Abstract
A calendering roller used to manufacture textured nonwoven fabric including papermaking fibers is disclosed. The calendering roller includes a positive pattern that includes a basic element having a ring shape and a repetition of said basic element along multiple rows and columns substantially overall a peripheral surface of the calendaring roller. The ring defines an apex relatively to a center portion of the ring defining a cavity and a grinded surrounding zone. The ring includes at least one radial channel putting in communication the cavity and the grinded surrounding zone so as to define a discontinuous calendering surface. The repetition is regular except for multiple substantially longitudinally and transversally oriented regions. The regions are of limited size with respect to a calendering roller size and randomly distributed so as to define multiple random longitudinal and transverse lines in the textured nonwoven fabric including papermaking fibers, generating a cloth-like visual texture.
