Patent ID: 8475875

Claim:
A method for encapsulating a web with an encapsulation material using an encapsulating system having at least one coating blade configured to encourage the encapsulation material to encapsulate the web when the web passes the blade, the method comprising: determining initial material properties of the web; determining a process configuration using a force model of the encapsulating system, wherein the force model is applied based on the initial properties of the web; and encapsulating the web using the determined process configuration, wherein the process configuration comprises one or more of a first entrance angle of a first blade, a first exit angle of the first blade, a first radius of the first blade, a second entrance angle of a second blade, a second exit angle of the second blade, a second radius of the second blade, and tension of the web and wherein the force model comprises: F N ⁢ ⁢ 2 F N ⁢ ⁢ 1 = Cos ⁢ ⁢ θ i ⁢ ⁢ 2 Cos ⁢ ⁢ θ i ⁢ ⁢ 1 ⁡ ( 1 - Cos ⁢ ⁢ θ e ⁢ ⁢ 1 ⁢ μ ) ⁢ ( 1 - Cos ⁢ ⁢ θ i ⁢ ⁢ 2 ⁢ μ ) wherein F N2 is a force normal to the web at the second blade, F N1 is a force normal to the web at the first blade, θ i1 is the first entrance angle, θ e1 is the first exit angle, θ i2 is the second entrance angle, θ e2 is the second exit angle, and p is a coefficient of friction between the web and the blades.
