Small-Core Rewinding
The machine is described for rewinding around smaller tube cores. Agree the actual core dimensions, core material and finished-roll requirements rather than assuming a standard core size.

FJ-B Small-Core Rewinding Machine
Prepare smaller finished rolls with the FJ-B rewinding range. Compare the 200 m/min configuration with 600 / 200 mm parent / finished diameters and the 300 m/min configuration with 1,000 / 300 mm diameters.

Listed configuration values. Production speed and practical slit pattern depend on the material and the agreed machine setup.
Where This Configuration Fits.
Consider FJ-B when the task is rewinding into smaller tube cores and finished diameters. Define the actual core inside diameter, wall thickness, finished width and roll length. The two configurations below have different roll envelopes and must be assessed separately.
CONSTRUCTION & CONTROL
Look Inside the Machine Format.
Two Distinct Roll Envelopes
The 200 m/min version lists 600 mm incoming and 200 mm finished diameters. The 300 m/min version lists 1,000 and 300 mm respectively; these are separate configurations, not interchangeable limits.
Independent Loading on the 300 Version
Independent shaft loading is listed for the 300 m/min configuration. Review the loading route, core interfaces and roll mass with the proposed arrangement.
Finished-Roll Preparation
Plan roll length, winding direction, firmness and removal around the next production stage. Any slitting, length-control or automatic handling function should be explicitly identified in the supply.
MATERIAL & FINISHED ROLL
Define the Web You Need to Convert.
Wallpaper and Paper
Provide paper construction, coating, width and finished-roll length. Review surface marking and firmness against storage and downstream use.
Plastic and Composite Films
For PVC, BOPP, CPP, PET and composite films, specify thickness, stretch and layer structure. Small cores require review of winding conditions for the actual material.
Aluminium Foil
Identify grade, temper and thickness with acceptable edge and surface condition. Agree the core and roll build using representative material.
PROCESS & CONFIGURATION
FJ-B Technical Specifications.
| Parameter | 200 m/min configuration | 300 m/min configuration |
|---|---|---|
| Listed rewinding speed | 200 m/min | 300 m/min |
| Parent-roll diameter | 600 mm | 1,000 mm |
| Finished-roll diameter | 200 mm | 300 mm |
| Loading arrangement | Confirm with proposal | Independent shaft loading |
| Core inside diameter | Specify for application | Specify for application |
Listed values describe the configuration shown. Confirm working width, roll mass, core interfaces, voltage, frequency and the complete supplied scope in the proposal. Production conditions and acceptance criteria depend on the actual material.
SETUP, OPERATION & ACCEPTANCE
From Parent Roll to the Next Process.
Select a Configuration
Choose the starting roll envelope by parent and finished diameter, then confirm width, mass and core dimensions.
Define the Finished Format
State target width, roll length or diameter, core specification and winding direction. Confirm the functions needed to control the output.
Review Loading and Changeover
Assess access, core preparation, loading and finished-roll removal for the selected configuration.
Check Downstream Use
Inspect roll length, surface condition, firmness and unwind behaviour at the next process under agreed trial conditions.
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.
FJ-B is a rewinding starting point for small finished rolls. Compare A200 or A500 when a defined multilane slitting arrangement is central to the task. LM400 addresses a much larger roll envelope.
BEFORE YOU SPECIFY
FJ-B: Questions Buyers Ask.
What is the smallest core size?
A core-size limit is not stated in the available specification. Send inside diameter, wall thickness, material and finished-roll mass for compatibility review.
Are the 200 and 300 m/min versions the same machine?
They have different listed parent and finished diameters. Request the layout and complete specification for the chosen version.
Is slitting included?
Do not assume a slitting system from the rewinding designation. Specify lane widths and cutting requirements so the quotation identifies any supplied knife arrangement.
Are automatic length control and roll changes standard?
These functions are not established by the listed speed and diameters. Include them as requirements and confirm the included scope in the proposal.
QUOTATION & SUPPLY SCOPE
Specify Your FJ-B Supply.
Request a FJ-B quotation against your material, working width and finished-roll targets. Identify the selected version, cutting and winding arrangement, loading equipment and controls in the proposed supply.
Compare the Included Scope
Ask for standard equipment and optional items to be listed separately. Include commissioning, operator training, documentation and initial spare-part requirements in the discussion.
Agree the Order and Delivery Details
Provide quantity and destination. Confirm price, currency, delivery basis, packing, production schedule and any excluded freight or import charges in the quotation.
Define Acceptance and Support
Agree representative material inspection, measurement criteria and supplied configuration before ordering. Confirm warranty terms, installation responsibilities and spare-part support with the proposal.
