Abstract
An apparatus for transporting a tail end in a fiber web machine from one structural section to another includes nozzles for guiding the tail end on the guide plate by means of an air flow such that the blown air is brought onto a guide plate shaped into a curve in such a way that the air flow of the blown air guides the tail end onto the curved guide plate by means of a bump functioning as an aerodynamic profile formed in the curved guide plate.
Claims20
An apparatus for transporting a tail end in a fiber web machine from one structural section to another, the apparatus comprising:
- one or more nozzles formed on a surface of a nozzle frame and configured to direct blown air, the directed blown air defining an air flow for transporting the tail end in a controlled fashion in a direction parallel to the air flow, the one or more nozzles receded obliquely from the surface of the nozzle frame;
- and
- a guide plate coupled directly to the nozzle frame and having a streamlined surface configured to guide the air flow along the streamlined surface, the one or more nozzles configured to direct the blown air onto the streamlined surface, the streamlined surface including a bump and a surface portion located downstream from the bump with respect to the air flow.
A guidance system for transporting a tail end in a fiber web machine from one structural section to another, the guidance system comprising:
- a plurality of nozzle frames, each nozzle frame having a respective one or more nozzles formed on a surface of the respective nozzle frame and configured to direct blown air, the directed blown air defining an air flow for transporting the tail end, the one or more nozzles receded obliquely from the surface of the respective nozzle frame;
- and
- a plurality of guide plates, each guide plate coupled directly to a respective nozzle frame, at least one guide plate among the plurality of guide plates being coupled to a respective nozzle frame and another nozzle frame located downstream from the respective nozzle frame with respect to the air flow, each guide plate having a respective streamlined surface, each streamline surface including a bump and a surface portion located downstream from the bump with respect to the air flow.
A method for transporting a tail end in a fiber web machine from one structural section to another, the method comprising:
- directing blown air from a nozzle formed on a surface of a nozzle frame onto a guide plate coupled to the nozzle frame, the one or more nozzles receded obliquely from the surface of the nozzle frame, the directed blown air defining an air flow for transporting the tail end in a controlled fashion in a direction parallel to the air flow, the guide plate having a streamlined surface configured to guide the air flow along the streamlined surface, the streamlined surface including a bump and surface portion located downstream from the bump with respect to the air flow.
