Dryer for printing machines has main unit with electrode, infrared dryer, air feed, suction units, secondary unit with electrode, air feed and suction units arranged in series above rotary cylinders

摘要

The device dries printed sheets transported over rotating cylinders and has a main dryer unit with an electrode unit, infrared dryer unit, blowing air feed unit and suction unit and a secondary unit with an electrode unit, blowing air feed unit and suction unit arranged in series above the rotating cylinders. The device dries printed sheets transported over rotating cylinders (2-4) and has at least one infrared radiation unit (19,20) for heating the sheet surface, at least one electrode unit (16,18,23,26) for connection to a high voltage source to produce an electric field directed towards the sheet surface, a blowing air feed unit (21,24,27) and a suction unit(22,25,28) . A main dryer unit (13) with an electrode unit, infrared dryer unit, blowing air feed unit and suction unit and a secondary unit (14,15) with an electrode unit, blowing air feed unit and suction unit are arranged above the cylinders in series.
