CALM has been supplying conveyor roller covers to the aluminum extrusion industry for many years. Each conveyor roller sleeve is made-to-order based on customer needs to ensure the machine can run properly.

 

We offer a wide range of industrial felt materials to choose from. The four heat resistant felts - PBO, Kevlar, Nomex, and Polyester - are available for different temperature zones during extrusion. Besides, resin treatment can be applied on request to improve durability.

               Conveyor Felt Roller

 
 
 
How the Industrial Felt Roller Cover Is Made
 
 

 

How to produce the PBO + Kevlar roller cover? The needle machine punches the PBO felt layer on the Kevlar roller cover base. And needles punch around the correct mould and make the precise size of the industrial felt roller.

 

 

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

 

 

This is the manufacturing of PBO + Kevlar roller cover 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: 
Each of our 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 conveyor roller sleeve can install on existing conveyor system perfectly without any deviation.
 
 Made-to-order: 
Four industrial grade felts are available to meet customer needs, and we can process the industrial felt roller into pure or blend structure in a reasonable ratio.
 
  Smooth felt surface:
With the needle punched technique, the surface of conveyor felt sleeves is smooth with no woven pattern, providing better protection to aluminum profiles.
 
 100% pure felt: 
Advanced inspection equipment ensures the heat resistant felt cover has no residue of broken needles or hidden impurities. So it won’t leave any stains and dents on aluminum profiles.
 
 New-tech fiber: 
Compared to traditional material graphite, industrial felt roller features excellent heat resistance with a soft touch. It does not easily scratch or leaves marks on the surface of aluminum extrusions as graphite does.

 High strength: 
The high-quality conveyor roller sleeve has a thick fiber layer with high density. With a strength of 5.8 GPa and a modulus of 280 GPa, PBO fibers are the highest among the existing chemical fibers, far exceeding steel and carbon fibers.  
 
 Resin hardening:
Full resin or semi-resin treatments are available to improve the wear resistance and durability of the conveyor roller cover. It also prevents aluminum swarf or dirt from sticking to the felt, reducing damage to the surface of aluminum profiles.

FAQ
 

  • Q How many kinds of felt rollers does Calm offer?

    A
    4 industrial felt in different heat resistances to choose from - PBO (600℃), Kevlar (480℃), Nomex (280℃), and Polyester (180℃).
    We can also produce a blend structure with two different felts in a workable way according to your needs.
  • Q What is the function of felt roller sleeve?

    A Aluminum profiles fresh from the extruder are soft and hot. And the industrial conveyor roller cover has excellent heat resistance, which is a vital conveyor part to protect the surface of aluminum extrusion.
  • Q What is the superiority of calm conveyor felt cover?

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

    A Take PBO + Kevlar conveyor roller cover as an example. Our production standard is 3mm PBO layer + 7mm Kevlar layer. 
    And you can also customize the fiber layer in 4mm, 5mm, or any other thickness you want.
    By the way, the thicker the PBO layer, the more durable it is, but the more it costs. It all depends on your needs and budget.
