  • Web feeder with controlled electrostatic force and method
    Patent number: 5964988
    Abstract: A method and apparatus for applying a uniform electrostatic force to a web moving between a pair of electrodes to create an electron wind that urges the web toward one of the electrodes controls the current forming the electron wind to maintain the current and the wind force substantially constant even though impedance may vary. The method may be used to provide a hard nip, to adjust tension, to spread and/or to smooth a coating, to remove curl, and to cure a coating.
    Type: Grant
    Filed: January 22, 1998
    Date of Patent: October 12, 1999
    Assignee: Avery Dennison Corporation
    Inventors: Joseph A. LaRose, Allen Steven Pucciani
  • Process using electrostatic spraying for coating substrates with release coating compositions, pressure sensitive adhesives, and combinations thereof
    Patent number: 5954907
    Abstract: This invention relates to a process for applying a coating material comprising a release coating composition or a pressure sensitive adhesive composition to a substrate, the process comprising: (A) atomizing and electrically charging said coating material; and (B) spraying the atomized and charged coating material from step (A) on to a substrate which overlies a grounded support structure. In one embodiment, the coating material sprayed during step (B) is a release coating composition, said process further comprising the additional steps of: (C) curing said release coating composition; (D) atomizing and electrically charging a pressure sensitive adhesive composition; (E) spraying the pressure sensitive adhesive composition from step (D) on to said substrate over the cured release coating composition from step (C); and (F) placing another substrate over the sprayed pressure sensitive adhesive composition from step (E).
