First Claim
1. An apparatus for producing a fibrous web, the fibrous web being a tissue web, the apparatus comprising:
- a circulating permeable structured belt;
a circulating non-structured supporting belt, the fibrous web passing in lying position between said circulating structured belt and said circulating non-structured supporting belt in a press zone;
a supporting surface having a substantially smooth surface; and
a Yankee cylinder having a press nip through which the fibrous web is passed in lying position together with said circulating permeable structured belt, the fibrous web being between said circulating permeable structured belt and said Yankee cylinder, said press zone being limited on a side adjacent said supporting belt by said substantially smooth surface, said circulating non-structured supporting belt not being brought together with the fibrous web and said circulating structured belt until being proximate to said press zone.

Abstract
An apparatus for producing a fibrous web, in particular a tissue web, with a press zone through which the fibrous web is passed in a lying position between a circulating permeable structured belt and a circulating permeable non-structured supporting belt. A press nip is provided on a Yankee Cylinder through which the fibrous web is passed in the lying position together with the structured belt between the structured belt and the Yankee cylinder, whereby the press zone is limited on the side adjacent the supporting belt by a substantially smooth surface, and whereby the supporting belt is not brought together with the fibrous web and the structured belt until proximate to the press zone.

26. An apparatus for producing a fibrous web, the fibrous web being a tissue web, the apparatus comprising:
-
a circulating permeable structured belt; a circulating non-structured supporting belt, the fibrous web passing in lying position between said circulating structured belt and said circulating non-structured supporting belt in a press zone; a deflecting roller; a supporting surface having a substantially smooth surface; and a Yankee cylinder having a press nip through which the fibrous web is passed in lying position together with said circulating permeable structured belt, the fibrous web being between said circulating permeable structured belt and said Yankee cylinder, said press zone being limited on a side adjacent said supporting belt by said substantially smooth surface, said circulating non-structured supporting belt being brought together with the fibrous web and said circulating structured belt, said supporting belt being brought together with the fibrous web and said permeable structured belt proximate to said deflecting roller preceding said press zone in a web running direction, said structured belt, the fibrous web and said supporting belt jointly enwrapping said deflecting roller over a wrap angle, said wrap angle being less than approximately 45 degrees.
