ABSTRACT:
A sheet stacking apparatus in which resilient strips of plastic material are fixed at one end just below an exit slot of a feed arrangement for sheets or sets of sheets. The strips extend over a catch tray positioned below the exit slot. In use, the strips are deflected by an amount substantially proportional to the weight of sheets in the stack which they partially support, so that the top sheet in the stack is always at substantially the same height above the catch tray base. The leading edges of fed-out sheets or sets always encounter a support surface at a constant position whereby curling or rolling up of fed-out sheets or sets is prevented.
