Rubber Thread: One Long Strand Cut Spirally from Cured Sheet (Gibbons 1934)
The rubber in elastic webbing and braided elastic is not spun: it is cut. A thin cured sheet is wound on a big drum and a small fast circular knife, walked across the drum by a lead screw, cuts it into one long square strand. How fast the knife travels sets the thread's width. This is how Edwin Gibbons described the American practice in 1934.

Cut with the travelling knife
Cut with the travelling knife
Turn the drum very slowly and bring a small, high-speed circular knife against the rubber. A long lead screw carries the knife across the drum face; its speed against the drum sets the width of the cut, and so of the thread.
