Separate Unwind Layout
The unwind section is physically separated from the main converting section. Review the machine drawing and threading route to establish the space between sections, maintenance clearance and the incoming-roll access.
SLITTING & REWINDING · QFJ-AF400
QFJ-AF400 Horizontal Slitter Rewinder
Review a horizontal configuration for larger parent and finished rolls. The AF400 combines air-shaft rewinding and separate servo control with a listed 400 m/min speed, 1,200 mm parent-roll diameter and 1,000 mm finished-roll diameter.
- Listed speed
- 400 m/min
- Minimum slit

Listed configuration values. Production speed and practical slit pattern depend on the material and the agreed machine setup.
Where This Configuration Fits.
Start with AF400 when large finished rolls and a separate unwind section are important to the production layout. Compare roll weight, loading access and the finished-roll removal route alongside working width. A larger roll envelope can reduce the frequency of roll changes, but the complete handling plan still needs to suit the installation.
CONSTRUCTION & CONTROL
Look Inside the Machine Format.
Air-Shaft Rewinding
Air-expanding shafts grip the finished-roll cores, with separate servo control for each winding shaft. Specify core dimensions, roll weight and shaft interfaces together; the diameter values alone do not define the permitted load.
Chain Unloading
Chain unloading is listed for the large-roll configuration. Confirm the unloading arrangement against finished-roll mass, removal height and the transport method used at the next process.
Width and Drive Choices
The range includes 1,300, 1,600 and 1,800 mm unwinding widths. Main and unwind drive ratings change on the widest configuration, so the electrical review should use the selected width version.
MATERIAL & FINISHED ROLL
Define the Web You Need to Convert.
Paper and Packaging Rolls
Provide paper grade, grammage, slit widths and winding firmness. Include dust and edge condition where the finished rolls feed printing, packaging or another converting operation.
Film and Composite Webs
PVC, BOPP, CPP, PET and composite films require review of thickness, stretch and surface contact. Define the construction and finished-roll quality before agreeing the cutting and winding setup.
Aluminium Foil
Identify foil grade, temper, thickness and acceptable edge condition. Review the required cut and roll build on representative material rather than applying paper settings to foil.

Drive powers are individual motor entries, not the total installed electrical load. Confirm voltage, frequency, utilities, roll weight and core interfaces with the proposed supply. Required material thickness and production tolerances are application-specific.
SETUP, OPERATION & ACCEPTANCE
From Parent Roll to the Next Process.
Plan Loading and Access
Record parent-roll width, diameter, weight and core, then review the approach route and clearance at the separate unwind.
Thread and Establish the Cut
Confirm web guidance, tension requirements and blade positions using the intended material and lane pattern.
Build the Large Finished Rolls
Check core engagement, roll firmness and lane behaviour through the diameter build. Include roll stability and edge appearance in the trial.
Unload and Verify
Agree the unloading sequence, receiving equipment and operator access. Inspect finished width, roll formation and suitability for downstream unwinding.
Plan the Installation and Maintenance.
Review the floor plan, service clearance, roll-handling route and utilities before installation. Agree commissioning and operator-training requirements with the proposal. Keep the machine identification, shaft interfaces and blade dimensions available for maintenance and spare-part inquiries.
Compare the Alternatives.
Compare AF400 with A400 using the complete layouts and matched specifications: both configurations shown list 400 m/min and a 1,000 mm finished diameter. AF500 uses differential-shaft rewinding and lists a smaller 600 mm finished diameter at 500 m/min. Choose between roll requirements and winding construction before comparing speed.
BEFORE YOU SPECIFY
QFJ-AF400: Questions Buyers Ask.
Which working widths are shown?
The table compares 1,300, 1,600 and 1,800 mm unwinding widths. Include the actual web width, edge trim and roll weight when selecting a version.
Is 1,200 mm the finished-roll diameter?
The specification table lists a 1,200 mm parent-roll diameter and 1,000 mm finished-roll diameter. Specify both dimensions separately in your requirement.
Is automatic nonstop roll change included?
The listed configuration describes air-shaft winding and chain unloading. Any nonstop changeover, turret or automatic cutting function must be explicitly defined in the proposed machine scope.
What should be checked during a trial?
Agree material, slit pattern, speed and roll dimensions. Inspect edge quality, finished width, winding firmness and the planned unloading procedure.
