摘要
A calendering roller used to manufacture textured nonwoven fabric comprising papermaking fibers (46), the calendering roller (40) comprising a positive pattern (10) that comprises: - a basic element (11) having a ring shape, the ring (12) defining an apex relatively to a center portion of the ring (12) defining a cavity (14) and a grinded surrounding zone (15), the ring (12) comprising at least one radial channel (16) putting in communication the cavity (14) and the grinded surrounding zone (15) so as to define a discontinuous calendering surface (13); and - a repetition of said basic element along multiple rows (20) and columns (21) substantially overall a peripheral surface of the calendering roller (40), the repetition being regular except for multiple substantially longitudinally (22) and transversally (23) oriented regions, said regions (22, 23) being of limited size with respect to a calendering roller size and randomly distributed so as to define multiple random longitudinal and transverse lines (62, 63) in the textured nonwoven fabric comprising papermaking fibers (46), generating a cloth-like visual texture.
