UNK600 is best understood as a sequence of controlled handoffs. The saved configuration combines servo drive, an HMI, buffered tension control, automatic web guiding and a full-surround waist structure. Each station can run, yet the finished diaper is acceptable only when the references carried from one station to the next remain aligned.

Identify the hydrophilic topsheet, hydrophobic leg-cuff nonwoven, ADL, fluff pulp, SAP, tissue or nonwoven wraps and PE film by supplier lot. Winding direction and roll edge should be recorded before loading.
The pulp, SAP and upper and lower wrap materials establish the core that later stations must hold in position. The approved sample and recipe provide the reference; the historical page does not state a universal dosage.
Topsheet, backsheet, leg-cuff materials, elastics and ADL meet around the core. Servo synchronization and digital size change are recorded functions, but every planned size still needs its own recipe and measured sample.
Nonwoven and elastic for the big waistband, together with the S-cut hook and glue materials listed in the source, create the defining U-shape construction. Registration after a splice or restart is a product-quality checkpoint, not merely a machine-motion check.
The old scope says the automatic stacker and packaging machine are to be defined by the customer. Pack count, discharge direction and communication with downstream equipment therefore belong in the project boundary.
The legacy description records a tension system with a buffer and automatic web guiding intended to support zero-speed splicing. That statement should be translated into a station list: which rolls can splice without stopping, where accumulation is available, which guide controls each web, and how many products are isolated after a join. A splice trial is complete only when the team records the roll, time, alarm response and first accepted diaper.
| Recorded item | Legacy value | Flow decision it affects |
|---|---|---|
| Design speed | 550 ppm | Mechanical reference for the configured route |
| Stable working speed | 450-500 ppm | Timed-run target to verify with named materials |
| Dimensions | 24 m x 4 m x 3.6 m | Unwind, service and downstream layout |
| Installed capacity | 300 kW | Electrical distribution planning |
| Air pressure | 0.6-0.8 MPa | Pneumatic supply check |
| Machine weight | 70 tons | Foundation, unloading and lifting plan |
The same table lists rejection at no more than 3 percent and efficiency at no less than 85 percent. Their counting rules are not defined in the old page, so HAINA should place the definitions, exclusions and sample interval in the signed FAT protocol.
Three references should meet at this station: the chassis centerline, the incoming waist-web edge and the elastic position after recovery. Inspection should include the first pieces after startup, every splice and every size change. A visually correct empty run does not replace a trial with the buyer's approved nonwoven, elastic, hook and adhesive grades.
The saved scope names an operating-side guard, emergency-stop switch, safety identification and a pull wire on the drive side. Acceptance should test each device in the state where it is intended to stop the line. The stacker and packer require a separate ownership table covering supply, controls, reject handling and recovery after a downstream stop.
No. It is recorded as design speed. The legacy stable working range is 450-500 ppm, and saleable output also depends on the agreed efficiency, rejection definitions, product size, materials and packaging boundary.
The historical text says the automatic stacker and packaging machine are to be defined by customer need. The final quotation must state exactly what is included.
Use the contracted waist nonwoven, elastic, hook and adhesive, then retain products before and after the splice. Position, recovery and reject handling should be measured against the approved sample.
