details of this appealed subject matter are recited in
representative claims 1 and 11, the only independent claims on
appeal, reproduced below:
1. A press section of a machine for producing a
fiber material web comprising:
at least two double-felted presses arranged in
series in a travel direction of the fiber material
web;
an upstream one of the at least two double-felted
presses comprising a deflection-controlled shoe press
roll and a suction roll; and
the deflection-controlled shoe press roll and
suction roll being arranged to form the upstream press
nip, and the suction roll having a suction zone
arranged to extend, in a downstream direction, beyond
the upstream press nip; and
the web and one of the felts of the upstream
double-felted press being guided around the suction
roll and over the suction region downstream of the
upstream press nip.
11. A process of guiding a fiber material web
through a press section of a web producing machine
that includes at least two double-felted presses
arranged in series in a travel direction of the fiber
material web, the process comprising:
guiding the fiber material web through a press
nip of an upstream one of the at least two double-
felted presses formed by a deflection-controlled shoe
press roll and a suction roll, wherein the suction
roll has a suction zone arranged to extend, in a
