SLITTING & REWINDING · QFJ-A500
Compare a horizontal differential-shaft configuration for converting film, composite webs, foil and paper. The A500 combines a listed 500 m/min slitting speed with an 800 mm parent-roll diameter and 600 mm finished-roll diameter.
Listed configuration values. Production speed and practical slit pattern depend on the material and the agreed machine setup.
A horizontal layout to assess when you need several slit lanes rewound on differential shafts and the parent and finished rolls fit the listed capacities. Start with the web structure and required roll firmness, then review the working width and lane pattern.
CONSTRUCTION & CONTROL
The winding arrangement uses differential shafts, with each winding shaft controlled by a separate servo motor. This construction is relevant when reviewing differences between slit lanes and the winding conditions required across a production run.
The connected construction brings the converting stages into one horizontal arrangement. Compare the complete footprint, roll-loading route and operator access with your available production space.
The configuration lists four sets of servo motor control. The width-specific drive ratings below help define the proposed version; they should be reviewed with the electrical supply and operating duty.
An 800 mm incoming-roll diameter and 600 mm finished-roll diameter set the initial comparison. Confirm roll weight, core size and shaft loading separately; diameter alone does not establish load capacity.
MATERIAL & FINISHED ROLL
Discuss PVC, BOPP, CPP or PET by thickness, treatment, surface sensitivity and roll format. The polymer name is only the starting point for choosing cutting and winding conditions.
Describe every layer, including coatings, laminates and release surfaces. Assess web contact, tension and finished-roll build against the complete construction.
Provide paper grade and grammage, or foil grade, thickness and temper. Agree the edge-quality requirement and review the knife arrangement for the actual material.
WIDTH & DRIVE CONFIGURATIONS
| Parameter | 1300 configuration | 1800 configuration |
|---|---|---|
| Unwinding width | 1,300 mm | 1,800 mm |
| Listed slitting speed | 500 m/min | 500 m/min |
| Minimum slit width | 20 mm | 20 mm |
| Parent-roll diameter | 800 mm | 800 mm |
| Finished-roll diameter | 600 mm | 600 mm |
| Main servo power | 4 kW | 5.5 kW |
| Rewinding servo power | 2 × 4 kW | 2 × 4 kW |
| Unwinding servo power | 5.5 kW | 7.5 kW |
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
Record roll width, diameter, weight, core and material condition before planning loading and threading.
Confirm guiding and tension requirements, blade arrangement and lane positions using the intended material and slit pattern.
Review differential-shaft setup, core fit and winding firmness across the lanes. Include acceptable edge and roll appearance in the trial.
Check finished width, diameter, roll build and suitability for the next process. Plan handling and removal around the actual roll weight.
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.
Choose A500 as a starting point for an integrated horizontal differential-shaft layout. Compare B500 where a vertical format and smaller rolls suit the task; compare A400 where larger parent and finished diameters are needed. These formats differ in construction and capacity, so the speed alone should not decide the selection.
BEFORE YOU SPECIFY
It is a listed speed for the configuration. The achievable production speed depends on the web, slit pattern, winding requirement and confirmed equipment setup.
Choose against the actual parent-web width and trim requirement. The table compares the 1,300 and 1,800 mm configurations; include any other width requirement in your inquiry.
They are separate configurations. The A500 lists an 800 mm parent-roll diameter; the AF500 split layout lists 1,200 mm. Review a matching layout and specification before comparing offers.
Include material construction and thickness or grammage, parent width/diameter/weight/core, finished widths/diameters/cores, lane count, desired production conditions and installation constraints.
MATERIAL & PRODUCTION REQUIREMENTS
Compare material requirements and winding formats before defining the final machine configuration.
QUOTATION & SUPPLY SCOPE
Request a QFJ-A500 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.
Ask for standard equipment and optional items to be listed separately. Include commissioning, operator training, documentation and initial spare-part requirements in the discussion.
Provide quantity and destination. Confirm price, currency, delivery basis, packing, production schedule and any excluded freight or import charges in the quotation.
Agree representative material inspection, measurement criteria and supplied configuration before ordering. Confirm warranty terms, installation responsibilities and spare-part support with the proposal.
