8 The Cotton Gin: What is it? The cotton gin is a machine used to separate cotton fibers from the seed.
9 How The Cotton Gin Works First, the fibers and seeds of cotton bolls are fed into the cotton gin…Next, while the handle is turned, the cylinder and brushes rotate…Wire teeth pull cotton bolls through narrow wire slots…Seeds too large fall to bottom of the gin…5. Clean cotton fiber is pulled by rotating brushes from wire teeth out of the gin.
