Slitter rewinders are machines that cut parent or master rolls of material to a smaller width. These machines are used in the packaging industry, and they can be found in many factories, warehouses and distribution centres. If you’re looking at different types of machinery to purchase for your company, you may be wondering what exactly slitter machines do and how you can make the most out of them. In this blog, we look at everything that has to do with slitting machinery, including what it does, how it works, and what it’s used for, including some examples of ASHE’s slitter rewinders.
What is a slitter rewinder?
A slitter rewinder is a machine that is used to convert or slit many different materials so that they can be cut down into narrower rolls. Master rolls are often made to be as large as possible to be cost-effective, so the slitter rewinder helps convert these large rolls into smaller ones.
A slitter rewinder may look like a simple machine, but it plays an important role in the production process of many industries. The rolls of material that come off the slitter are wound onto a take-up reel. They can then be wound to the same diameter/length or reduced in size depending on what kind of industry ordered them and what they plan on doing with them. Slitter rewinders are available in a large variety of configurations to suit any industry wanting specific materials.
How a slitter rewinder works
The slitting method is the process of cutting a length of material into strips. A slitter rewinder has three main components: the unwind, the slitting method, and the rewind. The machine starts when a master roll of material at a given width is loaded into the unwind. As the material is being fed out of the unwind, the slitter component then begins to cut the material into smaller widths following whichever setting you initially programmed the machine to. After slitting the material, the strips then get rewound onto a different core that’s the same width.
What slitter rewinders are used for
Slitter rewinders are used to cut and wind rolls of materials into smaller rolls. Slitters are especially ideal for manufacturers of papers, tapes, films, thin plastics, and foils to easily adjust the dimensions of their products to select a width with uniformity and accuracy.
The slitter rewinder machine is designed in such a way that it can cut the original roll into multiple strips and then wind them back together again on a new roll. This process helps reduce manufacturing costs by reducing waste material that would otherwise be discarded if not used in production processes.
The dynamic blade spacing in most slitter rewinders means they can suit almost any requirement you have when it comes to cutting your material precisely. Many models come with different blade styles available so that you can choose one that best suits your needs for each type of material being used. The various blade styles available help to cut each material exactly how it needs to be cut with no mess and no waste while also reducing production time and cost.
