 There's never been a solution to this problem. So I would sit and watch through the glass of these appliances as my sheets would twist and tangle in front of my eyes until I figured out the physics behind why that was happening. And then I taught myself SolidWorks, which is a professional engineering CAD program in order to design a product that would solve this problem at last. I don't have a background in engineering, or manufacturing, or product development. None of it.
