Abstract (en)

[origin: WO2023083509A1] The invention relates to a method for operating a production line (01) having a continuous dryer (17) for drying painted metal sheets (08), wherein: a loading station (02) which has a plurality of rotating wire frames (22) is located upstream of the continuous dryer (17) in the transport direction (T) of the metal sheets (08); each of these wire frames (22) uprights one of the metal sheets (08) which lie flat; in the transport plane of the metal sheets (08), the loading station (02) has a plurality of nozzles (14) out of which blown air is blown against the lower face of each metal sheet (08); at least one subset of the nozzles (14) are operated cyclically; these cyclically operated nozzles (14) are switched on while the relevant metal sheet (08) is being taken up by the wire frame (22) and raised; and these cyclically operated nozzles (14) are switched off before the blown air therefrom acts on the leading edge of the subsequent metal sheet (08).
