Workshop Services for Industrial Rolls & Cylinders

Maintenance, grinding, coating, balancing and new roll solutions

Industrial rolls, cylinders and rotating components are critical to reliable production. Their geometry, mechanical condition, surface properties and balance can directly influence equipment performance, product quality and component lifetime.

PR Rolls provides comprehensive workshop services for new and existing industrial rolls, cylinders and rotating equipment.

Existing components can be inspected, maintained, ground, restored, recoated and balanced to extend their service life. For newly manufactured rolls and cylinders, PR Rolls provides functional coatings, precision surface finishing and balancing according to the requirements of the application.

PR Rolls also manufactures new spreader rolls and provides complete maintenance and refurbishment services for existing spreader rolls.

Through our cooperation with AP Tela Oy, we can also provide solutions where AP Tela manufactures new industrial rolls and cylinders and PR Rolls applies the required functional coating and surface finish.

Our workshop capabilities are particularly suited to the pulp, paper and board industries, while coating, grinding, balancing and refurbishment services are also available for suitable components from other process and manufacturing industries.

From a new coated roll to the complete refurbishment of an existing production component, PR Rolls provides the workshop and surface engineering expertise required throughout the component lifecycle.

Complete Workshop Services – From New Component to Refurbishment

 

A roll or cylinder should be considered as a complete functional component.

Reliable performance depends on several factors working together:

• Mechanical condition
• Geometry and dimensional accuracy
• Bearings and related components
• Surface condition
• Coating properties
• Surface roughness and finish
• Dynamic balance

PR Rolls can combine several workshop operations within one coordinated project.

For an existing component, a typical process can include:

Incoming inspection → Measurement → Disassembly → Mechanical maintenance → Grinding → Surface preparation → Coating → Precision finishing → Dynamic balancing → Final inspection

For a new component, the process can include:

Incoming inspection → Measurement → Surface preparation → Functional coating → Precision grinding / finishing → Dynamic balancing → Final inspection

The exact scope is determined according to the component, its condition, application and required final performance.

The objective is to deliver a roll, cylinder or rotating component with the mechanical condition, geometry and functional surface required for reliable operation.

Industrial Roll Maintenance & Refurbishment

Extend the lifetime of existing production assets

Industrial rolls operate continuously under mechanical loads and demanding process conditions. Over time, wear, corrosion, coating deterioration and mechanical damage can affect both the roll surface and the component itself.

Typical reasons for workshop maintenance include:

• Worn or damaged surfaces
• Deteriorated coatings
• Bearing maintenance requirements
• Corrosion
• Scratches and grooves
• Dimensional deviations
• Uneven wear
• Mechanical damage
• Imbalance
• Changed surface requirements

 

PR Rolls evaluates the actual condition of the component before determining the appropriate maintenance scope.

Depending on the condition, the solution can combine mechanical maintenance, grinding, machining, surface restoration, coating, precision finishing and dynamic balancing.

Where technically and economically appropriate, refurbishment can extend the service life of an existing roll or cylinder and reduce the need for premature replacement.

Coating of New Rolls & Cylinders

Engineer the functional surface before the component enters production

Functional coating is not only a method for restoring worn components.

PR Rolls also coats newly manufactured industrial rolls and cylinders.

The base material provides the structural properties of the component, while the coating creates the functional surface that interacts with the production process.

Depending on the application, the surface can be engineered for properties such as:

• Wear resistance
• Corrosion resistance
• Release
• Non-stick performance
• Grip and traction
• Controlled surface roughness
• Resistance to contamination
• Long-term surface durability

PR Rolls selects the coating and final surface according to factors such as:

Component → Substrate → Process position → Operating environment → Wear mechanism → Required surface functionality

After coating, the component can be ground and precision-finished to achieve the required final surface. Where required, dynamic balancing can also be performed before delivery.

This enables PR Rolls to provide complete surface solutions for new rolls and cylinders before they enter production, as well as recoating of components already in service.

New Rolls & Cylinders in Cooperation with AP Tela Oy

Roll manufacturing combined with PR Rolls surface engineering

When a completely new industrial roll or cylinder is required, PR Rolls cooperates with AP Tela Oy.

AP Tela Oy manufactures the new rolls and cylinders, while PR Rolls provides the required functional coating and surface finishing.

This combines component manufacturing with PR Rolls' expertise in coating and surface engineering.

