The rubber band was patented in England on March 17, 1845, by Stephen Perry. Most rubber bands are manufactured out of natural rubber or, especially at larger sizes, elastomer, and are sold in a variety of sizes. Rubber bands are made by extruding the rubber into a long tube to provide its general shape, putting the tubes on mandrels, curing the rubber with heat, and then slicing it

A rubber band has three basic dimensions: length, width, and thickness. (See picture.) A rubber band's length is defined as half its circumference. Its thickness is the distance from the inner surface to the outer surface, and its width is the distance from one cut edge to the other. If one imagines a rubber band during manufacture, that is, a long tube of rubber on a mandrel, before it is sliced into rubber bands, the band's
