  • Through-roll profile unwind control system and method
    Patent number: 7380747
    Abstract: A method of unwinding material in a process system for producing a product includes the steps of loading a roll of material in an unwind system, programming a controller with an unwind equation, the controller in communication with the unwind system, computing a material feed rate based on a predetermined product circumference and an average stretch-to-stop roll profile, and putting a diameter of the roll of material and the material feed rate in the unwind equation of the controller, and unwinding a varying amount of material from the roll of material at a varying unwind speed, the controller being responsive to the unwind equation to vary the unwind speed for forming a plurality of products, each product defining a respective circumference substantially equal to the predetermined product circumference.
