The invention relates, according to a first aspect, to a press (10; 110) for the press section of a papermaking machine. The press is of the type having a rotary press roll (12; 112), a substantially stationary pressure shoe (14; 114), and a press belt (18; 118) running in an endless path around the pressure shoe between this and the press roll and having a substantially impermeable inner surface facing the pressure shoe. A separate, endless reinforcing belt (30; 130) enclosing the press belt (18; 118) is in frictional engagement over the entire length of the press belt so as to run together with the press belt in the endless path. The reinforcing belt (30; 130) may be presstressed, e.g. by shrinkage, in its running direction and, optionally, also transversally thereof. According to a second aspect, the invention relates to a method of modifying a press (10; 110) of the type indicated above, in which method the press belt (18; 118) is enclosed by a separate, endless reinforcing belt (30; 130) of the above-indicated type. |
