Handling mesh rolls, sheet metal and coiled materials manually is tiring, risky and slows down production. Every day, operators across the metalworking sector face the same problem: how to move heavy materials without compromising safety and the quality of the work.
The solution? Motorised winders and unwinders custom-designed to meet the real needs of industrial processing.
Why choose motorised systems for roll handling
In the sheet metal and coil processing sector, time is money. Every minute lost in manual unwinding translates into:
- Production delays
- Increased operator fatigue
- Risk of material damage
- Potential workplace accidents
Motorised winders and unwinders eliminate these problems at source. Process automation allows you to focus on the quality of the work, not on the physical handling of the material.
Technical specifications of motorised winders and unwinders
The distinctive feature of these machines for processing sheet metal, and many other materials, is the 2150 mm-long shaft. This dimension ensures:
- Handling of wide rolls, ideal for wire mesh and industrial materials up to 2 metres wide
- Uniform load distribution, the length ensures stability even with heavy loads
- Structural rigidity, essential for continuous processing without deformation
- Adaptability to different formats and types of material
Motorisation and automation represent a significant improvement over traditional systems. Controlled movement allows for:
- Smooth and constant rotation
- Adjustable speed depending on the type of material
- A drastic reduction in manual effort
- Precise control of material tension
The operator no longer physically operates the roll. Their role becomes that of safely guiding the material, accompanying it as it unrolls to prevent twisting or creasing.
Tangible operational benefits
Motorisation eliminates repetitive movements and excessive strain. The operator maintains visual control of the material at all times without exposing themselves to physical risks. There are several positive outcomes:
- Fewer workplace accidents
- Reduced muscle fatigue
- A more ergonomic working environment
- Compliance with safety regulations
Measurable production efficiency
Modern motorised winders and unwinders immediately improve production KPIs:
- Reduced set-up times, quick and easy roll change
- Greater continuity, fewer stoppages for manual adjustments
- Consistent quality, uniform tension throughout the material
- Less waste, reduced damage caused by handling
Integration with production lines
These systems integrate seamlessly with motorised straightening machines and compact feeding lines, creating continuous, automated production flows. Synchronisation between motorised winders and unwinders and the rest of the line allows the entire production process to be optimised.
Industrial applications of motorised winders and unwinders
1. Metalworking sector
Metal mesh requires particular care during unwinding. The motorised system ensures:
- Control of flatness
- Absence of deformation
- Safe handling of sharp materials
- Precision in positioning
2. Construction and fencing production
In the production of industrial fencing, the speed of material preparation is crucial. An automatic system allows for:
- Processing more rolls per day
- Maintaining tight tolerances
- Reducing delivery times
- Increasing production capacity
3. Sheet metal warehouses and service centres
For those handling large volumes of coiled material, the automation of the uncoiling process is essential to remain competitive and meet customer demands.
Case study: the results of automation
A metal mesh manufacturing company was handling 500 kg coils using manual systems.
Before automation:
- 2 operators required for each roll change
- 15 minutes of machine downtime per change
- Recurring minor accidents
- 5% material waste
After installing motorised winders and unwinders:
- Just 1 operator required
- 5 minutes per roll change
- Zero accidents in 12 months of use
- Productivity increased by 18%
- Waste reduced to 2%
Types of materials that can be handled
Modern motorised systems are designed to work with:
- Electro-welded, expanded and woven metal mesh
- Steel, aluminium and stainless steel coil sheets
- Galvanised and pre-painted coated materials
- Magnetic strips for electrical engineering applications
- Special materials as copper, brass and special alloys
The versatility of motorised winders and unwinders makes them suitable for a wide range of production environments.
Maintenance and long-term reliability
A well-designed system requires minimal maintenance. Routine checks include:
- Lubrication of shaft bearings
- Checking the tension of drive belts
- Checking the operation of the electric motor
- General cleaning to remove processing residues
- Inspection of safety devices
With scheduled routine maintenance, the system’s reliability remains high for years, ensuring production continuity.
