ABSTRACT:
In a floating type web guiding device in which a moving web is guided along a guide surface with fluid jetting holes while being floated above the guide surface, two groups of flow straightening boards are provided respectively at the web lead-in part and the web lead-out part of the guide surface in such a manner that the boards are arranged in parallel with the direction of movement of the web and perpendicular to the web surface, so that the web can be conveyed without rubbing the web surface.
