| The first practical use of a conveyor belt,used in coal mining,came in 1892 with an actual rotating belt,to conveyor the coal to the surface,and where the name came from. Today metal cylinders in very tight successions are used to move many heavy thing along a flat path safely. Left tightly packed,the rollers are just flat lines. |
