  • Process and apparatus for the surface treatment of sheet-like structures by electric corona discharge
    Patent number: 5135724
    Abstract: The process of the present invention is for the surface treatment on both sides of a substrate by means of electric corona discharge, while simultaneously treating both surfaces of the substrate with a carrier gas/aerosol mixture introduced into the corona discharge zone. The arrangement for carrying out this process comprises a corona discharge device, consisting of a generator, high voltage electrodes, to which alternating current is applied by the generator, as well as grounded counter electrodes, a device for the atomization of liquid into a suspendable aerosol, which is connected via a transport line for the aerosol to the corona discharge device, and a blower, which is connected to the atomizer device and conveys the carrier gas/aerosol mixture to the corona discharge device. The electrodes and counter electrodes together form a gap for the substrate to be treated.
    Type: Grant

  • Process for the production of biaxially stretched and embossed film composed of vinyl chloride polymers
    Patent number: 4379774
    Abstract: A process is described for the production of biaxially stretched and embossed polyvinyl chloride film, in which a polyvinyl chloride film is first stretched biaxially at specific stretching ratios and, immediately after being stretched, is embossed under specific conditions. The film produced by this process is employed with particular advantage as base film for adhesive tapes.
