Paper Slitters and Sheeters
Kraft Paper Slitting Machine-vertical type
The LFQ series vertical slitting machine converts large kraft paper mother rolls into narrower finished rolls in a single pass. Unwinding, slitting and rewinding are integrated, so a paper converter can split wide reels into custom widths without manual handling. This is used by producers who need consistent roll widths for downstream processes like paper cushioning, fanfold paper or pre-opened bags on a roll.
- Converts wide kraft paper reels into multiple narrower rolls in one process, reducing manual handling
- Slitting precision is within ±0.5 mm, ensuring consistent roll widths for automated bagging or wrapping lines
- Adjustable cutting speed from 5 to 180 m/min allows matching output to downstream production rates
- Magnetic powder brake and clutch control maintain stable tension during unwinding and rewinding
- Automatic meter counting stops the machine at the set length, ensuring uniform roll lengths
- Can handle both 3 inch and 6 inch paper cores, matching existing core stock or supplier standards
Problems It Solves
Why Buyers Choose It
- Manual slitting of kraft paper reels is slow and inconsistent, leading to roll width variation
- Buying pre-slitted rolls from third parties adds cost and lead time to production schedules
- Inconsistent roll widths cause jams or misfeeds in downstream automated packaging equipment
- Lack of in-house slitting capacity forces reliance on external suppliers with limited flexibility
- Wide kraft reels are difficult to handle and store without a dedicated slitting line

Process
How The Machine Runs
Step 1Load the mother roll onto the front unwinding shaft with a 3 inch or 6 inch core
Step 2Set the target slitting width and roll length on the control panel
Step 3Start the machine at low speed and adjust the cutting speed to match the material
Step 4Use the photocell edge tracker to keep the web aligned during slitting
Step 5Monitor tension with the magnetic powder brake and clutch
Materials
- Kraft paper reels from 1100 mm to 1600 mm wide
- BOPP, PET, CPP, CPE, PVC, aluminum foil, and other roll materials
- Transparent or color-coded materials with edge or color tracking requirements
Quality Control
- Photocell edge tracking maintains alignment for transparent or color-coded materials
- Magnetic powder brake and clutch ensure consistent tension across the entire roll
- Slitting precision is verified to be within ±0.5 mm across the width of the roll
- Automatic meter counting ensures consistent roll lengths before shipment
- Machines are tested with customer material before delivery to verify performance
Customisation
- Rim charge conveying or rewinding device can be added on order
- Power supply can be built to match the voltage and frequency of the destination country
- Slitting knife configuration can be adjusted for different material types and thicknesses
- Core size can be set to 3 inch or 6 inch based on existing core stock

Comparison
How It Compares
| Buying pre-slitted rolls from a third party | In-house slitting removes supplier margin and delivery delays, but requires investment in equipment and operator training |
|---|---|
| Manual slitting with hand tools | The machine provides consistent width and tension control, reducing waste and operator fatigue |
| Horizontal slitting machines | Vertical design allows easier access to the slitting zone and better material handling for wide rolls |
Use Guide
Running It On Your Floor
- Ensure the unwinding shaft is properly secured with a 3 inch or 6 inch core before loading the mother roll
- Set the slitting width and roll length on the control panel before starting the machine
- Begin at low speed and gradually increase to avoid web misalignment or tension spikes
- Check the first few metres of slitting for edge accuracy and tension stability
- Clean the slitting knives regularly to maintain sharpness and prevent paper dust buildup