A typical delivery can include:

New roll or cylinder manufacturing by AP Tela Oy → Surface preparation → Functional coating by PR Rolls → Precision finishing → Dynamic balancing where required → Ready for installation

The coating and final surface are selected according to the intended process position and operating environment.

This cooperation gives customers access to both new coated components and refurbishment of existing production assets.

When the new component eventually requires maintenance, PR Rolls can inspect, grind, recoat, finish and balance it for continued production.

Spreader Rolls – New Manufacturing & Refurbishment

Complete spreader roll solutions for web handling applications

Spreader rolls are used in web handling applications to help spread the web, reduce wrinkles and support stable web travel through the production process.

PR Rolls manufactures new spreader rolls and provides complete maintenance, coating and refurbishment services for existing spreader rolls.

Depending on the application, PR Rolls can provide:

• Manufacturing of new spreader rolls
• Inspection and condition assessment
• Mechanical maintenance
• Surface restoration
• Grinding and precision finishing
• Functional coating and recoating
• Balancing where applicable
• Final inspection

For an existing spreader roll, PR Rolls can evaluate whether maintenance, refurbishment or replacement with a new roll is the most appropriate solution.

For new spreader rolls, the mechanical construction and functional surface can be designed around the requirements of the application.

The objective is not simply to supply a roll.

The objective is to provide the geometry, mechanical function and surface characteristics required for reliable web handling.

Spreader Roll Coatings

Surface properties for controlled web handling
The surface of a spreader roll plays an important role in its interaction with the web.

Depending on the application, specific properties may be required related to:

• Grip
• Non-stick
• Wear resistance
• Release
• Surface roughness
• Surface durability

PR Rolls can apply functional coatings to both new and existing spreader rolls, selecting and finishing the surface according to the intended operating conditions.

For an existing spreader roll:

Inspection → Maintenance → Surface restoration → Coating → Precision finishing → Final inspection

For a new spreader roll:

Manufacturing → Surface preparation → Functional coating → Precision finishing → Final inspection

This combination of mechanical and surface engineering expertise allows PR Rolls to treat the spreader roll as a complete functional component.

Recoating & Surface Restoration of Existing Rolls

Restore the component before creating the new functional surface

When an existing coating reaches the end of its useful life, the condition of the roll underneath should also be considered.

Wear, corrosion and previous operating conditions may have affected both the surface and the underlying geometry.

Depending on the condition, PR Rolls can provide a complete restoration process:

Inspection → Coating removal → Measurement → Grinding → Surface restoration → Surface preparation → Recoating → Precision finishing → Dynamic balancing

This allows the underlying component and its new functional surface to be addressed within the same workshop project.

The result is not simply a recoated roll.

It is a refurbished component prepared for another production cycle.

Industrial Roll & Cylinder Coatings

Surface engineering according to the application
Different roll positions require different surface characteristics.

A surface designed for high wear resistance may not provide the release or grip required in another application. Coating selection should therefore begin with the function of the component, not simply with the coating technology.

PR Rolls provides functional metallic coatings for both new and existing industrial rolls and cylinders.

Depending on the application, required properties can include:

• Wear resistance
• Corrosion protection
• Release properties
• Non-stick characteristics
• Grip and traction
• Controlled roughness
• Resistance to contamination
• Surface durability

The coating should not be considered simply as a protective layer.

It is the functional interface between the roll and the production process.

By combining coating expertise with grinding and precision finishing, PR Rolls can control both the coating and the final functional surface within the same workshop project.

Roll Grinding & Precision Surface Finishing

Restore geometry and create the required final surface
Industrial rolls can gradually develop changes in geometry and surface condition during operation.

Typical conditions include:

• Uneven wear
• Diameter variations
• Scratches
• Grooves
• Corrosion
• Surface damage
• Profile deviations
• Deteriorated surface finish

PR Rolls provides workshop grinding and precision surface finishing to restore the required geometry and surface characteristics.

Grinding can be performed as an individual maintenance service or integrated with coating and refurbishment.

For an existing roll:

Measurement → Grinding → Surface restoration → Coating → Precision finishing

For a newly manufactured roll:

Surface preparation → Coating → Grinding / Precision finishing → Verification

The goal is not simply to produce a visually smooth surface.

The goal is to achieve the geometry and surface functionality required by the application.
