Abstract:
A multi-row punch die for punching pages permits a single die to accommodate a plurality of lines of pins. The multi-row punch die reduces the need for multiple punch dies. This allows for quick engagement and disengagement of rows of punch pins being used to punch the pages. The multi-row punch die preferably floats pins not being used out of the way from contact with pages being punched, or allows for their removal.
