By moulding rubber into an eraser shape? The friction of the rubber onto the paper makes the pencil lines move and removes it that way.

Charles Marie de la Condamine, a French scientist and explorer, was the first European to bring back the natural substance called "India" rubber. He brought a sample to the Institute de France in Paris in 1736.
In 1770, the noted scientist Sir Joseph Priestley recorded the following, "I have seen a substance excellently adapted to the purpose of wiping from paper the mark of black lead pencil." Europeans were rubbing out pencil marks with the small cubes of rubber, the substance that Condamine had brought to Europe from South America. English engineer, Edward Naime is also credited with the creation of the first eraser in 1770. Before rubber, breadcrumbs had been used to erase pencil marks. Naime claims he accidentally picked up a piece of rubber instead of his lump of bread and discovered the possibilities.
In 1839, Charles Goodyear discovered a way to cure rubber and make it a lasting and useable material. He called his process vulcanization, after Vulcan, the Roman god of fire. In 1844, Goodyear patented his process. With the better rubber available, erasers became quite common.
