ABSTRACT:
A system and method for conveying and for accurately handling a generally flat object employing a plurality of support elements. The system comprises: a plurality of vacuum preload drive wheels arranged in one or more drive units, each drive unit comprising at least one vacuum preload drive wheel; one or more vacuum ports located on one or more counter plates adjacent each of the vacuum preload drive wheels, for applying induced holding down forces on the object. The vacuum ports of each drive unit are fluidically connected to a main vacuum pipe with controllable valve to a vacuum source. When the main vacuum pipe is connected to a vacuum source the normal force between the object and the vacuum preload drive wheels is increased and accordingly the lateral drive force is increased.
