Abstract

A sheet stacker in which the motion of sheets entering the stacker is damped by one or more rollers (5) arranged to lie on top of the stack being compiled on a support surface (1), which roller (5) is rotatable only in the direction corresponding to that which sheets enter the stacker. In this way sheets are prevented from bouncing back from an end registration stop (2) against which they are registered so as to improve registration of the stack.
