Pleated Skin Actuation

Hi I'm trying to actuate the pleated skin shown in this model. I am planning on using servos to move the pleated skin in the form of a sin wave. I have a series of structural columns in the model that would be the base for the servos, but I was wondering what is the correct logic for the grasshopper definition. Im planning on offsetting the points on the uv line and redrawing curves so they can become the "arms" for the servo that actuate the skin. Thanks for your help and let me know if you need some clarification.
