Abstract

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.

ROLLER DRUM PEEL-ON BOTTOM STACKER (Cont'd)

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.

In the simplest configuration, Figure 1, the drum is split into two halves 8,9 and a respective endless belt 1,2 is wrapped around each half. Rollers 6 are provided to enable each belt 1,2 to be moved around its respective drum half 8,9 when required. Initially, the split 10 between the drum halves 8,9 lies horizontally and the document stack 4 is supported on belt 1. A document is fed in between the drum halves 8,9 by moving belt 2 around its drum half 9 and, with belt 2 stationary, the document 3 is held pneumatically. Next, the complete drum assembly is rotated wit...
