Working Principle of U Profile Roll Forming
The working principle involves cold progressive roll forming of sheet metal strip through a series of roller stations.
- Process steps:
- Decoiling – Feed metal coil strip
- Feeding – Pull through forming stations
- Pre-punching – Punch holes if needed
- Forming – Incremental bending by roller dies
- Cutting – Cut on length
- Output of formed U channel
Forming Method
The sheet metal is subjected to repetitive incremental bending steps by roller dies arranged in a straight line. The roller stations continuously form the flat strip into the U-shaped channel through a series of small bends along the process line, without application of external heat.
