The recommended taper program you mentioned in your new winding book Fig 1.6, is very effective. Wow, after almost 5 years, telescoping is now gone. The book he is referring to is Winding: Machines, Mechanics and Measurements, ed.
It is grateful to see people break away from the largely unhelpful discussion of the constant tension or constant torque or other ‘magic’ curves and start letting the wound roll tell us how to program the tension. I wish taper had never been invented because we are saddled with a confusion brought on by a strategy that was easy to program, but very non-intuitive and, more importantly, not as effective for solving the most common types of telescoping, Type 1A (core supported winding) and Type 1B (unwinding).
