Endless and seamless attribute conveyor felt roll tube without joints and seams. It has no weaknesses and has a flat thickness.

The aluminum extrusion roller is flat with no blemishes, bumps, scales. The surface is extremely smooth. Will not contaminate aluminum. especially suitable for the production of aluminum products with extremely high requirements for electrophoretic surfaces and polished surfaces.

The felt material is 100% pure, without any impurities, the higher the purity, the higher the quality, the heat-resistant temperature meets the requirements, the abrasion resistance, and the effective use time is longer than other manufacturers.


PBO Seamless Felt Roller is initial Table before Interrupt saw and Forepart of Run-out Table after Interrupt saw in aluminum handling system, the PBO Tube used at the outlet or slide-out table in aluminum profile extrusion.  Felt Roller for aluminum extrusion


How to make PBO Felt Roller

PBO fiber

PBO material is prepared by solution polycondensation of 4,6-diaminophenol hydrochloride and terephthalic acid with polyphosphoric acid as solvent. It is a reinforcing material for composite materials developed by the United States in the 1980s for the development of the aerospace industry.
The strength is 5.8GPa, the modulus is 280GPa, which is the highest among the existing chemical fibers; the heat resistance temperature reaches 600℃, the limiting oxygen index is 68, it does not burn or shrink in the flame, and the heat resistance and flame resistance are higher than any other An organic fiber. Mainly used in heat-resistant industrial textiles and fiber-reinforced materials.

PBO material


Carding machine opens and combs heat resistant fibers to remove impurities.
The curled or lumpy fiber mass will become a state of a straight single fiber.
And At the same time, in the ginning process, it can remove the impurities and short lint in the fibers.
Ensuring the uniformity of the warp and weft tensile, length, and number of yarns in the base fabrics, under strictly controlled temperature and humidity conditions.
In the final stage of carding, the needle machine will punch the pure PBO fibers to become the temperature resistant felt layer.

How to make high temperature felt

Weaving Laying

The fiber enters the web-laying machine, takes an approach to automation using robots, ensures consistent high quality and productivity.
The web-laying trolley is driven by a toothed belt to cross-fold the PBO fiber single web output from the carding machine.
Our weaving employs sophisticated tension management technologies to make it into a multi-layer web with the required width and unit weight.

High temperature felt manufacturer


Full resin or semi-resin treatments are available to improve the wear resistance and durability of the PBO & Kevlar roller cover. It also prevents aluminum swarf or dirt from sticking to the aramid felt, reducing damage to the surface of aluminum profiles.

Felt manufacturing process


The PBO heat resistant roller is cut with an electric rotating fabric cutting machine. Whether in terms of specifications or quality, Pure® felt tubes can perfectly meet customer needs. Using superb technology and machinery, cut out the size required by the customer, and cut out the edge-free felt roller.

All the finished products will be inspected by our professional-quality control staff with metal detector equipment, to ensure all products are inspected and there are no broken needles inside the PBO and kevlar roller covers. Foshan Pure technology always insists that we’ll only deliver the goods to our customers after our products pass a series of rigorous tests.

Frequently Asked Questions

Q: What information do I need to provide?
A: Need to provide felt rollers size, machine model and picture, delivery address, and zip code to calculate shipping

Q: What is the process of placing an order?
A: Contact us for PBO needled felt roller size and quotation, We provide you with an invoice-remit the money to the bank account-arrange the heat resistant felt production after receiving the payment-settle the balance before shipment- send out the felt rollers – receive the goods

Q: Are there any additional costs?
A: Additional taxes and fees are determined by your local customs duties

Q: Where is the origin of the fiber?
A: The low-temperature fiber polyester has a temperature resistance of 180 degrees and is produced in Yantai, China.
Nomex, a medium-temperature fiber with a temperature resistance of 280 degrees, comes from the USA.
The high-temperature fiber Kevlar has a temperature resistance of 480 degrees and is produced in the USA.
The PBO fiber has a temperature resistance of 600 degrees and the place of origin comes from Japan.

Q: Is it normal for the PBO roller sleeve to become black after only a few days of use? What caused it?
A: It is not in the normal range. It means that the felt drum is not rotating properly. After the PBO and Kevlar felt roller sleeve is rotated by hand, it only rotates one or two times, which will cause the PBO felt tube to turn black in a few days. It is an abnormal use condition and must be guaranteed to rotate seven It takes eight turns for normal use.
