Abstract

This separator mechanism comprises a pair of upper restraint rolls 1 having peripheries which are spaced from the periphery of lower separator roll 2. This space, a fixed throat of predetermined width, is wider than the maximum thickness of one document and narrower than the minimum thickness of two documents. Rolls 1 and 2, (A), are driven counterclockwise by shafts 3 and 4, respectively. Loosely mounted on shaft 3, between upper rolls 1, is weighted roll 5. This has an oversize bore 6 so that it is gravity biased toward contact with roll 2, (also B).

This separator mechanism comprises a pair of upper restraint rolls 1 having peripheries which are spaced from the periphery of lower separator roll 2. This space, a fixed throat of predetermined width, is wider than the maximum thickness of one document and narrower than the minimum thickness of two documents. Rolls 1 and 2, (A), are driven counterclockwise by shafts 3 and 4, respectively. Loosely mounted on shaft 3, between upper rolls 1, is weighted roll
5. This has an oversize bore 6 so that it is gravity biased toward contact with roll 2, (also B).

When a document is fed leftward into the throat between rolls 1 and 2, roll 5 biases the document down into contact with roll 2 to assure positive feeding. Roll 5 is driven clockwise by the document and thus does not scuff it. This arrangement is especially suitable for use within a document length from hoppers of the type in which documents are fed from the bottom of the stack.

In an alternative arrangement, weighted rolls are loosely mounted at opposite sides of a single, upper restraint roll.
