PCT No. PCT/SE92/00344 Sec. 371 Date Nov. 18, 1993 Sec. 102(e) Date Nov. 18, 1993 PCT Filed May 22, 1992 PCT Pub. No. WO92/20858 PCT Pub. Date Nov. 26, 1992.A press is devised for a papermaking machine. The press is of the type having a rotary press roll, a substantially stationary pressure shoe, and a press belt 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 enclosing the press belt is in frictional engagement over the entire length of the press belt so as to run together in the press belt in the endless path. The reinforcing belt may be prestressed, 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 of the type indicated above, in which method the press belt is enclosed by a separate, endless reinforcing belt of the above-indicated type. |
