  • Method of controlling coating edge thickness in a web process
    Patent number: 7867562
    Abstract: One method for controlling edge thickness includes applying a coating to a moving substrate, thereby forming a film having a cross direction and a machine direction and one or more edges. The method also includes modifying a thickness of a first portion of the coating along one of the edges of the film, thereby forming a film having a substantially predetermined profile in the cross direction. A method of making a polymeric sheet includes applying a polymer to a moving substrate, thereby forming a sheet having a cross direction and a machine direction. This method further includes removing a first portion of the polymer from a first edge of the sheet, thereby the sheet having a substantially predetermined profile in the cross direction.
