A conveyer belt is a system of pulleys and a loop of material that moves around them, carrying goods smoothly forward. Conveyer belts are used in various kinds of factories to move things automatically.
Conveyer belts are made of rubber, metal, or fabric that's stretched around rotating wheels or pulleys. Boxes or other materials that are placed on one end of the conveyer belt are transported to the other end with no human effort, making them a popular choice in warehouses, manufacturing centers, and other kinds of busy factories. The earliest conveyer belts were used in coal mines in the late 1800s.
