Pneumatic scrap reduction system for rotary die cutter

Image Number 6 for United States Patent #4781088.

A rotary die cutter system minimizes the amount of scrap between successive blanks cut from web material by holding the web against backward movement at a position spaced upstream from the nip defined by the die and anvil cylinders, retracting the cut leading end of the web through a predetermined distance by means of a fluid pressure cylinder in response to release of the web by the cut-off knife at the trailing edge of the die on the die cylinder such that on the next cycle, the leading edge of the die will engage the web at a position spaced so close to the retracted leading end of the web that contiguous portions of a single blank can be cut from the web during successive revolutions of the die cylinder.
