Abstract:
Stacking apparatus for sheets which may be curled comprisinga support surface upon which individual ones of said sheets may be moved,a first reference surface against which said sheets can be moved across said support surface to be located in a first direction by said first reference surface,a second reference surface against which said sheets can be moved across said support surface to be located in a direction perpendicular to said first direction,an eccentric member having a high section and a low section located over said support surface, said eccentric member being rotatable to locate said high section over sheets being moved across said support surface toward said first reference surface,a clamp member lightly biased toward said support surface having an angled surface to guide a sheet moved across said support surface while said high section holds the sheet downward against curl, movement of said sheet forcing said clamp member open by overcoming said bias, wherein said sheet is clamped by said clamp member, andwherein said eccentric member rotates to present said low section over said support surface when a subsequent sheet drops onto said support surface so several sheets can be stacked on said support surface in a regular stack defined by said first reference surface and said second reference surface.
