Abstract
A suction device for taking-up, transporting, and depositing work pieces, ch as flat blanks of limp sheet material or panels, is equipped with a plurality of suction tubes. Each suction tube is individually connectable to a source of reduced pressure, whereby a pattern of effective suction tubes may be conformed to any particular configuration of a blank. The tubes are arranged in a housing, for example, in rows and columns. At least a portion of the housing is formed as a reduced pressure chamber. Each tube is individually connectable to the reduced pressure chamber to make the respective tube effective. Disconnection makes the tube ineffective. The connection of disconnection simultaneously moves the respective tube into a work position or into a rest position.
