Abstract
Method for conveying strip materials in a floated manner whereby a strip is allowed to pass between a pair of chambers vertically spaced apart from each other and provided with a plurality of jets or blow-off openings at one surface thereof so that jets of gases are blown therefrom against the strip so as to float the strip. If the strip to be conveyed is of a smaller width, then the width of gases blown from the lower chamber are correspondingly reduced so that a saving of energy required for blowing the gases may be achieved.
Claims6
A method for conveying strip materials while floating the strip by blowing jets of gases against the strip from a pair of chambers vertically separated from each other with a strip-conveyance passage disposed therebetween, including the steps of:
- a. adjusting the width of blowoff of gas from the lower one of said chambers in accordance with the particular width of the strip to be conveyed;
- and
- b. controlling the rate of supply of gas to said lower chamber so that the speed of gas blown against the strip with said adjusted blowoff width is set at such a value as allows the strip to be floated in a steady manner.

- a. adjusting the width of blowoff of gas from the lower of said chambers in accordance with the particular width of the strip to be conveyed;
- and
- b. discharging a portion of the gas supplied into said lower chamber from outside said adjusted blowoff width so that the speed of the gas blown against the strip from said adjusted blowoff width is set at such a value as allows the strip to be floated in a steady manner.
