Apparatus and method for forming collations of two different size documents

Apparatus for accumulating two different size documents to form a collation, comprising:

• a first ramp guide block defining an upstream end of a first stacking area for smaller ones of the documents;
• a second ramp guide block defining an upstream end of a second stacking area for larger ones of the documents;
• means for transporting both the smaller and larger of the documents over said first and second ramp guide blocks;
• and
• means for registering the lead edge of both the smaller and larger ones of the documents after said documents have been transported over said first and second ramp guide means.

Apparatus for accumulating two different size documents to form a collation, comprising:

• a first accumulator pocket having first means for individually transporting, stacking and registering at least one smaller one and one larger one of said documents to form a first collation of said smaller and larger documents;
• a second accumulator pocket superposed over said first accumulator pocket, said second accumulator pocket having second means for individually transporting, stacking and registering at least one smaller one and one larger one of said documents to form a second collation of said smaller and larger documents;
• and
• diverting means situated upstream of said first and second pockets for diverting said smaller and larger documents to one of said first and second accumulator pockets, wherein each of said first and second accumulator pockets includes a first ramp guide block defining an upstream end of a first stacking area for smaller ones of the documents and a second ramp guide block defining an upstream end of a second stacking area for larger ones of the documents.
