Common Types of Slitter Machine

There are two distinct types of slitting machines: roll slitters and slitter rewinders. Both are commonly referred to as slitting machines. Yet both have distinct differences.

Roll Slitters

Roll Slitters use a large circular blade or fixed band blade to cut all the way through a roll of material. This machine cuts down through the core the material was wound on. The core of most master rolls is a 3″ (7.62cm) ID paper core. The master roll does not need to be unwound. You can skip the time-consuming process of aligning slitting blades and empty cores.

Slitter Rewinders

Slitter Rewinders slit the master roll into any desired width rolls. They first unwind the master roll then pass the entire web through a series of slitters. Afterward, it rewinds each section onto a new core. Slitter rewinders have an unwind for holding the master roll. They have a multi-blade slitting station with adjustable slitting heads. This helps cut the wide material into the required widths. They also include single or duplex rewind shafts. These shafts are for holding the empty cores to rewind the slit material.

Application of Slitter Machine

Paper and Printing Industry

Slitter machines are extensively used to slit large paper rolls into narrower widths, facilitating the production of different paper products such as newspapers, magazines, and packaging materials.

Converting Industry

Slitting machines play a key role in the converting industry, where materials like laminates, tapes, and adhesives are processed into smaller rolls with specific widths for further use in manufacturing.

Working Principle of the Slitter Machine

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's settings. After the material is slit, the strips are then rewound onto a corresponding core of the same width.

Maintenance Tips for Slitter Machine

1.
The machine should be cleaned and maintained with oil diligently.

2.
Every day after work, let out the water of the compressor, and the next day close the valve of the compressor.

3.
Oil the machine regularly every month, and clean the dust of electrical appliances.

4.
Remember, when cleaning and dusting, the machine must be disconnected from the power supply to ensure that there is no moisture in the air emitted from the air compressor before using it.

Ultimate FAQ Guide to Powder Packing Machines

Q: What is a slitter machine used for?

A: A slitter machine (commonly referred to as a slitter rewinder) is a special type of equipment used to convert/slit many different materials so they can be cut down into narrower rolls. Master rolls are often made to be as large as possible in order to be cost-effective.

Q: What is the function of a slitter machine?

A: The mechanism used for the slitting process is often referred to as a slitter, a slitting machine or a slitter rewinder. To put things simply, the main role of a slitting machine is to convert (slit) papers, film and foil materials so that large rolls of these materials can be cut into narrower rolls.

Q: What are the different types of slitter machines?

A: There are two distinct types of slitting machines: roll slitters and slitter rewinders. Both are commonly referred to as slitting machines.

Q: What is the difference between slitting and cutting?

A: - Cutting makes flat sheets or specific-sized pieces from materials.
- Slitting is dividing a material into narrow strips with parallel cuts along its length.

Q: What is the difference between shearing and slitting?

A: Cutting mesh or cloth is referred to as slitting, shearing, or both. Slitting wire mesh is cutting it from a larger width roll to smaller specified widths. Shearing wire mesh is cutting across from the chute direction to 'cut to size' each piece.

Q: What is the maintenance of a slitter machine?

A: Dust, debris, and contaminants can accumulate in various parts of the machine, such as the rollers, blades, and bearings, and cause damage or wear. Regular cleaning with a soft brush, vacuum, or compressed air can help remove these particles.

Q: In which industries are slitter machines commonly used?

A: Slitting machines are widely used in industries such as paper and printing, film manufacturing, textiles, and metal processing.

Q: Can slitter machine handle both continuous and intermittent cutting operations?

A: Yes, slitting machines can be configured for both continuous and intermittent cutting, depending on the application.

Q: What types of blades are commonly used in slitter machine, and how are they maintained?

A: Circular, razor, or crush-cut blades are common. Regular inspections and sharpening or replacement are essential for maintenance.

Q: How can slitting defects be identified and addressed during operation?

A: Defects can be identified through sensor feedback, visual inspections, and monitoring. Addressing issues may involve adjusting blade settings or material tension.

Q: What is the minimum slit width?

A: The general rule is that if the slit widths are greater than 1” (25mm), a center-wind slitter rewinder is recommended. If the slit widths are less than 1”, a center-surface slitter rewinder is a better fit for the application.

Q: How many types of slitting are there?

A: There are three basic types of slitting: razor slitting, shear slitting, and score slitting (also known as crush slitting). Each type is distinguishable by the type of blade, knife, or device used to make the cut. Deciding which system is best depends largely on the type of material being cut.

Q: What is the maximum speed of a slitter machine?

A: The max slitting speed can be 250m/min, single layer slitting speed can be 150m/min.

Q: What are the benefits of slitter rewinder machines?

A: Usually 180-450g/m2.

Q: What affects the slitting process?

A: The most important parameters are the horizontal and vertical clearances, the clamping of the sheet, rake angle or slitter diameter, the cutting speed and the sharpness of the knives. Due to wear, sharp knives will become blunt, leading to poor results, and particularly larger burrs.

Q: Are the requirements for the use of slitting machine equipment high?

A: Slitting machine equipment for product requirements, mainly depends on the user requirements, if the user's product requirements are high, then correspondingly, the requirements of the slitting machine equipment will certainly be higher, and vice versa. So, on this issue, it is not easy to answer. It can only be said that if the slitting machine has a centering system and tension structure, then the performance of the equipment is very good.

Q: Do I need to check blade pressure?

A: Sometimes you may have everything in-line and operating smoothly but seeing that your cuts are fraying or your blades are simply not cutting. in this case, check to see that there is enough air pressure applied to the blades. Not enough pressure on the blades can create a less than satisfactory cut but on the flip side, too much pressure can make the bearings seize up, begin to wear down the blades, and/or begin to scratch the surface of the anvil shaft. It is essential to find the least possible blade pressure that provides a satisfactory cut in order to prevent wear on your anvil shafts, blades, or blade holders.
