¶ Hex-pent Sphere: Transformation into Geodesic Spiral Tube (2)

Index Entry
"rollers, and this bubble of air is continually rolled into the rod, stretching it into a thin transparent monomer film. The last roll through which the material passes folds together the two surfaces in a long tubular sheet. This tube is, after the last roll, slit open and the whole of it is stretched out into a longwise film and gathered into rolls. This is the way the thin plastic film such as Saran manufactured by Dow is made.
“It would seem then that this particular structure would be essential in accommodating going from a cylinder to a sphere and back to a cylinder again, which would account for how this invisible transformation occurs from a thick mass to a uniform thin film.”
