Abstract

The ability to stack documents properly without damaging the leading edge against the back stop 16 depends upon the pressure exerted on the document by brushes 14. Documents 18 pass in free flight under deflection spring 12 of stacker arm 9 to engage backstop 16. Document 18 rebounds out of alignment on stacker bed 17 if brush pressure is not properly adjusted. Brush pressure for varying weights and sizes of documents can be adjusted by dial 1 having face cam 2 attached to it. By rotating cam 2, spring 5 is compressed to place various amounts of pressure on arm 9 via cam follower 3 and stud 7. The latter is fixed to arm 9. Follower 3 freely moves within housing 6. Spring 11 is selected to provide the proper brush pressure with dial 1 set at zero when arm 9 is set to its shortest position.
