Scrap Chopper for 2200 mm Slitting Lines
On a 2200 mm slitting line the trimmed edges are long and heavy, so scrap handling has to keep pace with the line or the trimming section stops. This chopper takes the waste edge from the chute, chops it and drops it into the waste box for collection and recycling.
- Sized for 2200 mm slitting lines
- Double roller type with left and right racks
- Each side driven by its own motor, reducer and coupling
- Upper knife shaft drives the lower shaft through gear
Key Benefits
What wide line scrap handling needs.
Keeps Pace With A Wide Line
Independent drives on each side handle the scrap volume that a 2200 mm line generates without becoming the bottleneck.
Simple Collection And Recycling
Chopped edge pieces fall into the waste box, which makes collection and recycling straightforward.
Operator Out Of The Scrap Path
Continuous chopping removes the need to handle long ribbons of trimmed edge manually.
Where It Is Used
Where it sits.
- 2200 mm slitting lines
- Wide strip trimming sections
- Continuous processing lines with edge trimming
- Plants upgrading scrap handling capacity
Who It Is For
- Wide slitting line operators
- Plants with scrap handling bottlenecks
- Line builders supplying trimming sections
- Maintenance teams replacing an undersized chopper
Problems It Solves
- Scrap handling limiting trimming line speed
- Long ribbons of edge scrap jamming the chute
- Manual scrap handling on a wide line
- Uneven handling between left and right edges
Technical Features
Machine arrangement.
Double Roller Construction
Left and right racks each handle the shear strip from one side of the line.
Independent Side Drives
Left and right upper knife shafts are driven separately, each with its own motor, reducer and coupling.
Gear Coupled Shafts
The upper shaft drives the lower shaft through gear so both knife shafts stay synchronised.

Manufacturing Process
Scrap Volume Review
Trimmed edge width, thickness, material and line speed define the machine size.
Rack Fabrication
Racks are welded and machined for shaft alignment.
Shaft And Knife Production
Knife shafts and knives are produced and hardened.
Drive Assembly And Test
Drives are fitted per side and the machine is run tested.
Quality Control
- Rack machining and alignment inspection
- Knife hardness verification
- Gear mesh and lubrication check
- Drive function test per side
Customization Options
- Capacity for your edge width and thickness
- Drive rating to line speed
- Chute and waste box interface
- Left and right layout to the existing line
Use Guide
- Keep the edge chute clear and evenly fed
- Inspect knives for wear at planned intervals
- Check gear lubrication on both shafts
- Empty the waste box before it backs up
How It Compares
Against other scrap handling options.
| Edge scrap coilers | Chopping removes the handling and storage of long scrap coils. |
|---|---|
| Undersized choppers | A machine sized for 2200 mm trimming keeps up with the scrap volume rather than throttling the line. |
| Manual handling | Continuous chopping keeps the operator out of the scrap path and the line running. |

Scrap Chopper for 2200 mm Slitting Lines FAQ
What line width is this sized for?
2200 mm slitting lines. Other widths are configured from your trimmed edge dimensions and line speed.
How is it driven?
Double roller type with left and right racks. Each side has its own motor, reducer and coupling, and the upper knife shaft drives the lower shaft through gear.
What happens to the chopped scrap?
It goes from the waste edge chute into the chopper and the broken edge pieces are collected in the waste box for recycling.
Can it be retrofitted?
Yes. Send the trimming section layout, edge dimensions and line speed and we match the machine.
Do you supply replacement knives?
Yes, knives and knife shafts are available as spares.
What do you need to quote?
Trimmed edge width and thickness, material, line speed and available space at the trimming section.
