At PROEXPORT, we manufacture new paper rewinder rolls and refurbish worn work rolls for rewinders, slitter rewinders and paper converting lines. Before selecting a coating, we check whether the problem stems from the surface, geometry, runout, journals, bearing seats or operating conditions.
manufacturing new rolls from technical documentation or a physical sample,
refurbishment of the working surface, journals and mechanical components,
coating selection: hard chrome plating or a ceramic coating for more severe abrasive wear.
Please submit a drawing, photos, basic dimensions, or a description of the roller's operation.
At PROEXPORT, you can order both new paper-rewinding rollers and have worn-out work rollers reconditioned. We tailor the scope of work to the documentation, the condition of the surface, the journals, the geometry, and the operating conditions of the roller on the production line.
We manufacture new paper-rewinding rollers in accordance with the customer's technical documentation or based on a provided sample.
We refurbish worn rollers, with our work covering the working surface, pins, bearing seats, and components requiring repair.
We apply hard chrome plating to the working surface and carry out the subsequent finishing operations when required by the application and the condition of the roll.
After applying the coating or repairing the working surface, we can perform grinding, polishing and, if required, honing.
As part of refurbishment, we can inspect, repair or rework the journals and bearing seats.
Once the agreed-upon work is complete, the roller can undergo quality control and dynamic balancing before being prepared for installation.
For the evaluation, please prepare a drawing, photos, basic dimensions, or a description of how the roller works in the machine.
We manufacture or recondition paper rewinding rollers based on documentation, a sample, or an assessment of the worn component. We select the specifications based on the roller’s function in a rewinder, winder, or packaging line.

Paper rewinding rollers are used wherever material is fed, rewound, or packaged from a roll. In every application, the condition of the working surface, the geometry, the runout, and the mechanical components of the roller are important.
In paper mills, rollers operate under conditions where stable web guidance, surface wear resistance, and the mechanical condition of the component are critical.
In rewinders and bobbin winders, the roll works directly with the material. The working surface, geometry and bearing arrangement affect how the paper web is guided.
When rewinding from larger reels to smaller ones, common indicators for evaluating the roller include slippage, surface wear, runout, or bearing problems.
In the production of paper bags, the stable operation of the guide or working rollers is important when wear, runout, or a mechanical problem hinders the feeding of the material.
The paper rewinding roller affects web guidance, the stability of the rewinder’s operation, and the number of adjustments made by the operator. It is not only the coating that matters, but also the geometry, runout, journals, and the condition of the bearing seats.
Proper roller geometry and a properly prepared working surface help reduce paper feed problems during rewinding.
A worn, dirty, or improperly selected surface can increase the risk of the web slipping. Therefore, it is worth checking whether the cause lies with the roller or with the line settings.
When the roller has stable geometry and a properly prepared surface, the operator does not need to compensate for problems resulting from wear on the component.
Wobble, worn bearing seats, or damaged journal shafts can affect the operation of the line even if the working surface itself has been refurbished.
Paper slippage, uneven winding, or vibrations are not always caused by the coating itself. The cause may also be runout, geometry, bearings, pressure, tension, or line settings.
The reconditioning of a paper-rewinding roller involves more than just restoring the working surface. At PROEXPORT, we analyze the entire component: the coating, the journals, bearing seats, geometry, runout, and the scope of machining required to prepare the roller for further operation.
We inspect the working surface, visible damage, journal shafts, bearing seats, geometry, runout, and information about the current coating.
Depending on the degree of wear, we can inspect, repair, or prepare the journal shafts and the areas where they interface with the bearings.
We evaluate the bearing seats and components that affect roller installation, operational stability, vibrations, and the risk of the problem recurring after reconditioning.
If the condition of the roll allows refurbishment, the surface can be prepared and the working-surface coating restored in accordance with the agreed scope of work.
After restoring the surface, we perform finishing operations, including grinding, polishing, and—if necessary—honing.
