Hymen Lipman, an American inventor, received the first patent for attaching an eraser to the end of a pencil in 1858. However, this design was later revised by Hyman Lipman and Joseph Reckendorfer in 1875, leading to a legal dispute over the patent rights, which ultimately established the eraser-tipped pencil we use today.
If the pencil has writng running up the side, put thepencil on its side so the writing is the correct way up, the bottom of the pencil (where you should start sharpening it) is where the writing starts and the top is where it ends. If there is a rubber at one end that's the top. if the pencil has no markings then whatever end you don't sharpen will be the top.
First, they get some wood, sharpen it into a 3D hexagon, make a circular hole through the middle, then put lead in the hole. They then put it on a conveyor belt, and has another super-speedy conveyor belt sharpen one end of the pencil. Then, they add some detail to the pencil. And the pencil is finished :D Optionally, they can also sometimes add a rubber to the other end of the pencil
The metal band that holds the rubber onto the pencil is called a ferrule. It is typically made of aluminum or other metals and is crimped onto the end of the pencil to secure the eraser in place.
An eraser is typically found at the end of a pencil, used for removing pencil marks.
Rubber is able to erase pencil marks because it has a sticky surface that adheres to graphite particles on the paper. As the rubber is rubbed against the paper, it picks up and removes the graphite particles, effectively erasing the pencil marks.
The first person to put rubber on a pencil was Harret Tubbmien.

A pencil rubber otherwise known as an eraser is used to rub out pencil marks on paper

Rubber has a high co-efficient of friction.
at first the rubber is made to erase the pencil mark.
Take two erasers a rubber band and a pencil. Then aline the the rubber band with the ends of the pen. Then put our erasers on the ends to hold the band in place.
rubber
Yes, we can erase pencil marks with rubber because erasers are made out of rubber
a pencil is 7 1/4 inches long with out a rubber on it
