Abstract (en)

[origin: WO2009138067A1] A device (10) for folding a paper web (28) comprises a pair of tool shafts (24, 26) carrying circular blades (70, 74) which pair is arranged upstream or downstream of its folding rollers (16, 18, 20, 22). The circular blades (70, 74) and/or the transport roller units (40, 50) can be rotatively driven for transporting the paper web at the same web running speed in the region of the tool shafts (24, 26) and in that of the folding rollers in such a manner that the speed components of the circular blades (70, 74) in the web running direction are at least not lower, preferably higher than the web running speed of the paper web (28).
