You mean 2 3D splines,... either both edges of the ribbon, or one
edge/center and the normal of the ribbon and its width, or similar.

A single 3D spline is not enough for a ribbon.

I would have a look at parametric, probably with precompute, and
functions extracting the component of the splines.

On the u coordinate, the position on the ribbon.
On the v coordinate, the wide of the ribbon.
