Abstract
A metal strip is supported under static gas pressure by using an apparatus which comprises a pair of gas pressure pads facing each other and located symmetrically about a predetermined moving path of the metal strip, each gas pressure pad having an opening through which a gas is ejected toward the moving path of the metal strip, and means for supplying a gas under pressure to each of the gas pressure pads, each opening being in the form of a closed channel which is composed of a pair of lateral slits, each lateral slit extending in the lateral direction of the moving path of the metal strip, and two or more pairs of longitudinal slits, each longitudinal slit extending in an inclined direction to the longitudinal direction of the moving path, and connecting therethrough to each of the lateral slits, the opening being formed symmetrically about a longitudinal center line of the front surface of the gas pressure pad, drawn parallel to the longitudinal axis of the moving path.
