Abstract

Turning device for a sheet material for drying, and other paper, cellulose, and the like treatments, comprising an air distribution duct connected to an air supply device, characterized in that the duct has a cross section substantially semicircular, and because the arcuate portion of the surface thereof oriented towards the rotating sheet is perforated, and also because the conduit is provided, on each side of said perforated portion, with a longitudinal groove with a shape such that the air projected to the outside, form a curtain directed towards the sheet, thus opening a space between the sheet, and the duct in order to maintain sufficient static overpressure within said space to rotate the sheet around the duct without friction.
