Gutter Cover / Leaf Guard Machines
1. A lid, not a trough
A gutter cover / leaf guard sits on the eaves trough and lets water in through punched slots or mesh. The roll former makes that lid. It does not make the K-style or half-round channel underneath. Dry-fit against the gutter drawing is the acceptance visual.
2. Named cover line
Process-library order sheet:
| Station | On that specification |
|---|---|
| Material | PPGI 0.4–0.5 mm |
| Punch | 55 t press, servo feed, Cr12 die ×1, punch feed 0–30 m/min |
| Form | 13 stations, shaft Ø50, GCr12 rolls, main 7.5 kW, ≥20 m/min |
| Cut / stack | Hydraulic stop-cut 5.5 kW; 4 m arm auto flip stack |
| Power | 240 V / 60 Hz / 3φ |
Punch feed 0–30 m/min and form ≥20 m/min are two stations, not one mill speed. The press writes the pattern; the mill then forms the silhouette.
3. Why the press is first
Slots punched after the lid is formed sit on a curved surface and walk. The 55 t station is not a 300 t guardrail punch and not a purlin 15 kW cut+punch tank. It is the leaf-guard pattern press on this cover line.
4. Mesh notch dies are not the mill
A companion process is a mesh corner-notch die kit (oblique cuts for cover mesh). It can ship with the cover RFM. It is not a second 13-station host. Mold-only accessory sheets have their own pages.
5. Open gutter hosts stay off this quote
| Family (gutter-type wiki) | On the open-gutter quotation |
|---|---|
| Half-round 6-inch | ~3–8 m/min; ~5.5 + 3 kW; φ50 / ~18; ~0.4–0.8 mm |
| Rain / K-style class | ~10–12 m/min; ~4.0 + 3.0 kW; φ70 / ~18; ~0.3–0.7 mm |
| Box gutter | Ratings stay on the box proposal — still not a cover mill |
End-cap punching is another accessory. Downpipe and elbow are pipe work.
6. Dry-fit drawing
- Cover section that matches the gutter it sits on
- Hole / slot / mesh pattern
- Whether corner-notch dies are in the crate
- Stack: auto flip vs tables
- Hall voltage — this named line is 240 V/60 Hz/3φ
7. Buyer FAQ
Can the rain-gutter mill run covers by changing rolls?
Not as a silent option. Cover duty includes a 55 t pattern press and a lid flower. Quote the cover line.
Is 55 t the forming force?
No. Forming is 13 stations at 7.5 kW. 55 t is the punch.
Does the cover line make the gutter too?
No. Two products, two hosts, unless the order lists both.
7.5 kW / 55 t / 240 V are labeled to the cover RFM sheet. Commercial terms come back on the offer.
