Abstract
A device for enhancing the transport of sheets in a printing machine is constructed upstream of the image transfer station to flatten the paper against the transport belt or drum on which it is riding. An air cushion is generated by expelling pressurized air through an array of holes to provide an air bearing for the sheets as it travels in its transport path. The air cushion is designed to flatten the paper against the belt or drum.
