Typical Ridge Cap Tile Line Process Flow

1. Definition

A ridge cap tile line process flow describes how coil becomes the metal cover along a roof ridge. Buyers usually meet two ZTRFM families on the same leaf: a simple 312-class flow (form then cut) and a ribbed punch flow (rib roll + multi-punch before cut). Publishing one merged flowchart without labels causes wrong power and speed quotes.

Industry pages commonly list uncoiler → feed → form → hydraulic cut → table; punching appears as optional or integrated depending on profile. Use that only as context — choose the family that matches the finished drawing.

2. Two process families

A. Simple 312-class ridge

1. Passive decoiler (~5 t class; width ~1250 mm; ID ~450–550 mm) pulled by the former
2. Feeding / guiding into roll stands
3. Multi-pass roll forming of the ridge crown and legs
4. Hydraulic shear (gear-pump driven); Cr12 quenched blades
5. Unpowered roller out-table

B. Ribbed punch ridge

1. Decoil → guide
2. Rib rolling → flat transverse rib punch
3. Edge forming → profile punch
4. Forming cut → discharge

• Simple covers replacing old pad-style ridge installs
• Ribbed / embossed ridge caps requiring punch tooling
• Always confirm ridge separately from glazed-tile or trapezoid main lines

3. Parameter anchors by family

Conflict call-out: glazed-tile side documents may show working speeds ~2–3 m/min for stepped tile — that is a different machine class. Do not use glazed working speed as the 312 ridge answer. One-out-of-three ridge quotes without full sections stay blocked.

4. Boundaries

• Not a trapezoidal roof-sheet main-line flowchart
• Not a glazed stepped-tile press-and-form cycle
• Not a standing-seam roof panel line
• Keep simple vs ribbed flows labeled on proposals and training docs

5. Buyer FAQ

Which flow should I put on the RFQ?

Attach the finished ridge drawing. If transverse ribs / emboss punches are required, use the ribbed punch sequence; otherwise start from the 312-class simple flow.

Is decoiler powered?

312 FAQ cites passive decoiler pulled by the former. Ribbed FAQ cites ~3 t passive loading rack. Powered hydraulic decoilers appear only when the named proposal lists them.

Where does length measurement sit?

Encoder + PLC length control on both families; exact brand follows the contract electrical list.
