Ribbed Ridge Cap Tile Roll Forming Line

1. Definition

A ribbed ridge cap tile roll forming line (Chinese: 冲筋屋脊瓦 / 冲型屋脊瓦) forms ridge caps that include rib pressing, transverse rib punching, large-edge forming, and punch-style cutoff. English names include ribbed ridge cap tile roll forming machine. Servo drive and post-form punch-cut distinguish it from a plain continuous 312 English-quotation ridge mill.

Recommended baseline is the Chinese technical description for the ribbed ridge-cap machine. The neighboring 312 English quotation is a related but different configuration on the same ridge-tile leaf — never use 312 power or shaft figures as the punch-line answer.

Market ridge lines with hydraulic punch stations stamp raised tile shapes or perforations after (or during) forming to add longitudinal stiffness and appearance. That industry pattern matches this process family; keep tonnage and kW on the documented baseline below.

2. Process and applications

Documented process sequence:

1. Decoiling (about 3 t passive loading rack)
2. Guided strip entry
3. Rib-pressing roller section
4. Flat-sheet transverse rib punch
5. Large-edge forming roller section
6. Punch forming
7. Cutoff
8. Exit table

Documented composition also lists hydraulic station and industrial PC / PLC cabinet. Frame style: gantry / pillar with chain drive; full-shaft roller sections; servo motor drive for rapid accurate stops; punch and cut after forming.

Applications. Color-steel roof ribbed / punched ridge-cap production where the drawing requires embossed ribs or punch-formed tile geometry along the ridge cover. Not a trapezoid roof main line and not a substitute answer for plain 312 inquiries.

3. Reference parameters (ribbed-punch baseline)

4. Conflicts and open items

• Versus 312 baseline — 312: main about 3 kW, about 11 rollers, shaft about ø60, decoiler width about 1250 mm, thickness about 0.3–0.5 mm, speed about 8–12 m/min, yield strength about 245–350 MPa.
• Same leaf, different machines — Catalog navigation may group both ridge titles. Process and power remain separate.
• Market “hydraulic punching ridge” sheets — Public pages may show other speeds (for example about 5–10 m/min) or different motor splits. Industry context only unless the proposal cites them.

5. Boundaries (related machines)

• 312 ridge cap line — Continuous form + hydraulic cut without this rib/punch stack.
• Trapezoidal / IBR roof hosts — Main roof cover sheets.
• Glazed tile step lines — Decorative roof tiles with step press, not ridge accessories.
• Standalone punch presses — Not a substitute for this integrated ridge process line.

6. Buyer FAQ

Why is hydraulic power so much higher than on 312?

Because this line includes transverse rib punch and punch-cut stations after forming. The documented hydraulic station is about 11 kW versus about 3 kW on the plain 312 baseline.

Is 600 mm the finished ridge cover?

It is the documented strip width about 600 mm. Finished cover and rib pattern follow the drawing.

Can one machine run both plain 312 and ribbed punch without change?

Not as a casual claim. They are different process stacks and power baselines. Order to the ridge drawing you actually install.

Is this a roof trapezoid machine?

No. It produces ridge-cap accessories with rib / punch features, not full-width trapezoid roof sheets.
