This versatile equipment allows efficient mass production of rain gutter systems demanded in building construction industry.
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.
