Abstract
A calender for a sheet material, e.g., paper, having at least two treatment stations through which the sheet material passes in succession. To regulate a desired parameter of the sheet material, each treatment station may include a plurality of adjacently arranged adjustment zones positioned in a row extending across a width of the sheet material. The adjustment zones of one of the treatment stations are positioned to be offset relative to the adjustment zones of the other treatment station by a fraction of a width of the adjustment zones, e.g., one-half the width. The particular arrangement enabling improved correction potential without increasing structural expenditure.
