Abstract

The documents are driven into the stacker by drive wheels 11 and 12. They enter the stack under guide 13 which cups the documents slightly. This adds to their rigidity and prevents them from cupping in the reverse direction. The documents move under pinch rolls 14 and 15, which are raised at this point, and over power rolls 16 and 17. The power rolls are rotating in the direction indicated by the arrows on pulleys 18 and 19 to force the documents down into the stack.

The documents are driven into the stacker by drive wheels 11 and 12. They enter the stack under guide 13 which cups the documents slightly. This adds to their rigidity and prevents them from cupping in the reverse direction. The documents move under pinch rolls 14 and 15, which are raised at this point, and over power rolls 16 and 17. The power rolls are rotating in the direction indicated by the arrows on pulleys 18 and 19 to force the documents down into the stack.

As a document passes sensing post 20 the diaphragm mechanism 21 is actuated, pulling the pinch rolls 14 and 15 down into contact with the surface of the document. Such action decelerates its forward motion. Power rolls 16 and 17 now operate on a large surface area of the document to force it down into the stack.
