Title: PRESSING ROLLER FOR THE PROCESSING OF WEB PAPER MATERIAL
Abstract:
A pressing roller (10) for the processing of web paper material, in particular of the type used in cooperation with an engraving roller (G1) for the bonding of two or more embossed plies of web paper material, comprises a cylindrical pressure surface (1 1) defined by a plurality of annular resilient pressure bodies (15) of rubber material that have a high surface hardness which allows to avoid the effect of "double embossing" and at the same time have a high elastic yielding which allows to obtain adequate nip also with relatively low contact pressures.
