CALM offers conveyor roller covers for the aluminum extrusion industry. Each seamless felt roller is made-to-order to ensure the machine can run properly. 

We can produce different sizes of rollers according to customer requirements.

 

We also provide a wide range of materials for different temperature zones. The four high-performance fibers - PBO, Kevlar, Nomex, and Polyester, have different temperature resistance. In addition, resin treatment is available on request to improve durability.

FAQ

 
 

  • Q How many kinds of felt rollers do you offer?

    A
    We have 4 heat resistant fibers to choose from - PBO, Kevlar, Nomex, and Polyester. Also, according to your needs, we can produce a blend structure with two different felts in a workable way.
  • Q What is the function of felt roller sleeve?

    A
    As we all know, the aluminum profile fresh from the extruder is soft and hot. Therefore, in order to protect the surface of the extrusion, the conveyor roller cover made of heat resistant felt is necessary.
  • Q What is the superiority of your conveyor felt tube?

    A
    Traditional materials such as graphite have low buffering and easy to damage the profile surface with scratch marks. Ordinary felt roller is low strength and has poor resistance to high temperatures. And it's easy to get moldy inside, which leads to a short service life. In contrast, Calm heat resistant conveyor roller cover is more durable and efficient.
  • Q What is the blend structure of felt roller?

    A
    Take PBO + Kevlar felt tube as an example. Our production standard is 3mm PBO layer + 7mm Kevlar layer. However, you can also customize the fiber layer with 4mm, 5mm, or any other thickness you want. The thicker the PBO layer, the more durable it is, but the more it costs. All depends on your budgets and needs.

 

How to produce the PBO+Kevlar conveyor roller cover? The workers will put PBO and Kevlar fiber together into the needle machine. Then needles punch around the correct mould and make the precise size of the felt roller.

 

 

It shows the production process of the polyester conveyor roller sleeve. The needles punch the raw material around the roller mould. Finally, a heat resistant conveyor felt roller cover for the aluminum extrusion is completed.

 

 

This is the manufacturing of PBO+Kevlar felt tube that can resist 600℃ for the aluminum extrusion industry. PBO fiber goes around the roller mould, and needles punch to form a conveyor roller cover.

Advantages

 

 
 Endless & Seamless: 
Calm-brand round needled conveyor roller cover features no joints and seams. It has no weak points with highly uniform thickness.

 Accurate dimension: 
With the complete forming equipment, our heat resistant felt tubes can install on existing conveyor rollers prefectly without any deviation.
 
 Made-to-order: 
Depending on your budget, you can choose the synthetic fibers you need. And we can process the felt roller sleeve into pure or blend in a reasonable ratio.
 
  Smooth felt surface:
With the mature needle punched technique, the surface of felt roller cover is smooth with no woven pattern, which provides excellent protection to aluminum.
 
 100% pure felt: 
With advanced inspection equipment, we can make sure that our conveyor roller cover has no residue of broken needles or hidden impurities. So it won’t leave any stains and dents on the aluminum extrusion.
 
 New-tech fiber: 
Compared to traditional material graphite, heat resistant felt roller sleeve has a soft touch with excellent abrasion-resistant.  It does not easily scratch or leaves marks on the surface of aluminum profiles as graphite does.
 
 Resin hardening:
Full resin or semi-resin treatments are available to improve the wear resistance and durability of the felt roller cover. It also prevents aluminum swarf or dirt from sticking to the felt, reducing damage to the surface of the aluminum profile.
 
 High strength: 
The high-quality felt tube sleeve has a thick fiber layer with high density. PBO conveyor roller cover can be made not only from pure PBO fibers but also from PBO+Kevlar to save costs. CALM can also customize fiber layer thickness according to customer requirements.
