How Do Slitter Rewinders Work?
Slitting machines consist of three main components: the unwind, the slitting method, and the rewind. The process starts when a master roll of material at a given width is loaded into the unwind, allowing you to pay out the material. As the material is fed out of the unwind, the slitter cuts it into smaller widths according to the machine settings. After the material is slit, the strips are then rewound onto a corresponding core of the same width.
A good example of a slitter machine at work is the receipt paper in an ATM machine: The receipt that you receive after using an ATM were originally a part of a master roll. After the slitting process, however, the receipts are divided into smaller rolls of paper, which are then used in the ATM to print out your transaction receipt.
What Materials are Used in Slitter Rewinders?
Slitter rewinders can process a broad variety of both thick and thin materials, including:
- Very high bonding adhesives
- Natural Fabrics
- Plastics (Coated/Metalized)
- Wovens and non-wovens
- Foil (Metals)
- Coated Aramids
- And much more
