Abstract
Systems and methods for dispensing liquid materials as may be used in applications for coating flexible films and the like. Such a film may be coated by dispensing a rheological material onto its surface while drawing the film through a gap between a pair of rollers. The gap defines the thickness of a layer of the material applied to the film and is maintained at a desired width by microwires positioned through the gap. Another film across the gap from that to which the rheological material is applied aids in the coating of the layer and a contact area of the second film may be adjusted relative to the gap, e.g., when changing materials or when the coating film becomes abraded or deformed.
Claims8
A method of coating a film, comprising dispensing a first rheological material onto a surface of a flexible film while drawing the flexible film through a gap between a pair of rollers, said gap defining a thickness of a layer of the first rheological material applied to the flexible film by being positioned after a coating area in which the first rheological material is applied to the flexible film in a direction of flexible film travel, and maintaining said gap at a width by positioning first microwires through the gap as the dispensing of the first rheological material takes place.
