Film and sheet processing
Often used before coating, laminating, slitting, or rewinding, where loose particles may later become visible defects inside the product.
Custom Cleaning and Sticky Rollers
Cleaning rollers, dust removal rollers, and sticky rollers are used to remove dust, fibers, powder, fine particles, and other loose surface contamination before the next process turns them into visible defects.
They are commonly used on film, foil, paper, nonwoven, sheet, and other web materials before coating, laminating, printing, slitting, rewinding, or other surface-sensitive steps.
What matters is not only whether the roller feels sticky. The real question is whether it can remove loose contamination at that position without causing new problems such as marks, unstable contact, material pickup, or secondary transfer.
Wolorin can review and customize cleaning rollers, sticky rollers, and related contact-cleaning roller structures based on an existing roller, drawing, sample, installation space, line condition, or current contamination problem.

Typical Problems These Rollers Are Used to Reduce
These rollers are usually reviewed when the line is still running, but surface cleanliness is no longer stable enough for the next process.
Typical situations include:
- Loose dust or fine particles before coating or laminating
- Fibers or paper dust entering a printing contact area
- Particles becoming trapped during winding or rewinding
- Small contamination causing visible spots, bubbles, or raised defects after coating
- Sensitive film or foil surfaces picking up loose foreign matter before contact
- Static-attracted dust returning to the web again after a normal cleaning pass
- Loose fibers, powder, or attachments on nonwoven or similarly dusty materials
These rollers are most useful when the contamination is still loose enough to be picked up. If the problem is already adhesive buildup, ink residue, glazing, resin deposit, or film-like transfer on the roller surface, the review direction may no longer be only dust removal.
Where Cleaning and Sticky Rollers Are Usually Used
Protective film and release film lines
Often reviewed where small contamination can be trapped during contact-sensitive lamination or winding.
Printing and label lines
Often used to reduce paper dust, fibers, and loose particles before the web enters a printing contact position.
Coating and laminating lines
Usually reviewed where the next process can easily turn loose contamination into coating spots, bubbles, or surface defects.
Nonwoven lines
Often used where the material surface carries fibers, powder, dust, or loose attachments and the contamination behavior is not fully stable.
Paper and board converting
Often used to reduce edge dust, paper dust, and loose contaminants before converting, coating, printing, or winding.
Foil and other sensitive web materials
Often reviewed where surface marks, trapped particles, and contamination inside the final roll are more difficult to accept.
On thin web lines such as Film Converting Rollers or more sensitive positions such as Lithium Battery Line Rollers, cleaning performance usually depends not only on tackiness, but also on shedding control, contact stability, surface protection, and how the contamination is removed from the roller.
What Affects the Cleaning Result
The result does not depend only on how sticky the roller surface is. In most cases, the key factors are contamination type, material surface, contact pressure, line speed, and how the collected contamination is removed from the roller.
Contamination Type
Loose dry particles, dust, fibers, paper dust, powder, and static-attracted particles may require different surface directions. If the problem is adhesive residue, ink residue, resin buildup, glazing, or film-like contamination on the roller, it should be reviewed as a surface condition or release problem, not only as dust removal.
Material Surface Sensitivity
Film, optical film, release film, protective film, foil, nonwoven, paper, and coated materials react differently to tackiness and pressure. The roller needs enough contact to pick up contaminants, but not so much that it creates marks, dents, pulling, scratches, or adhesive transfer.
Tackiness, Hardness, and Pressure
Too little tackiness may leave particles on the material. Too much tackiness may pull the web, pick up material, leave marks, or make the roller dirty too quickly. Contact pressure should also be controlled. Too little pressure may cause unstable contact; too much pressure may press particles into the material surface.
Contamination Transfer and Maintenance
Many contact cleaning systems use an elastomer cleaning roller together with an adhesive roll, adhesive paper, cleaning pad, or contamination trap roll. If the collected contamination stays on the roller surface, it may be transferred back to the material later and cause secondary contamination.
For dusty or fiber-heavy materials such as Nonwoven Processing Rollers, cleaning frequency and static behavior may matter as much as the base roller material itself.
How the Required Direction Changes by Position
The same cleaning roller logic should not be copied blindly from one position to another.
Before coating or laminating
The main concern is often loose contamination that later becomes coating spots, bubbles, or trapped defects.
Before printing contact
Paper dust, fibers, and loose particles may disturb print contact or transfer consistency.
Before winding or rewinding
Small particles may not look serious at first, but later become trapped inside the roll and show up as pressure points or contamination in the finished roll.
On sensitive film or foil surfaces
The roller must help remove loose contamination without leaving marks, pressure points, or new surface damage. In some positions, low-mark material directions such as liquid silicone rollers may also need review.
