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.
