
  • the needle-shaped electrodes 15 are bordered in their peripheral direction by the circular cylindrical tubes 17 , which are open on their front sides.
  • the tubes 17 for their part, are cast in the plastic layer. However, they can also be removed again so that tubular channels remain in the plastic layer 16 .
  • the plastic layer 16 is flush with the layer 11 and forms with the latter the circumferential surface of the roller 2 b , which is interrupted only by the openings 18 , kept free by the tubes 17 . Due to the openings 18 , the electrodes 15 have free contact with the surrounding area of the roller although their tips do not protrude beyond the periphery of the roller.
