Thanks a lot! This is the clue I needed. At least I am able to typeset the landscape pages and can have following pages in portrait again!
----------
This example will float the table to the centre of the page, if you'd like to anchor the float to the bottom of the page, you make have to get out the \frame{} toolkit.
How do I setup a correct switching [for this type of structure]?
\chapter{One}
running tex A4
\chapter{Two}
landscape table A4
\chapter{Three}
running text A4
You want rotated chapter headings, headers and footers, etc., I've never done that.
Basically I think, that it could be a good idea, to have a heder beeing rotatet with the content of the page. Sofar one can include the \chapter[]{} in the \rotate[]{} command and it is nicely rotated with the rest of the page. I will try further.... Thanks for your example! Willi
