Rubber band Rubber band A rubber band (also known as an elastic band, gum band or lacky band) is a loop of rubber, usually ring shaped, and commonly used to hold multiple objects together. 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
Rubber band gun rifles, and Tommy guns. The repeater RBG is usually made of wood (although many Lego-based designs have been produced), and has a plastic firing mechanism, consisting of a toothed wheel onto which the bands are hooked, and a sprung trigger or escapement that releases the wheel by one notch, releasing a rubber band every time the trigger is pulled. In Lego designs, a gear is commonly used in place of the toothed wheel, and due to how fine the teeth on the gear are, the escapement allows a rotation of more than one tooth, requiring rubber bands to be loaded
