ABSTRACT:
During the manufacture of a paper product such as paper or cardboard, a moving web of sheet material which is to form the paper product is lapped over a roll while the relatively smooth, hard surface of a smoothing member is pressed against an outer surface region of the sheet material across the entire width thereof while an inner surface region thereof engages the roll, so as to impart in this way desired characteristics to the surface of the web engaged by the smoothing member, with a frictional rubbing action being provided between the web and the surface of the smoothing member. The above roll may be the roll of a press section, a drying section, or a calendering section of a paper machine, and a suitable support structure carries the smoothing member to maintain the latter in engagement with the moving web. The smoothing member may be fixed to the supporting structure or may take the form of a smoothing roller supported for rotary movement by the supporting structure.
