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, by Stephen Perry. 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 across the width of the tube into little bands. Which is then shipped off. While other rubber products may use synthetic rubber , most rubber bands are primarily manufactured using natural rubber because of its superior elasticity. Natural rubber originates from the latex of the rubber tree , which is acquired by tapping into the bark layers of the rubber tree.
