Tissue Rollers: Why Choosing the Right Component Matters from the Start 📌
Tissue rollers of large dimensions require a carefully planned production cycle, starting from the raw material and reaching centesimal, and in some cases, micrometric finishes. In modern high-output paper mills and related facilities, the quality of rollers determines process stability, machine wear, and production efficiency. 💡
Materials and Treatment: Steel Rollers vs Aluminum Rollers 🔩
For components with a diameter of 510 mm and a weight of 3,500 kg, material selection is crucial. Steel roller s provide rigidity, thermal stability, and durability under high loads, making them the standard choice for heavy-duty applications. Aluminum rollers are used only when lightweight design is a priority or in hybrid solutions with a steel core and light alloy shell. 🧪
Surface treatments such as nitriding, protective coatings, or ceramic layers significantly extend the operational life of the components. For some clients, functional layers and surface hardness control are already a standard. 🔬
Multiple Applications: Paper Mill Rollers and Beyond 🔄
The technology applied to Tissue Roller s is also applicable to other sectors: we supply paper mill rollers, rollers for conversion lines, and rollers for specialized facilities. Our processes ensure high performance even in demanding applications. 🔁
Beyond paper mills, we manufacture components for other sectors: sheet metal roller s for the steel industry, printing machine roller s for high-precision printing, and flexible packaging rollers for lamination and printing lines. Each application requires specific tolerances and surface finishes. 🧰
Production Process: From 5-Axis Turning to Precision Grinding 🔧
The typical sequence for a roller of this type involves multi-axis turning and final grinding. On our Emco HT 200 5-axis lathe, we remove excess material and define functional profiles while minimizing residual stresses. Then, grinding on the Danobat G91/6000 CN ensures cylindricity, concentricity, and surface roughness that meet the strictest specifications. ⚙️
This workflow also allows us to produce special rollers and shafts with custom fittings and tolerances. Our experience covers complex shaft assemblies, precision threads, and bearing seats with tight tolerances. 🔩
Special Rollers and Shafts: Customization for Every Plant 🧩
When supplying special rollers and shaft s, we can include secondary operations such as milling, through-holes, dynamic balancing, and certified balancing. These steps are essential for rollers operating at high speeds or in installations where vibration reduction is a key requirement. ✅
Quality, Testing, and Control: Ensuring Long-Term Performance 🔍
Our dimensional and surface inspections include, where required, roughness measurement, cylindricity control, and non-destructive testing. This approach applies both to paper and cardboard roller s and to rollers used in metalworking or printing. Certified tests reduce the risk of unplanned downtime and improve maintenance predictability. 📈
Served Sectors: Paper and Cardboard Rollers and More 📦
We manufacture components for a wide range of sectors: paper and cardboard rollers, printing machines, lamination lines, and metalworking. Custom solutions allow us to meet requirements for surface quality, durability, and chemical or process fluid compatibility. 🧾⚙️
In metalworking, sheet metal rollers and forming rollers are designed to withstand high stress and abrasive wear. Printing machine components must guarantee consistent finishes and high dimensional accuracy. 🖨️
Operational Sustainability and Predictive Maintenance 🌱
The adoption of monitoring sensors and predictive maintenance systems extends component life and reduces operating costs. Our flexible packaging roller s can be supplied with thermal and vibration sensor predispositions per customer specifications, enabling targeted interventions and reducing unplanned downtime. 📊
