Abstract (en)
[origin: EP0364737A2] Blowing devices for loosening sheets in the feeders of rotary printing machines are described which are arranged on the frame (3) of the feeder laterally next to the sheet stack (2) so as to be adjustable in height and width and so as to be controllable in the blowing output. These blowing devices for loosening sheets consist of ventilators (1), the airflow of which, directed towards a lateral surface of the sheet stack (2), can be adjusted at an angle relative to said lateral surface. <IMAGE>
