Abstract
The invention pertains to a process and device for the gripping at a storage station, transfer and placement of a sheet of flexible plastic material at the stacking station in an automatic production process for compound structures, especially compound panes. In accordance with the process, the sheet made of flexible plastic material is grasped by suction connected to a swinging stamp, first exerting suction on the median part of the sheet, while extending this suction progressively up to one end of the sheet, then by swinging back, extending said suction over the entire surface thereof, while the sheet is simultaneously placed flush on its support, generally the subjacent sheet.
