Typical Process Flow — Glue Configuration (Rockwool/EPS Composite Line)

1. Definition

This page maps the glue configuration of an EPS / rockwool composite panel plant: roll-formed metal skins are bonded to pre-cut core boards with sprayed adhesive and heat, then flying-sawn to length. It is not a continuous full-core polyurethane foam mill, and it is not a PU-edge rockwool continuous plant. Core infeed on the recommended quotation is typically manual into the composite machine.

2. Operating sequence

1. Decoil (multiple stations common — recommended quote lists about four × 5 t manual decoilers)
2. Upper sheet roll form (roof trapezoid profile optional / customizable)
3. Glue spray + infrared / heat composite with EPS or rockwool core boards and lower skin
4. Flying saw cut-to-length
5. Exit tables / collect (about dual 3 m tables on the recommended list)

Industry EPS line explainers describe the same spine — decoil → form → glue / heat laminate → cut — as background. Station names and automation level still follow the named proposal.

3. Typical units (recommended quote class)

• 5 t manual decoilers ×4
• Chain-drive upper former (~14 stands; shaft ø80; main about 3 kW; H-beam frame)
• Composite machine with dual glue systems and heating
• Dual Delta PLC-class desks
• Flying saw (~5.5 kW cut motor)
• Dual exit tables (~3 m class)

4. Speed and power checkpoints

5. Boundaries

• Not continuous PU foaming — no high-pressure full-core foam head + long double-belt cure as the primary bonding method.
• Not PU-edge rockwool continuous — no dedicated PU side-seal foam station as the defining process.
• Not automatic rockwool slit-and-flip — do not describe the recommended glue quote as a full continuous mineral-wool handling plant.
• Keep forming-station speed separate from composite line speed in every commercial answer.

6. Buyer FAQ

Where is the PU edge foam station on this flow?

It is not on this glue flow. PU edge sealing belongs to the PU-edge rockwool process page. This configuration bonds with adhesive and heat only unless a contract explicitly adds edge options.

Is the upper former’s 12 m/min the plant capacity?

No. About 12 m/min is a forming-station work speed on the recommended sheet. Whole-line / composite work is about 5 m/min — publish both labeled, never one merged “EPS speed.”

Can rockwool boards run on the same glue sequence?

Yes as a core option on the glue configuration — EPS or rockwool boards are hand-fed into the composite machine on the recommended wording. That still does not turn the plant into a PU-edge continuous rockwool line.

Why does another sheet show ~28 kW / 0–4 m/min?

That is a short-table coexist band in the same family. Name which quotation the proposal follows; do not average 50 kW with 28 kW into one public figure.
