Claims6
An apparatus for pressing sheet-like printed products to flat bodies, comprising:
- a first pair of pressing rollers, having a first pressing roller and a second pressing roller, said sheet-like products passing between said first and said second rollers under pressure for pressing air between sheets of said sheet-like printing products;
- at least a second pair of pressing rollers having a third pressing roller and a fourth pressing roller, said at least second pair of pressing rollers being arranged downstream of said first pair of rollers, such that said sheet-like printed products are pressed twice, first by said first pair of pressing rollers and consecutively by said second pair of pressing rollers;
- and
- a drive mechanism for driving said first and second pair of pressing rollers;
- wherein one pressing roller of each pair of said first and second pairs of pressing rollers is movable away from, and toward, the respective other pressing roller via a mechanism to an extent that access for a cleaning process is achieved between each of said first and second pairs of pressing rollers;
- wherein said pressing rollers which are movable away from, and toward, the respective other pressing rollers are supported by a pivotable lever, and further wherein said drive mechanism for driving said first and second pairs of pressing rollers has drive belts which are guided around pivoting journals of said pivotable lever.
