The disclosed invention is a drum which accepts documents 3 and then restacks them to the bottom of a document stack 4. A document stack 4 is supported on a band 1 of flexible material which itself has a rigid support 5 beneath. The rigid support 5 is slid from beneath the document 4 stack and the flexible band 1 peeled away. As this operation proceeds, a similar arrangement of band 1 and support 5 moves in to support the document stack 4. A new document 3 is fed up through the gap 10 between the two band and support assemblies, and is progressively stacked on the bottom of the document stack 4 as the assemblies continue to translate beneath the bottom of the document stack 4. The rigid supports 5 may be in the form of two drum halves 8,9, i.e. a double 'D' design. Variants include three and five segment arrangements.
