Abstract
The invention relates to a device and a method for manipulating a fibrous web (). The device comprises at least one blower (A,B) provided with a flow-preventing element (A,B) which is arranged to produce at least one blow (A,B) substantially in the direction of the fibrous web (), and a friction element () against which the fibrous web () is arranged to be pressed at least partially from the effect of said blow (A,B) and flow-preventing element (A,B) to apply a friction force resisting the motion of the fibrous web () to the fibrous web (). According to the invention, the blow (A,B) is directed substantially away from the friction element () and the friction element () comprises a surface profile which is arranged such that, from the effect of said at least one blow (A,B), a continuous vacuum is created on the surface of the fibrous web () on the side of the friction element (). Due to its intensified friction effect, the device according to the invention is applicable especially for board and, by means of it, it is possible to form e.g. an air cutting device in the tail-threading section of a board machine.
