Description

Technical Field

[0001] This application relates to the technical field of printing press equipment, and particularly to a debris separation device for a printing press. Background Art

[0002] Both sides of the existing bills are provided with a whole row of holes. Before printing, holes need to be punched in the bills, and then they are conveyed to the printing device.
