摘要：
The uncoated side of a running web-shaped substrate, the other side of which carries a layer containing an evaporable solvent, is contacted by at least one idler guide roller which is rotated by the substrate. The angle of contact between the uncoated side of the substrate and the peripheral surface of the guide roller is increased by streams of compressed conditioning gas which is discharged by the orifices of two venturis one of which is located immediately upstream of the guide roller and directs gas counter to the direction of advancement of the substrate. The other venturi is located immediately downstream of the guide roller and its orifice discharges gas in the direction of advancement of the substrate.
