Types of Turret Slitter Rewinder

Shear slitting

Shear slitting involves a two-part knife with a male and female end through which the substrate passes and is cut. This process is ideal for fast converting and is perfect for transforming various thin materials with precision.

Razor slitting

Razor slitting uses a razor blade or a series of razor blades mounted onto a machine that slices the material into the desired widths as it passes through. Depending on the placement of the razors, slitters using this method can convert either slowly (top) or quickly (bottom). Of the three types, razor slitting is the least expensive and is best for converting very thin substrates like films.

Score slitting

Score involves a moving substrate passing between a solid rotating anvil and a circular rotating knife or series of blades. This method is the most popular of the three and is ideal for converting various substrates of varying thicknesses and rigidities.

Application of Turret Slitter Rewinder

The slitting rewinding machine was mainly used to convert printed,laminated plastic film rolls into custom width rolls in the flexible packaging industry,such as PET, OPP, CPP, PE, PS, PVC,BOPP,laminated film material,self adhesive label and so on. These plastic film or laminated film rolls are widely used to make various type label or wrapping sugar,salt,tea,wipes,milk powder,medical,food,candy packaging,PVC shrink label film for bottle water label,beverage bottle label,BOPP laminated film roll for food pouch.

Components of Turret Slitter Rewinder

01.

Pay-off or uncoiler reel

This firmly grasps the master coil on the internal diameter utilizing a stretchable mandrel. The coil is fed to the slitter by jogging or rotating the mandrel.

02.

Slitter

This consists of 2 parallel arbors positioned by rotary cutting knives. The knives partially penetrate the coil stock resulting in a fracture or crack on both sides. This is how the material is separated.

03.

A recoiler

The recoiler takes the slit coils at a driven, stretchable mandrel. It is fitted with separator discs.

04.

A tensioning unit

This component is mounted between the subsequent recoiler and the slitter. The unit is required since the master coil is bigger in width or crowned at the middle of the diameter as compared to the edges.

Process of Turret Slitter Rewinder

Material introduction: First, the large roll of material is fed into the feeding section of the slitting rewinding machine. This process can be done manually or automatically. The feeding section typically includes a tension control system to ensure the material maintains proper tension throughout the process.

Cutting: Once the material enters the slitting rewinding machine, it is cut by the cutting device. The cutting device usually consists of a pair of rotating blades that can be adjusted as needed. The design and setup of the cutting device depend on the type and thickness of the material used.

Guiding and positioning: After cutting, the smaller rolls of material are guided and positioned by a guiding system and positioning device. These devices help ensure that the material maintains the correct position and direction during the cutting process.

Rewinding: Once the material is cut and positioned, it is rewound by the rewinding device. The rewinding device typically consists of one or more spools that wind the cut material into smaller rolls. The rewinding device usually features an automatic tension control system to ensure stable tension during the winding process.

Discharge: After rewinding is completed, the smaller rolls of material are discharged from the slitting rewinding machine through the discharge section. The discharge section typically includes a collection device for gathering and stacking the smaller rolls of material.

How to Maintain Turret Slitter Rewinder

This will help to remove any build-up of debris and ensure that all the moving parts are free from obstruction.

Clean the machine regularly

This will help to keep them moving smoothly and prevent any wear and tear.

Lubricate the moving parts

Make sure that they are sharp and in good condition. If they are starting to show signs of wear, then replace them as soon as possible.

Inspect the blades regularly

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.

How to choose Slitter Rewinders

01/

Material compatibility: Different slitter rewinders are designed to handle specific materials such as paper, film, foil, or nonwovens. Ensure the machine you choose is compatible with the materials you typically work with. Consider aspects like width, thickness, tension control, and the ability to handle different material types, including sensitive or delicate ones.

02/

Slitting mechanisms: Evaluate the available slitting mechanisms, such as shear, razor, or crush cut. Each unique mechanism has its own advantages and is suitable for specific applications. Consider the quality of the finished slit edges, the complexity of setup and maintenance, and the flexibility to handle various slitting configurations.

03/

Speed and productivity: Production speed is a crucial factor to meeting demand requirements as efficiently as possible. Be sure to assess the required speed and evaluate the machine's capabilities in terms of maximum web speed, acceleration, deceleration, and overall productivity. Look for features that optimize uptime and minimize downtime, such as automatic roll changes or quick knife adjustments.

04/

Automation and technology: Advancements in automation and technology have greatly improved slitter rewinder operations and productivity. Look for features such as automatic core loading and unloading, web guiding systems, computerized control panels, process recipe creation and selection, data logging, and integration with other equipment. These features can significantly enhance efficiency and reduce operator error.

05/

Operator-friendly design: A well-designed slitter rewinder prioritizes operator safety, ergonomics, and ease of use. Look for features such as intuitive controls, safety mechanisms, easy access for maintenance and blade changes, and ergonomic workstations. Operator-friendly machines not only improve safety, but they also boost productivity by minimizing worker fatigue and reducing setup times.

06/

Cost and return on investment: While price is a significant factor, it should not be the sole determining factor when deciding which slitter rewinder to purchase. Focus instead on the long-term return on investment (ROI) rather than basing your purchase decision on the upfront cost alone. Evaluate the machine's durability, performance, and the potential cost savings it could bring through increased efficiency, reduced waste, and improved quality as a whole.
