Abstract (en)
[origin: WO9847697A1] Method and apparatus are disclosed for embossing paper webs (200) using opposing embossing and imprinting rolls (500, 502). In the preferred embodiment, the embossing roll (500) and the imprinting roll (502) have differing diametrical dimensions, thereby producing differing velocities through the nip, causing the embossing projections (104), of the embossing roll (500) to sweep through modified imprint cells (120) of the imprint roll (502), thereby affecting an automatic sweeping of accumulated debris (170) from the imprinting cell (120) as the embossing operation takes place.
