ABSTRACT:
A method and apparatus for inhibiting or preventing fluttering in a running paper web in a drying section of a paper machine, such as in the area of a twin-wire draw. Air jets are blown into pockets defined by a wire guide roll and wire itself, such air jets issuing from suitably designed and positioned blow boxes to be directed at the side of the wire supporting the web either in a direction towards or opposite from the running direction of the wire, and also at the side of the wire guide roll not supporting the wire, in a direction of the tangent of the guide roll. An air jet may also be blown into the pocket defined by the wire guide roll and the wire itself, at the side of the wire running free, not supporting any web, such air jet being directed substantially perpendicular to the wire. Fluttering of the paper web and drawbacks resulting from the same, such as wrinkles and breaks in the web, are inhibited or prevented.
