What Is a Slitting Machine?

Reading Time: 5 mins

Slitting machines, also known as slitter rewinders, are used in the converting industry to cut large rolls of material into narrower rolls of material. In this article, we will look at what a slitting machine is, how it works and outline the various types of slitting machines on the market today.

What is a slitting machine?

A slitting machine, also known as a slitter or a slitter rewinder, is an important piece of machinery that the converting industry uses to process various materials. The main purpose of a slitting machine is to slit these materials into smaller rolls for later use.

There are three main components to a slitting machine: the unwind, the rewind and the slitter itself. A large roll of material, such as film, is fed through the unwind. Once the roll of material is unwound, it is cut by the slitter into specific widths before being rewound again with a narrower width.

There are many everyday examples that showcase the work of a slitting machine. For example, receipts from retail stores originate from a much larger, master roll before going through a slitting machine. The final receipt you receive after shopping has been cut into a smaller roll from the master roll by a slitting machine.

Types of slitting machine

There are many different types of slitting machines that offer specific features and functions. Finding the right slitting machine for you will largely depend on your budget and the materials being processed.
