  • Patent number: 7685693
    Abstract: The disclosure relates to a method for forming a die having an applicator slot for translating an applicator liquid through the die. The slot is in fluid communication with a die cavity. An expansible chamber device is disposed within the die cavity and changes volume in response to changes in fluid pressure within the expansible chamber device, which may be regulated by a means for controlling the volume of the expansible chamber device. In some embodiments, the die has a single rectangular applicator slot, and the expansible chamber device is an expandable cylindrical tube disposed within the die cavity. In other embodiments, the fluid within the expansible chamber device may be selected to be a compressible gas. In further embodiments, the fluid within the expansible chamber device may be selected to be an incompressible liquid.

  • Patent number: 7621737
    Abstract: A die assembly includes a die housing having a multiplicity of inner wall sections defining a die cavity, an inlet passageway passing through the die housing in fluid communication with the die cavity, and an outlet passageway passing through the die housing in fluid communication with the die cavity at a position distal from the inlet passageway. The die assembly also includes an insert removably received in the die cavity. The insert includes a body portion having a multiplicity of outer wall sections, and at least one flow channel is formed between at least one inner wall section of the die housing and each opposite outer wall section of the body portion of the insert; fluid communicates between the external supply and each of the flow channels and the outlet passageway. Also provided is a die insert and a method of purging gas from a die having an insert.

  • Patent number: 7524377
    Abstract: The disclosure relates to an apparatus including a die having at least one applicator slot for translating an applicator liquid through the die. The slot is in flow communication with a die cavity. An expansible chamber device is disposed within the die cavity and changes volume in response to changes in fluid pressure within the expansible chamber device, which may be regulated by a means for controlling the volume of the expansible chamber device. The applicator liquid is translated through the die and delivered from the applicator slot at intervals corresponding to actuation of the expansible chamber device. In some embodiments, the die has a single rectangular applicator slot, and the expansible chamber device is an expandable cylindrical tube disposed within the die cavity. In other embodiments, the fluid within the expansible chamber device is an incompressible liquid.

  • Patent number: 6231671
    Abstract: An adjustable mounting system for premetered contact coating dies includes a base and a die-receiving portion movably connected to the base. During coating, the die can float a distance from the surface being coated based on the balance of forces between the die and the coated surface. This creates a variable separation gap and allows automatic self-compensating for variations in web or fluid properties. This, in turn, optimizes the coating characteristics. The mounting system can also include an enclosure for protecting its components.
