Double Layer Roll Forming Machine for Two Trapezoidal Roof Profiles

Double Layer Roll Forming Machine for Two Trapezoidal Roof Profiles

1. Machine Structure

The double layer roll forming machine features a middle-plate welded frame design, providing excellent rigidity, strength, and long-term stability.
It integrates two independent roll forming systems on one base, enabling the production of two different trapezoidal roof profiles without the need for an additional line.
This compact structure saves space, reduces investment cost, and enhances production efficiency.

2. Working Principle and Function

This machine is designed to automatically feed, form, cut, and stack sheets according to the pre-set program.
By simply switching the control system, the operator can select the upper or lower forming layer to produce the required profile.
It provides continuous and accurate forming, ideal for batch or customized production of roofing panels.

3. Raw Material and Sheet Range

It is suitable for galvanized steel (GI), pre-painted steel (PPGI), aluminum, and other metallic materials.
Typical raw material thickness: 0.3 mm – 0.8 mm
Coil width: 1000 mm – 1250 mm
The finished sheets have high precision, smooth surfaces, and consistent shape quality.

4. Transmission System

The equipment adopts a chain drive system, which ensures stable and synchronized power transmission between rollers.
Chain transmission is simple, reliable, and easy to maintain, making it suitable for long-term industrial production.
Combined with precision-machined rollers and hardened shafts, the forming process remains smooth and noise-free.

5. Control System and Operation

Equipped with a PLC automatic control system (with touchscreen interface), the machine offers full automation for feeding, measuring, cutting, and stacking.
Operators can set the sheet length, production quantity, and select the profile layer easily through the control panel.
It supports manual and automatic modes, ensuring flexibility and safety during operation.

6. Applications

This double layer forming machine is widely used for manufacturing roof and wall panels for industrial buildings, warehouses, workshops, residential houses, and commercial structures.
The two trapezoidal profiles can meet different market preferences and construction requirements, making it ideal for multi-profile roofing production.
