Abstract: PURPOSE: A belt and roll cover for use in papermaking, more particularly, a belt and roll cover for use in the press section of a papermaking machine that improves the smoothness and printability of the sheet surface are provided. CONSTITUTION: A press belt 12 is passing between the nip 14 formed between a first press roll 16 and second press roll 18. In the illustration, which is a double felted press, a press fabric 20 is shown on the lower portion thereof with the press belt 12 replacing the top press fabric normally used. This, of course, can be reversed as long as the press belt is placed on the side in contact with the sheet surface where smoothness and printability is required. Also, while a double felted press is shown, it should be understood that, in a conventional single-felted press (roll or shoe) a press belt run could be added so it again results in a configuration like Figure 1. Also the press roll cover can be replaced by the press belt instead of having an independent belt run. Where a loss in dewatering can be tolerated, it should be understood that, in a conventional single felt press (roll or shoe) the press fabric can be replaced by the press belt again, however, with the sheet being in contact with the press belt on the side where smoothness and printability is desired.
