Abstract
A drying station for drying printed sheets transported by a transport belt includes an irradiation device for irradiating the printed sheets, a deflection section located in vicinity of the irradiation device for guiding the transport belt away from the irradiation device, and a shielding device disposed between the transport belt and the irradiation device for shielding the transport belt against radiation from the irradiation device while the sheets are exposed to the radiation. A printing machine including the drying station and a method for drying printed sheets are also provided.

A drying station for drying printed sheets transported by a transport belt, the drying station comprising an irradiation device for irradiating the printed sheets, a deflection section located in vicinity of said irradiation device for guiding the transport belt away from said irradiation device, and a shielding device disposed between the transport belt and said irradiation device for shielding the transport belt against radiation from said irradiation device while the sheets are exposed to the radiation.
A printing machine having a drying station for drying printed sheets transported by a transport belt, the printing machine comprising an irradiation device for irradiating the printed sheets, a deflection section located in vicinity of said irradiation device for guiding the transport belt away from said irradiation device, and a shielding device disposed between the transport belt and said irradiation device for shielding the transport belt against radiation from said irradiation device while the sheets are exposed to the radiation.
A method for drying printed sheets, which comprises:
- conveying the sheets by a transport belt into the vicinity of an irradiation device;
- separating the sheets from the transport belt, at least in some regions, before guiding the sheets past the irradiation device;
- guiding the transport belt and guiding the sheets separated from the transport belt, past the irradiation device;
- and
- subjecting only the sheets to irradiation for accelerating drying thereof, while shielding the transport belt from the irradiation.
