  • Method of determining a modulus of elasticity of a moving web material
    Patent number: 6993964
    Abstract: A method of dynamically determining a modulus of elasticity of a moving web material using web tensions and web velocities. The tension and velocity of a moving web are determined in a first span. The tension and velocity of the moving web are also determined for the moving web in a second span. A value analogous to the modulus of elasticity of the moving web may then be determined according to the tension and velocity values for the moving web in the two spans.

  • Method of controlling tension in a moving web material
    Patent number: 6991144
    Abstract: A method of dynamically controlling the tension of a moving web material. A web material is transported with an apparatus. A modulus-of-elasticity-analog value is determined for the web material. The modulus-of-elasticity-analog value is used to adjust an instantaneous gain of the web control system. The instantaneous gain is used in the control calculation of the control system. The control calculation is used to control the speed of a web handling drive. Controlling the speed of at least one appropriate web handling drive controls the tension of the web.
