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.
SPECIFICATIONS Working Temp
Inner diameter (ID): 41mm - 127mm PBO - 600℃
Thickness: 5mm - 14mm Kevlar - 480℃
Length: Custom made Nomex - 280℃
Polyester - 180℃
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.
