ABSTRACT:
A front stop for a feeding device has a planar lower surface connected to a round part and is provided with a bore, which is connected to a fluid source and has channels extending to the planar flat surface to enable a flow of fluid between a blank being fed under the stop and the next following blank of a pile of blanks in the feeder. This flow of air creates a cushion which reduces damage to the surfaces of the blanks, such as printed surfaces.