Once the agreed-upon work is complete, the roller can undergo quality control and dynamic balancing before being prepared for installation.
Send us photos, a technical drawing or a description of the problem, and we will assess the feasible scope of refurbishment.
When a paper-rewinding roller is worn out, the most important thing is to determine whether the component is suitable for reconditioning or whether it would be better to manufacture a new roller. At PROEXPORT, we first analyze the technical condition and only then recommend the scope of work.
In the absence of a technical drawing, we can assess the feasibility of the application based on a physical model. The final decision depends on the condition of the roller, its geometry, surface wear, the roller pins, and the bearing seats.
The production or refurbishment of a paper-rewinding roller begins with an analysis of the available data: drawings, photos, dimensions, a description of the problem, or a physical sample. Based on this, we determine the possible scope of work and the approach to be taken.
Please send a technical drawing, photos of the roller, basic dimensions, a description of the problem, or information about how the roller operates in the machine.
We check whether the problem might be caused by the working surface, geometry, runout, journal pins, bearing seats, or operating conditions.
We determine whether the appropriate approach is refurbishment, manufacturing a new roll, hard chrome plating, a ceramic coating or additional mechanical work.
We prepare a quote based on the agreed-upon scope of work: manufacturing, remanufacturing, coating restoration, machining, or work on metal parts.
We perform the agreed-upon work: surface preparation, chrome plating, machining, mechanical repairs, polishing, honing, or balancing.
Once the work is complete, the roller undergoes an agreed-upon quality inspection, and is then prepared for transport and installation at the customer's site.
For an initial assessment, a drawing, photos, basic dimensions, or a description of the roller's operation are sufficient.
For paper rewinder rolls, the coating is only one part of the assessment. Before preparing a quotation, we analyse the roll’s function, working-surface condition, geometry, runout, journals and bearing seats. This allows the scope of work to be based on the actual problem rather than an arbitrary choice of solution.
First, we check whether the problem might be caused by the coating, runout, geometry, pins, bearings, or operating conditions on the production line.
Reconditioning may involve not only the working surface, but also work on the journal bearings, bearing seats, geometry, and balancing.
We treat technical chrome as the standard material for many work rolls. We consider ceramics when operating conditions call for higher wear resistance.
After the agreed-upon work has been completed, the scope of inspection may include, among other things, measurement of surface roughness, coating thickness, or dynamic balancing.
Please submit photos, a technical drawing, basic dimensions, or a description of the roller’s operation. Based on this information, we will assess whether the best course of action is reconditioning, a new roller, technical chrome plating, ceramic coating, or work on the metal component.
When manufacturing or refurbishing paper-rewinding rolls, it is usually necessary to determine the roll’s function in the line, surface condition, type of coating, runout, geometry, journals, and bearing seats.
Selecting a paper rewinder roll begins with understanding its function in the line. A guide roll is assessed differently from a working roll, and both differ from a component operating in an area exposed to slippage, abrasive wear, runout or bearing-related problems.
In the initial assessment, it is important to determine whether the roller is used in a rewinder, a winder, a paper mill, or a paper packaging line. It is necessary to establish whether its function is to guide the web, stabilize the material’s movement, to make contact with the paper under pressure, or to operate in a location where slip or uneven winding occurs.
A worn, damaged, or dirty surface can affect the contact between the roller and the paper. Therefore, before selecting a coating, we check whether the problem is related to the surface itself or stems from other factors: runout, geometry, contact pressure, tension, or line settings.
Hard chrome plating is a standard option for many work rolls and provides a hard, functional surface that can be refurbished again. A ceramic coating may be suitable for more severe, uniform abrasive wear, but it is not automatically the better solution for every application.
Even a well-chosen coating won’t solve the problem if the roller has damaged pins, worn bearing seats, excessive runout, or alignment issues. That’s why, during reconditioning, we analyze the entire component, not just the working surface.
