LESSON 6.3 · 1:54 · CHAPTER 6 · THE MACHINE AND THE CELL
Turning around at a pipe end
A pipe has no dome, so the fibre turns around at the end by dwelling or overshooting. A long dwell lays near-hoop wraps on one spot: a thick, wasted end. A short overshoot turns the fibre in less length with less build-up.

A long dwell, or a short overshoot: which wastes more material at the end?
The long dwell. If the carriage carries on a little past the end, slowing down as the mandrel turns, the fibre swings round in a shorter length, with fewer wraps on one spot.

About the numbers
Simulations in this lesson are our own. Where a number rests on an assumption, the video marks it with an asterisk and says where it comes from.
