  • Publication number: 20010021442
    Abstract: On a support material for photographic and non-photographic imaging processes with a raw paper and a thermoplastic layer arranged on the front side, the thermoplastic layer features at least one polyolefin layer arranged on the raw paper, and contains at least one polyethylene layer arranged over the polyolefin layer and at least one of the layers contains a polyethylene obtained by means of metallocene catalysts.

  • Patent number: 6120278
    Abstract: A device for laying a molten film 3 emerging from a slot die 2 onto a rotating take-off chill roll 1 has at least one electrode which is arranged parallel to and at a short distance from the surface of the take-off roll 1 and to which a high voltage in the range from 4 to 12 kV is applied. This electrode is, for example, a metal strip 5 which has a tapering sharp edge 6 that is oriented toward the surface of the take-off roll 1. In addition to this metal strip 5, a second electrode 27 is arranged at a distance from the surface of the take-off roll. This second electrode is a metal strip without a strip edge and has applied to it a voltage of a magnitude that is equal to or different from that of the metal strip 5. As a result, electric fields are formed in addition to the electric field from the one metal strip electrode 5.

  • Patent number: 5975873
    Abstract: A device for laying a film 3 emerging from a slot die 2 onto a take-off roll 1 has at least one electrode that is arranged parallel to and at a short distance from the surface of the take-off roll 1 and to which electric voltage in the range from 4 to 12 kV is applied. This electrode is, for example, a metal strip 4, which has a tapering strip edge 6 this is directed toward the surface of the take-off roll 1. In addition to this metal strip 4, one or a plurality of electrodes 5, 8 and 16 are arranged at a distance from the surface of the take-off roll. These additional electrodes have applied to them an electric voltage whose magnitude is the same as or different from that applied to the metal strip 4. As a result, additive electric fields to the electric field of the one metal-strip electrode are formed.
