Abstract: PURPOSE:To improve the floating passing performance on plate by installing weir-shaped side guides at the edge parts in the direction of width on a fluid supporting pad surface having a fluid blow-out port and eliminating the deflection from the center part of a band-shaped article. CONSTITUTION:Weirs 3 are installed at the both edges in the direction of width of a pad 2 for fluid floating-up having a fluid blow-out port. A band-shaped article 1 which passes in floating-up on a pad 3 by the blow-out of the fluid is deflected from the center part and set to the R side of the weir 3, the interval between the band-shaped article 1 and a side guide wall 3 reduces, and almost all the fluid supplied from the fluid blow-out port is allowed to flow from the R side to the L side on the undersurface of the band-shaped article 1. Therefore, the deflection from the center part in the direction of width of the band-shaped article 1 is automatically corrected, and the article 1 is allowed to pass always in stable state on the plate at the center part, and the on-plate passing performance can be improved.
