Rubber and polyurethane coverings for the paper production

Paper production is a continuous process that subjects rubber components to extreme conditions: constant humidity, high temperatures, contact with process chemicals, and uninterrupted work cycles. In this context, the choice of compound and the quality of the coating have a direct impact on production output, finished product quality, and the frequency of maintenance interventions.

A.Piovan designs and manufactures rubber coverings for rollers, sleeves, and rotating components used in the various stages of the papermaking process, from sheet formation to pressing, and from calendering to coating. Each compound is selected based on the type of paper produced, the machine speed, and the specific chemical-physical stresses of each application, ensuring uniform nip pressure, wear resistance, and dimensional stability over time.

What experience does A.Piovan offer its customers?

The paper industry requires rubber components that can withstand humidity, high temperatures, and continuous wear.

What products can A.Piovan supply?

Typical applications and compounds

Taking-up paper rollers

Roller coverings in rubber or in Polyurethane, both with excellent cut and abrasion resistance.

Press roller

High mechanical and hydrolysis resistance compounds, ensuring uniform sheet dewatering and long service life even under high loads and constant humidity

Calender rollers

High hardness (85-95 Shore A) for stable contact pressure in the nip, essential for sheet thickness uniformity and surface finish

Spreading and coating rollers

Smooth surfaces and compounds resistant to coating chemicals, for a regular and consistent product distribution across the full width of the sheet

Guide rollers and sleeves for continuous machines

Dimensionally stable compounds, designed to withstand continuous work cycles, vibrations, and repeated mechanical stresses

Technical insight

In paper production, the performance of the rubber coating has a direct impact on dewatering efficiency, sheet surface quality, and the continuity of the production process. The choice of compound must take into account the machine section involved, contact with water, steam, and chemical agents, and the mechanical stresses to which the coating is subjected during the production cycle.

Press roller coverings: high resistance to hydrolysis and wear, maintaining constant performance in sheet dewatering even under intensive production cycles
Calender roller coverings: uniform hardness and thickness along the entire length of the roller, for constant contact pressure and a regular surface finish
Spreading and coating roller coverings: smoothed surface for homogeneous product transfer, with good resistance to water-based dispersions and process chemicals
Resistance to humidity, steam, and chemical agents: the compounds maintain dimensional stability and adhesion to the metal core over time, reducing the frequency of regrinding interventions and machine downtime
