Centre-Surface Contact Winding
The roll is formed using a centre-surface contact arrangement. Assess web contact, winding firmness and the acceptable finished-roll structure against your actual substrate.
SLITTING & REWINDING · QFJ-C400
QFJ-C400 Centre-Surface Slitter Rewinder
Review centre-surface contact winding for film, composite webs, aluminium foil and paper. The C400 combines separate servo control for each winding shaft with a listed 400 m/min speed and 600 mm finished-roll diameter.
- Listed speed
- 400 m/min
- Minimum slit by width
- 5 / 10 mm
- Parent-roll diameter
- 1,200 mm
- Finished-roll diameter
- 600 mm
Listed configuration values. Production speed and practical slit pattern depend on the material and the agreed machine setup.
Where This Configuration Fits.
Start with the C400 when centre-surface contact winding is relevant to the finished roll you need. The winding contact, web sensitivity and narrow-lane requirements should be reviewed together. The separate-layout configuration shown here lists a larger parent-roll diameter than the connected-layout version.
CONSTRUCTION & CONTROL
Look Inside the Machine Format.
Individually Controlled Winding Shafts
Each winding shaft uses a separate servo motor. The configuration lists four sets of servo control, with drive entries varying by working width.
Width-Dependent Narrow Slitting
The 1,300 mm configuration lists a 5 mm minimum slit, while the 1,800 mm configuration lists 10 mm. Select the width and slit pattern together rather than applying one minimum across all versions.
Two Layouts, Different Parent Capacity
The separate layout lists a 1,200 mm parent-roll diameter. A connected-layout C400 lists 800 mm, with a 600 mm finished diameter. Identify the layout explicitly in your request.
MATERIAL & FINISHED ROLL
Define the Web You Need to Convert.
PVC, BOPP, CPP and PET Films
Specify film grade, thickness and any surface treatment or coating. Confirm that winding contact suits the surface and finished-roll requirement.
Composite Film and Aluminium Foil
Describe layers, contact sensitivity and required edge condition. Review cutting and rewinding as one process, especially for narrow lanes.
Paper Rolls
Provide grade, grammage, width and roll dimensions. Include dust, coating marks and winding firmness among the trial checks where relevant.

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.
Choose the Layout
Define parent-roll dimensions, weight and the available floor plan. Select separate or connected construction against loading and installation needs.
Establish the Cut
Match the working width and slit pattern. Confirm the blade arrangement and lane handling using the actual web.
Review Winding Contact
Assess contact conditions and finished-roll firmness. Include surface marking or compression limits where they affect downstream use.
Check the Narrow Rolls
Inspect slit width, edge condition, roll build and how the finished rolls unwind. Agree the trial speed and conditions before evaluating the result.
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 C400 with C200 when reviewing centre-surface layouts and control requirements: C200 uses magnetic-powder tension control for the winding shafts and lists 200 m/min. A500 and B500 use differential-shaft arrangements instead. Compare contact conditions and the intended roll structure when choosing between winding principles.
BEFORE YOU SPECIFY
QFJ-C400: Questions Buyers Ask.
Can every C400 configuration slit to 5 mm?
The 1,300 mm configuration shown lists 5 mm; the 1,800 mm configuration lists 10 mm. Material and cutting conditions must also support the required lane pattern.
Which parent-roll diameter applies?
The separate layout lists 1,200 mm, while the connected layout lists 800 mm. Confirm the selected layout in the proposal and match it to the incoming roll.
Does surface contact suit every coated film?
Contact suitability depends on coating, friction, marking sensitivity and winding requirements. Assess a representative material before confirming the configuration.
What information helps with narrow-roll inquiries?
Include web construction and thickness, working width, number of lanes, each slit width, finished core and diameter, edge requirements and the intended next process.
