Abstract (en)
[origin: WO2016071080A1] The invention relates to a device for discharging exhaust air from the surroundings of a metal strip. Known devices of this type comprise at least one fan which is arranged at one side of a conveying path of the metal strip in order to generate an airflow to conduct the exhaust air in a blowing direction (BR) transverse to the conveying path. In contrast, the device (100) according to the invention has air quantity boosters (110) with an opposing suction device on the other side of the conveying path in the blowing direction in order to suction and discharge the airflow generated by the air quantity boosters together with the exhaust air. In order to reduce costs for the operation of the device, a sensor device (130) is provided in order to detect whether the metal strip (200) is present or not and at which speed the metal strip is being moved. Additionally, a controller (140) is provided in order to adjust the delivery rate of the air quantity boosters (110) and the suction device (120) depending on the measured speed.
