These rolls are manufactured by using flap elements of non-woven abrasive materials radially glued around a central fibre core.

It is also possible to make a particular impregnation treatment by the use of a mixture of chemical resins that weld the single flaps to each other.

This impregnation allows to obtain a more compact roll which increases performance, efficiency, life and uniformity for wider adaptability to the different work processes.

This type of impregnation improves the performance of the roll and its possible to use the rolls during different step of the work.