Where static keeps pulling dust back
A normal sticky roller may remove some particles, but the result may still be unstable if the dust keeps returning because of static. In those cases, the position may also need review together with anti-static / conductive rubber rollers.
Reference Parameters for Cleaning Roller Selection
Exact specifications should be confirmed according to the roller position, material surface, contamination type, line speed, and installation space. The values below can be used as early review references, not fixed standards.
| Item | Review Direction |
|---|---|
| Hardness | Contact cleaning elastomers may use around 55 Shore A as a starting reference. Other positions may require different hardness according to contact pressure and material sensitivity. |
| Particle Control | Often reviewed for dust, fibers, powder, and loose particles. Some contact cleaning roller designs are used for unattached particles around the 1 μm level. |
| Line Speed | Contact web cleaning applications may involve reference running speeds around 250–400 m/min, depending on line structure, material behavior, and cleaning method. |
| Cleaning Width | Customized according to web width and installation space. Common review ranges may include 250–650 mm, 700–1300 mm, and widths up to 2500 mm for wider web applications. |
| Cleaning Method | Elastomer contact roller, sticky roller, adhesive roll, adhesive paper, cleaning pad, contamination trap roll, or similar cleaning structure. |
| Surface Requirement | Low shedding, non-scratching contact, stable running, controlled tackiness, and reduced secondary transfer risk. |
These values are not fixed specifications. For a real project, the roller should be reviewed together with the material surface, contamination type, line speed, installation space, contact condition, and maintenance method.
Common Material and Surface Directions
The material should be selected according to what the roller must do at that position.
Gentle surface cleaning
Silicone, soft elastomer, or another lower-damage contact surface may be reviewed
Sticky dust and loose particle pickup
Elastomer surfaces with controlled tackiness are often reviewed
High-speed film cleaning
Low-shedding, stable-contact surface direction is usually more important
Dusty nonwoven or fiber-heavy materials
Tackiness, cleaning frequency, and static behavior often need review together
Static-attracted contamination
Review together with anti-static / conductive rubber rollers where needed
Low-mark or more delicate surface contact
In some positions, liquid silicone rollers or other gentle-contact directions may be more suitable
Existing roller replacement
The old roller should be reviewed as a reference, not copied blindly by material name alone
When the Roller Should Be Reviewed Again
If your current cleaning roller has any of the following problems, it may not be enough to simply copy the old roller size:
- Dust or particles remain on the material after cleaning
- The roller surface quickly collects dust, buildup, glazing, or film-like residue
- New marks, pressure points, or scratches appear after the material passes the roller
- Cleaning performance drops after line speed increases
- Static attraction is obvious and a normal sticky roller does not work consistently
In these cases, the final solution may still follow the old roller, or it may require adjustment in material, hardness, tackiness, or surface design.
If the Problem May Belong to Another Roller Function
Not every contamination problem belongs to the cleaning roller itself.
Dust keeps returning because of static
Better review direction: anti-static / conductive rubber rollers
Problems around corona treatment, discharge, or insulation behavior
Better review direction: Corona Treatment Rollers
Web tracking, wandering, or unstable edge position
Better review direction: Guide Rollers
Uneven coating or unstable coating transfer
Better review direction: Coating and Laminating Line Rollers
Poor release, adhesive pickup, or material sticking
Better review direction: release or sticking review
Roller surface becomes glossy, builds up residue, or forms a film-like layer
Better review direction: roller surface condition review, not only particle pickup
This separation matters. Otherwise, a customer may keep replacing cleaning rollers while the main cause is actually somewhere else.
Custom Roller Manufacturing, Formulations, and Quality Control
A reliable rubber roller depends on more than size matching. Compound formulation, hardness stability, cover thickness, surface finish, shaft structure, and running accuracy all affect how the roller performs on your line.
Wolorin supports both routine replacement roller projects and more demanding custom industrial rubber roller projects, with established manufacturing experience, production equipment, inspection equipment, available certificates, and documented quality checks. Our rubber compound formulation system can be matched to different operating requirements.
Before shipment, key items such as cover hardness, shaft details, surface condition, and running accuracy can be checked according to project requirements.
You can review our manufacturing scope, quality control process, and company background through the pages below.
Frequently Asked Questions
No. If the roller is not tacky enough, particles may remain on the material. If it is too tacky, it may pull the material, pick up the web, leave marks, or become dirty too quickly. Tackiness, hardness, pressure, material surface, and maintenance method should be considered together.
Yes, if the old roller has been working well. You can send the old roller size, hardness, surface condition, and shaft details for replacement.
If the old roller already has poor cleaning performance, secondary transfer, buildup, marks, or short service life, it is better to review the working condition before deciding whether to adjust the material, hardness, tackiness, or surface direction.
Usually not. Film, foil, paper, coated surfaces, release materials, and nonwoven do not respond the same way to contact cleaning.
