ABSTRACT:
Apparatus for conveying strip materials while floating them whereby a strip is allowed to pass between a pair of plenum chambers vertically spaced apart from each other and provided with blowoff openings through which gases are blown against the strip to float it as well as heat or cool the same. After the gases have been blown against the strip, a portion of them streams in one direction crossing the predetermined conveyance course of the strip, while the other portion thereof streams in the opposite direction. A pair of flow-rate control means are provided in conjunction with the plenum chambers and in opposite positions so as to vary the amount of gases streaming in said one direction in relation to that of those streaming in the other direction, when the strip has taken a winding course during conveyance, so that the strip is restored to its predetermined course of conveyance.
