Abstract
In apparatus for conveying successive stacks of sheets to a station at which an operation is to be performed on the stack, the sheets are advanced by pushing elements (14) to the station, at which a resilient finger (17) projects through a slot (16) in the track. The finger (17) aligns the leading edges of the sheets in the stack. When the stack of sheets is to be advanced, a slide (20) retracts. The finger (17) is pivotally mounted on the slide and its upper inclined edge engages the bottom rear corner of the slot when the slide is retracted, causing the finger to sink below the track until the slide is returned in time for the alignment of the next stack.
