Box Panel Machine (Hoist-Change Dual-Host Configuration)

1. Definition

A box panel machine cold-forms enclosed box-style shelf boards for racking and retail shelving. The reference configuration uses two hanging forming hosts (A/B) so two box profiles share one plant: hoist swaps the active host; split roller tracks allow manual single-side width trim.

It is not an ordinary single-host deck panel line, not a back-panel servo-width line, and not a welded / clinched box beam for pallet-rack horizontals.

2. Process flow

1. 5 t passive loading
2. Guide infeed
3. Two-roll convey with optional protective film
4. Optional front cut
5. Punch side notches + holes
6. Roll form on host A or B (hoist-change)
7. Cut-to-length + flange both ends
8. Exit table

Market “shelf panel box” pages emphasize pre-punch/notch and width change (hand wheel or servo). They illustrate the product family; dual hanging hosts remain the distinctive story on this proposal.

3. Reference parameters

4. Boundaries and conflicts

• Do not copy deck-panel ~30 stands / ~11 kW / ~6–8 m/min onto box panel.
• Do not copy back-panel ~0–6 m/min / ~27 kW total / 0.4–0.6 mm here.
• Box beam roll forming (rack horizontals) is a different product family.
• Public “box plate” guides may quote broad width/speed ranges — use only as industry context, not averaged ZTRFM ratings.

5. Applications

Plants that must produce two box-style shelf boards and want hoist-change host swap instead of a second full line. Typical buyers: warehouse shelving and supermarket box-board fabricators.

6. Buyer FAQ

Why two hosts instead of one adjustable deck?

A and B roller sets form different box geometries. Hoist swap changes the entire forming path; split-track trim handles width within a profile family.

Can I paste deck 30-stand / 11 kW numbers?

No. Those belong to the deck / shelf panel configuration.

Is film coating mandatory?

Optional on the convey section. Specify if finished boards need surface protection before punch and form.

What about front cut?

Listed as optional before the notch/hole punch. Include it only when the named BOM requires pre-cut blanks.
