1. A press for a paper machine with a smoothing press which is provided as a press at a final stage of a press section of a paper machine and functions to smooth a surface of a traveling wet web, said press comprising:
the smoothing press comprising:
an elastic member for guiding traveling of the wet web while retaining one face of the wet web;
a first press roll contacting with the other face of the wet web and having a surface formed from a rigid material; and
a second press roll having a surface formed from a rigid material for cooperating with said first press roll through said elastic member to generate a nip pressure to press the wet web;
a carrying belt provided on the upstream side of said first press roll and said second press roll for carrying the wet web from a final water-removing press of said press section to said elastic member; and
a pair of nip transfer rolls provided on the upstream side of said first press roll and said second press roll for generating, in a state wherein the wet web is held between said carrying belt and said elastic member, a nip pressure on the wet web; wherein
said elastic member is a paper feeding belt which does not have air permeability and whose hardness is set higher than that of said carrying belt.
