Abstract
A system is disclosed for picking up, depositing and transporting thin foils by use of a vacuum lifting device. The vacuum lifting device is conveyed on a traverse from a foil receiving station to a foil depositing station. At the depositing station a transport frame is provided on guide rails to permit conveyance to a processing station. At the receiving station the vacuum lifting device picks up the foil by suction at a central region of the foil such that the foil will be suspended in a curved fashion from the vacuum lifting device. At the depositing station, the vacuum lifting device is lowered so as to permit ends of the foil which are downwardly extending on both sides of the vacuum lifting device to be pushed beneath open foil clamps on the transport frame. Subsequently the clamps are closed and the foil is maintained in an extended, wrinkle free arrangement for conveyance to the processing station.
