Abstract
A machine, which is designed for converting sheets into blanks for forming packages, has at least an infeed station, a processing station for cuting and creasing the sheets of material into blanks, which processing station includes an upper and lower platen and a chain transfer conveyor for moving the sheets between the platens and any additional stations, such as waste stripping stations and delivery stations. To remove a front waste held in the gripper bars of the transfer conveyor after the blanks have been separated from the sheets, the machine includes a front waste removal station positioned above the upper platen of the processing station.
