Robots wind what lathes can't
With the mandrel or the eye on a six-axis robot, a part no longer needs a straight axis: elbows, tees and frames become windable, within the robot's reach and away from its singularities. On an elbow, the inside of the bend limits how low the winding angle can go: gentler bends allow lower angles.

An elbow with a bend radius of 1.5 diameters, or 3 diameters: which one lets you wind lower angles?
Three diameters. On the inside of a tight bend, the surface is saddle-shaped, and low-angle fibres slip or lift off. The gentler the bend, the lower the angle you can hold.
