What does a slitter do?
First, let’s start with a basic definition: A slitter produces narrow widths from wider sheet by means of rotary knives. This process is used to make edges straight and can also be used on both ferrous and nonferrous materials.
What is slitter process?
Coil Slitting is the process of taking a wider master coil and slitting (cutting) it into a series of narrower coils by running the material through a set of rotary slitting knives. Each smaller coil is called a mult. Mults can be customized to your specific width and/or weight and packaged accordingly.
What is slitting in hotel industry?
Roll slitting is a shearing operation that cuts a large roll of material into narrower rolls. There are two types of slitting: log slitting and rewind slitting. In log slitting the roll of material is treated as a whole (the ‘log’) and one or more slices are taken from it without an unrolling/re-reeling process.
What is slitter rewinder machine?
Slitter rewinders are used to roll thin, flexible, non-woven materials, of which paper is a popular, versatile, and prototypical representative, which is why we use it as an example here.
What is a slitter knife?
Circular slitter blades or circular slitting knives are type of blades with sharp cutting edges. They usually have low cutting angles and no teeth. As the name suggests, circular slitter blades are mostly used for slitting type cutting operations.
How does steel slitter work?
The coil slitting process involves large coils of metal are cut using sharp rotary blades. Straight lines are cut lengthwise into the large coil, the resulting strips of metal are narrower in width. As the coil runs through the slitter, two circular blades (one on top and the other on the bottom) make the cuts.
Why is slitting done?
Slitting is a common practice in the converting industry and is used to produce material substrates for a variety of different markets including packaging, food and beverage, pharmaceuticals, fashion, and more.
What is a slitter line?
A slitting line works by cutting a large roll of metal into multiple, narrower rolls. It’s a continuous production process that is very precise. In fact, it’s one of the most precise ways to cut metal compared to other processes. ALCOS ensures that your metal will be cut to your specifications every single time.
What is a slitter machine operator?
What does a Slitter Operator do? “Slice ’em up” is the Slitter Operator’s job in the process of manufacturing items that come on a roll. Aluminum foil, cash register printer paper, and shrink wrap all start out on enormous rolls until the Slitter Operator chops them down to convenient sizes with a slitter machine.
Who is a rewinder?
Definition of rewinder : one that rewinds something: such as. a : an operator of a machine for rewinding yarn, cloth, paper. b [re- + winder]
What are slitter blades?
How do you sharpen slitter knives?
DANGER: Slitter blades are extremely sharp!…Grind with a boron nitride wheel, Norton CB181-TBB or equivalent.
- Sharpen only the top slitter end surface at an angle of 45 degrees.
- Feed 0.02 mm (0.0008″)/stroke.
- Grind the top slitter with a rotational speed of 30-60 rpm against the rotating direction of the wheel.
What is a metal slitter?
Metal slitters take wide coils and cut them down to narrower widths. This process can be done for inventory purposes or when a customer requires a specific width. Sheet metal slitting requires specialized machinery and, when it’s done properly, can make additional processing faster and more precise.
What is metal slitting machine?
Slitting is a metal manufacturing process wherein a coil of material, such as aluminum or steel, is slit into the lengths and widths specified by the end application. As the material runs through the machine, the steel rolls are moved through extremely sharp circular blades, making the cuts.
What is knife clearance?
SLITTING CLEARANCE: Proper knife clearance minimizes burr, increases knife’s life by reducing wear and tear. Italso reduces stress on the machine and improves slit width tolerance. While slitting, knives cut partially through the metal. The material then fractures, the rest of the way.
What is a steel slitter?
Steel slitting is a steel manufacturing process wherein a coil of steel is slit into the lengths and widths specified by the end application. This process requires machinery lines equipped with a decoiler, slitter, and a recoiler — to achieve the end product: slit steel coils, or “mults.”
What are slitted coils?
Coil slitting, or roll slitting, is the process in which a large master coil is uncoiled and sent through a set of two circular wheels, or shears. These shears are set at a predetermined width and cut the coil into a series of narrower rolls.
