Construction

 

Roberto Nonwoven rolls are constructed from grooved high-grade steel centre shafts and steel end plates which retain a highly compressed micro-porous fibre cover of mixed fibres coated with a synthetic binder material. 

 

 

A range of Roberto materials is available to suit various steel and automotive industry applications.

 

Roberto roll covers are composed of a fibre based matrix with a porous surface and interior. The fibres are bonded together mechanically and by thermal and chemical treatment. The cover has about 40% void volume (small interconnected cavities) - see image above.

 

The resilience of the fibres and the elastic characteristics of the binding system ensure the porous/open structure has a high degree of flexibility, elasticity and strength.
