Abstract: A rotary cutting assembly (10) is provided for cutting a panel from an envelope blank. The cutting assembly (10) comprises a cutting die (14) mounted on a die holder (16) adapted to be mounted on a drive shaft. The die holder (16) has an outer surface and a plurality of surface orifices (70) radially communicating with corresponding feed tubes (80) for supplying vacuum or air to the surface and into the vicinity of the envelope blank. The die holder (16) has a holding key (42) and a cover plate (50). An air delivery assembly (90) comprises a stationary plate disposed at one end of the die holder (16) and defining a groove member for selectively suppling vacuum or air so that when rotation of the die holder (16) aligns the feed tubes with the groove member, a supply of vacuum or air is selectively supplied at the surface orifices of the die.
