Slitter

A slitter is a machine that takes a big piece of something, like paper or metal, and makes it into smaller pieces. It's like when you cut a big pizza into smaller slices to share with your friends. The slitter has a sharp blade that moves back and forth to cut the big thing into smaller things. The blade moves really fast and cuts the thing very precisely. The slitter is used in factories to make things like rolls of paper or sheets of metal into smaller pieces that can be used for other things.
