Abstract

An effective document cornering station is provided which is particularly suited to handle hand fed documents. Documents 10 are fed one at a time from the stack resting on support surface 15. It is only necessary to imprecisely push the document through opening 25 into the bite formed between urge roll 30 and pressure ball 35, Fig. 1. This is illustrated by the document in position B. Urge roll 30, in cooperation with ball 35, moves the document from the entry position to a position where it comes between aligner roll 40 and cooperating idler roll 45, Figs. 1 and 2. This is represented by the document in position C. Aligner roll 40 is of the type shown and described in U.S. patent 3,148,877. Aligner roll 40 causes the document to pivot about point 50 until it is fully cornered, as represented by position D.

Document Cornering Mechanism

An effective document cornering station is provided which is particularly suited to handle hand fed documents. Documents 10 are fed one at a time from the stack resting on support surface 15. It is only necessary to imprecisely push the document through opening 25 into the bite formed between urge roll 30 and pressure ball 35, Fig. 1. This is illustrated by the document in position B. Urge roll 30, in cooperation with ball 35, moves the document from the entry position to a position where it comes between aligner roll 40 and cooperating idler roll 45, Figs. 1 and 2. This is represented by the document in position C. Aligner roll 40 is of the type shown and described in U.S. patent 3,148,877. Aligner roll 40 causes the document to pivot about point 50 until it is fully cornered, as represented by position D. A series of subsequent aligner rolls assure that the document is fully aligned before entering a work station such as a document read station, not shown.

Urge roll 30 is continuously running. Aligner rolls 40 can be continuously running or clutched. Clutching the aligner rolls permits an operator to perform an operation while another document is at the work station.
