Types of Slitting Rewinding Machine
 

Duplex slitter rewinder
The Duplex Slitter Rewinder features dual rewind shafts and is characterized by its ability to simultaneously process multiple rolls on two rewind shafts. This rewind method can be further identified as Duplex Center Winding and Duplex Surface Winding.

 

Surface winding slitter rewinder
While the Surface Winding method is applicable to duplex shaft winding, it is primarily utilized for rewinding materials onto a single rewind shaft. This configuration is particularly suitable for handling small rolls with rapid production turns, as well as large-scale rolls like papers and nonwovens . The Surface Winding method offers notable advantages in terms of roll stability and alignment, ensuring high-quality rewound rolls.

 

Turret slitter rewinder
The Turret Slitter Rewinder is renowned for its innovative turret design,enabling seamless and rapid changeover between various slitting modes. A notable characteristic of a slitter equipped with turret winding is its system comprising multiple winding shafts situated on a rotating turret, allowing for uninterrupted operation. While one shaft actively winds the material, the remaining shafts can be prepared for the subsequent roll. This simultaneous operation substantially decreases downtime, enhances productivity, and optimizes the utilization of the slitter.

 

Two drum slitter rewinder
The two-drum slitter rewinder typically refers to a configuration where the slitting and rewinding process is carried out using two driven drums for surface winding. In this setup, the material is fed through the slitting section and then wound onto the two parallel drums, creating a tightly wound roll. The driven drums provide the necessary tension and control to ensure proper winding of the material.

 

Individual arm slitter rewinder
The Individual Arm Slitter Rewinder, also referred to as a Primary Slitter Rewinder, is a specialized machine used for the initial slitting and rewinding of mother rolls. This type of slitter rewinder is commonly employed in the film production industry. One notable feature is individual winders, which are positioned on a linear rail. This arrangement allows for easy adjustment based on the specific slitting specifications required. Each individual winder has its own rewind motor, enabling precise tension control for each rewinding operation. In cases where a full-width winding is necessary, a combination of motors can be utilized to handle the heavy-duty operation.

 

Narrow web slitter rewinder
The narrow web slitter rewinder is a compact and space-efficient machine designed to handle narrow-width materials. One of its standout features is its doctoring capability, allowing for the reprocessing of unqualified rolls and effectively eliminating imperfections in the material. Additionally, narrow web slitter rewinders are user-friendly, thanks to the cantilevered unwind and rewind shafts that enable easy loading and unloading.

 

Spooling slitter rewinder
Spooling Slitter Rewinders are commonly used to handle adhesive or non-adhesive materials with small slitting widths, while requiring long running length accumulation. Typically, these spooling winders have a modular design that allows for future expansion by adding an unlimited number of spooling heads. Each spooling head is equipped with its own drive and tension control, providing the flexibility to modify the spooling geometry based on specific needs, such as traverse, taper, step, and flanged winding.

How to Maintain Slitting Rewinding Machine
 

 

 

Establish a regular maintenance schedule
One of the most important steps in maintaining a slitter rewinder is establishing a regular maintenance schedule. This schedule should include daily, weekly, monthly, and annual tasks, such as cleaning, lubrication, inspection, and calibration. It's important to follow the manufacturer's recommendations for maintenance against the user manual and record all activities in a logbook.

 
 

Keep the machine clean and lubricated
Keeping the slitter rewinder clean and properly lubricated is crucial for its longevity and performance. 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. Lubrication should also be done according to the manufacturer's instructions, using the recommended type and amount of oil or grease.

 
 

Check the tension and alignment of the web
The tension and alignment of the web, or the material being slit and rewound, can affect the quality and consistency of the finished product. Slitter rewinders have various mechanisms for controlling web tension and alignment, such as dancer arms, load cells, and edge guides. It's important to check these mechanisms regularly and adjust them as needed to maintain proper tension and alignment.

 
 

Monitor the blade sharpness and wear
The blades of a slitter rewinder are critical components that determine the quality and precision of the slitting process. Over time, the blades can become dull, chipped, or worn, which can result in poor cuts, ragged edges, or material jams. It's important to monitor the blade sharpness and wear regularly and replace them when necessary. Some slitter rewinders have automatic blade sharpening systems, which can save time and ensure consistent sharpness.

 
 

Diagnose and troubleshoot issues promptly
Despite proper maintenance, slitter rewinders may experience occasional issues, such as material wrinkles, web breaks, or machine malfunctions. It's important to diagnose and troubleshoot these issues promptly to avoid further damage or downtime. Some common troubleshooting steps include checking the web tension, examining the blade sharpness, inspecting the rollers, and analyzing the electrical or mechanical components. If the issue cannot be resolved, it's recommended to consult the manufacturer or a qualified technician.

 

 

Tension Control in Slitter-Rewinders
 
 

Web tension is the force applied to a continuous web of material in the slitting and winding process. Driven rollers can give an operator some control over tension using speed. Undriven rollers can also change the tension because of effects including the drag of bearings and resistance to speed changes. Improper tension can cause many material faults such as telescoping rolls, roll blocking, crushed cores, material wrinkles, web stretching, etc.

 

Most slitting and winding applications include three types of zones: Unwind, slitting, and rewind. A different tension level may be required in each individual zone, and should be monitored and controlled for optimum results.

In the Unwind Zone, the master roll is typically controlled by a brake or motor attached to the shaft or core chuck. The torque applied at the core is transmitted through the radial layers of roll to produce tension at the outside of the roll. Keeping web tension constant is important for the unwind process. A constant shaft torque will create increasing tension as the roll diameter decreases, so torque needs to be varied proportionally based on the variation of roll diameter. Roll inertia is another factor. If the brake or motor is not strong enough for the size of the roll diameter to properly handle the calculated inertial torque during acceleration and deceleration, the roll inertia can push out too much material causing slackness in the web which can contribute to unsuccessful slitting.

 

After the Unwind Zone the web continues to the Slitting Zone. Most of these rollers are typically driven by a motor through a chain or belt drive. Tension control must be maintained to keep a constant tension in the slitting area, especially for some stretchy and thin materials. Web material which is not well-tensioned in the slitter zone will cause a low quality slit edge as the material will not be firm enough for the knife to easily slice through. The material may also wander slightly causing incorrect slitting widths.

 

After the slitting zone, the product (strands) proceed to the Rewind Zone traveling on more driven rollers to their new cores to be rewound. Just like the unwind area, the tension is carried over from the slitter and will have to be tensioned by the torque of the winding shafts. The torque applied to the shaft is shared among the rolls winding on that shaft. If the winding rolls have differences in diameter or length, some rolls may wind tighter than others. In the rewind zone, the tension must decrease as the rolls get larger so as not to crush cores or break the web. Taper Tension is a feature of some automatic tension controllers where the diameter of the rolls are measured via an input device. As roll diameters increase, the rewind motor is made to slow down a certain percentage to correspond to the required output. This results in rolls with natural tension progression that are unlikely to incur defects during handling and storage.

 

While theory can be valuable in establishing the process of a slitting operation, in some unique slitting and winding applications optimal tension levels can only be determined after actually running a test web through the machine to find the best tension setpoint for each respective zone.
