Abstract

The system comprises a vacuum source and at least one vacuum cell plate providing a front surface against which an item to be held is placed and one or more cell areas in the front surface. Sealing means extends about each cell area. Conduit means are provided for connecting each cell area to the vacuum source, the conduit means including, for each cell area a valve. Each valve includes actuating means for determining when its associated cell area is completely covered by an item to be held and opening the cell area to the vacuum source only when it is completely covered by the item. Specifically, the vacuum means includes a number of cell areas with a valve associated with each cell area and arranged to open each cell area to the vacuum source only when the cell area is completely covered such that it can be evacuated.
