ABSTRACT:
An improved conveyor system for transporting die-cut blanks from a rotary die cutter to a blank stacking device includes a blank take-up section comprising a spring biased take-up guide which insures that blanks are positively engaged by the conveyor system before they are released by the die cutter. The conveyor system includes a vacuum belt which serves to suspend and transport die-cut blanks while maintaining them in precise registry to a blank stacking device. An improved snubbing device is disclosed which decelerates blanks without damage to the blanks themselves and then causes the decelerated blanks to rebound back toward the die cutter for improved stacking. A ramp structure is disclosed which flexes blanks near the blank release section of the conveyor system such that the trailing edge of transported blanks snap away from the conveyor system, thereby positively disengaging the blanks from the conveyor.
