ABSTRACT:
An elongated arch forming member or bar supported upon a horizontal stacking station base by a movable support for permitting the stack to be lowered as the weight of the of sheets over the arch forming member increases. The arch forming member supports the sheets only at centralized portions thereof for permitting edge portions of the sheets to be pulled downwardly by gravity to form an arch, in the stack of sheets, transverse to the direction of feed of the sheets from a printer or source machine into a receptor station. The arch forming member is oriented parallel to opposite edges of the sheets and causes an angle of at least 15.degree. to be produced between the edge portions of the sheets and the horizontal plane of the base.
