MATERIAL & OUTPUT
Paper Grade and Roll Format Come First.
Kraft, coated and thermal papers have different handling and cutting needs. Review grammage, coating, parent-roll condition and the finished-roll format together.
Coated and Label Papers
Describe the coating or laminate and your edge-quality requirements. Mention dust, coating damage or winding issues seen in the current process.
Thermal and Specialty Papers
Provide coating information, roll length and core size. Small finished-roll applications should also be reviewed through the thermal-paper category.

Parent-roll diameter is the diameter of the incoming roll, not the material working width. Confirm working width, roll weight and operating range for your application.
APPLICATION & PROCESS
Different Paper Grades. Different Edge and Winding Priorities.
Kraft & Packaging Paper
Consider parent-roll weight, dust at the slit edge and the firmness needed for downstream converting. Large roll diameters also affect loading and finished-roll removal.
Coated & Printed Paper
Surface marking, coating condition and edge dust influence the cutting and contact arrangement. Include any printed register or inspection requirement in the brief.
Thermal & Label Papers
Thermal coatings and layered label constructions require material-specific handling. Finished diameter, core and roll length should be defined alongside slit width.
Narrow Rolls & Wide Webs
Minimum slit width changes with machine construction and, on some surface-winding models, working width. Compare the actual configuration rather than applying one minimum across the range.
APPLICATION & PROCESS
What to Check in a Material Trial.
Use a representative web and the intended slit pattern. Review edge condition, lane separation and finished-roll build at an agreed speed. Record the material, setup and results so the trial can be compared with the final supply.
MACHINE FORMATS & CONFIGURATIONS
Match the Winding Format to the Roll.
Horizontal, vertical and centre-surface layouts serve different roll requirements. Compare parent-roll capacity, finished diameter and winding construction before choosing a speed range.
| Model | Winding format | Listed speed | Min. slit | Parent Ø | Finished Ø |
|---|---|---|---|---|---|
| QFJ-A400 | Horizontal · air-shaft rewinding | 400 | 30 | 1,200 | 1,000 |
| QFJ-A500 | Horizontal · differential-shaft rewinding | 500 | 20 | 800 | 600 |
| QFJ-B500 | Vertical · differential-shaft rewinding | 500 | 20 | 700 | 400 |
| QFJ-C400 | Centre-surface contact winding | 400 | 5 / 10 | 1,200 | 600 |
Values describe the configurations shown, rather than guaranteed production performance. Width-dependent slit limits are explained below. Material grade, thickness, slit pattern and final equipment scope determine suitability. Different versions of the same model must be compared using a matching specification.
QFJ-A400 · Horizontal · air-shaft rewinding
A large-roll horizontal layout with separate servo control for each rewind shaft. Chain unloading and independent shaftless loading address roll-handling requirements.
QFJ-A500 · Horizontal · differential-shaft rewinding
Differential rewind shafts and separate servo control provide a configuration to discuss when slit lanes need individual winding accommodation.
QFJ-B500 · Vertical · differential-shaft rewinding
An integrated vertical format for smaller finished-roll diameters. Consider operator access, core preparation and handling alongside available floor space.
QFJ-C400 · Centre-surface contact winding
Separate servo control for the winding shafts. The 1,300 mm configuration lists a 5 mm minimum slit; the 1,800 mm configuration lists 10 mm. A connected-layout version lists an 800 mm parent roll.
CONNECTED ENGINEERING
From Parent Roll to Finished Roll.
Slitting quality depends on how the complete web path works together. Review each stage against your material and output.

BEFORE YOU SPECIFY
Questions Buyers Ask
Which model should I choose for kraft paper?
Start with grammage, parent-roll size and finished-roll format. Compare the listed models, then confirm the complete configuration for your paper.
Can the listed speed be reached with every paper grade?
No. The listed value is a maximum mechanical-speed reference. The paper, slit pattern, roll condition and configuration affect production speed.
Are the unwind and rewind diameters fixed?
The original specifications identify customization for some diameter fields. Confirm the required diameters, load and handling arrangement in the quotation.
What is the difference between gsm and thickness?
Gsm describes paper mass per area. Thickness is a separate measurement. Provide both when available; do not substitute one for the other.
