Label production requires more than good printing. The final label needs clean edges, accurate shapes, consistent dimensions, and reliable finishing. This is where an intermittent die cutting machine plays an important role.
An intermittent die cutting machine controls the movement of label material and performs cutting according to the required repeat length. It can handle printed and plain label applications and helps manufacturers produce consistent labels for different production requirements.
For businesses looking to improve label converting efficiency, understanding how intermittent die cutting works can help them select the right equipment and configuration.
What Is an Intermittent Die Cutting Machine?
An intermittent die cutting machine is a label converting machine that cuts printed or unprinted label material into specific shapes and sizes. Unlike continuous cutting, the machine controls the material feed and cutting action according to the selected repeat length.
The RK Intermittent Half-Full Cut machine supports a die-cutting repeat length from 25 mm to 250 mm and is available in 320 mm and 450 mm paper widths. It runs at 100 to 150 strokes per minute, depending on repeat length, and supports both half cutting and full cutting.
One of the important features of this machine is its common magnetic cylinder (120 or 150 teeth). With one magnetic cylinder, customers can run different repeat lengths from 25 mm to 250 mm without requiring a new cylinder for every label size. This gives label manufacturers greater flexibility when handling different jobs.
How Does an Intermittent Die Cutting Machine Work?
The basic process follows several controlled stages.
1. Material Unwinding
The label roll enters the machine through the unwinding unit. Controlled tension helps keep the web stable as it moves through the converting process.
The RK system uses a 3-inch airshaft and supports a maximum unwind roll diameter of 550 mm.
2. Web Guiding and Servo Feeding
The machine guides the label material through the cutting section. Electronic web guiding helps maintain correct material movement and alignment.
The RK Intermittent Half-Full Cut uses a Schneider servo control system. The paper-pulling system also works through a servo motor, which provides controlled and accurate material feeding during the cutting process.
3. Registration and Re-Pass Scanning
Printed labels need accurate registration between the artwork and the cutting position. A re-pass scanner can detect the print mark and help align the cutting process with the printed design.
This feature becomes useful when converting pre-printed label stock where accurate cutting position is important.
4. Die Cutting
The die-cutting module shapes the label according to the selected die and repeat length.
The machine supports both half cutting and full cutting.
Half cut (kiss cut) cuts the label and leaves the liner. Full cut cuts through the label and the liner, and gives separate pieces like tags.
The common magnetic cylinder (120 or 150 teeth) allows customers to work with repeat lengths from 25 mm to 250 mm using one magnetic cylinder. This reduces the need to purchase a separate cylinder for every label size.
5. Waste Matrix Rewinding
After die cutting, unwanted matrix material can be removed from the label web. An online waste matrix rewinding system collects this waste and helps maintain a cleaner converting process.
6. Rewinding and Collection
The finished labels move toward the rewinding or collection section. Automatic rewinding helps prepare the finished material for the next production or packaging stage.
Why Does Intermittent Die Cutting Matter for Label Production?
An intermittent die cutting machine can help manufacturers improve several parts of their workflow.
Better Cutting Accuracy
Accurate feeding, registration, and die positioning help create consistent label shapes. This matters when customers require precise branding, product information, and packaging presentation.
Flexible Label Production
Different products often require different label sizes and shapes. A machine with an adjustable repeat range can support multiple label formats without requiring a completely different production system.
The common magnetic cylinder (120 or 150 teeth) adds further flexibility because the same cylinder can support repeat lengths from 25 mm to 250 mm.
Half and Full Cutting Options
The machine can handle different finishing requirements through half and full cutting.
Half cut keeps the label attached to the liner, while full cut goes through both the label and liner to create separate pieces such as tags.
Servo-Based Production Control
The Schneider servo control system and servo-driven paper pulling system provide controlled web movement during the production process.
Digital controls also help operators manage machine settings and production parameters.
Automatic Die Cutting Machine vs Manual Die Cutting Machine
Businesses often compare automatic die cutting systems with manual die cutting machines.
A manual machine may suit small operations, basic jobs, or businesses with limited production requirements. However, operators need to manage more production steps manually.
An automatic system can control feeding, cutting, registration, and rewinding with less manual intervention. This can make automation useful for businesses handling repeat orders, larger production volumes, and tighter production schedules.
The right configuration depends on label volume, material, required accuracy, available workforce, budget, and production requirements.
What Applications Use Intermittent Die Cutting?
Intermittent die cutting can support a wide range of self-adhesive and printed label applications.
Common applications include:
- Pharmaceutical labels
- Food and beverage labels
- Cosmetic labels
- Industrial labels
- Product stickers
- Self-adhesive labels
- Paper labels
- Film-based labels
- Tags and other die-cut products
The machine can process materials such as paper, PVC, BOPP, PET, and self-adhesive label stock, depending on the selected configuration.
How to Choose an Intermittent Die Cutting Machine
Before purchasing a machine, evaluate:
- Maximum web width
- Minimum and maximum repeat length
- Required production speed
- Half and full cutting capability
- Magnetic cylinder system
- Print registration system
- Servo control
- Paper pulling system
- Waste matrix handling
- Rewinding capacity
- Supported label materials
- Operator controls
- Service and maintenance support
Do not choose a machine based only on maximum speed. Match the machine configuration with your actual label sizes, substrates, production volume, and finishing requirements.
Conclusion
An intermittent die cutting machine connects printing and finishing by converting printed label webs into accurate and usable label shapes. Controlled feeding, registration, servo-based paper pulling, die cutting, and rewinding can help label manufacturers maintain consistent production.
The common magnetic cylinder (120 or 150 teeth) is also an important feature for businesses producing different label sizes. With one magnetic cylinder, the machine can support repeat lengths from 25 mm to 250 mm, reducing the need for a new cylinder for every label size.
For businesses that need flexible label production, half cutting, full cutting, and different repeat lengths, an intermittent die cutting machine can provide a practical solution for modern label converting requirements.
