Abstract

A machine for the production of a continuous web, particularly of paper or cardboard, may include a plurality of rolls around which a continuous web may be guided. The machine may also include a blocking device, arranged in a vicinity of an edge of the continuous web, to prevent turbulences and arranged at a predetermined distance from a free stretch formed by the continuous web traveling between two adjacent rolls. The blocking device may extend along a longitudinal portion of the free stretch, i.e, in a transport direction of the continuous web, and/or may extend across a portion of the free stretch transverse to the transport direction of the continuous web.
