Working Principle of Downspout Roll Forming Machine

The working principle involves unwinding coil material, followed by progressive bending through rollers to form a longitudinal box-type profile:

Uncoiling – The metal coil strip is loaded on an uncoiler which allows it to unwind freely.

Feeding – The strip is fed into the roll forming section through automated feeding rolls.

Roll Forming – As the strip passes through each stand, it is gradually bent into the desired rain gutter profile.

Cutting – After the final forming, the continuously produced gutter is cut into required lengths by a cutting machine.

Output – The cut gutters slides onto the output table and are collected for further processing.

The roll forming shapes the flat metal strip into a longitudinally bent gutter profile by applying a series of bends along the length.

Types of Downspout Roll Forming Machines

China downspout roll former comes in different configurations:

Based on Automation

  • Manual – Stop for manual cutting after each gutter piece
  • Semi-automatic – Auto-cut at preset length, manual coil feeding
  • Fully-automatic – Automatic uncoiling to output

Based on Production Speed

  • Low speed – 10-15 m/min
  • Medium speed – 15-30 m/min
  • High speed – 30-50 m/min

Based on Size Capacity

  • Small size – Gutter width upto 150 mm
  • Medium size – Gutter width upto 300 mm
  • Large size – Gutter width above 300 mm

So customers can select type based on automation needs, required output and gutter dimensions.
