Document set accumulator having shaft-mounted multi-grooved pulleys for tool-less adjustment of lateral belt positioning

摘要

A document accumulator capable of tool-less adjustment to accommodate a plurality of paper sizes includes first and second shafts laterally oriented across a paper path through the accumulator, first and second multi-grooved pulleys affixed to the first and second shafts, respectively, and at least one endless belt extending between the shafts, the endless belt engaging a first groove of the first multi-grooved pulley and a first groove of the second multi-grooved pulley. The belt is translatable without the use of tools into a second groove of the first multi-grooved pulley and a second groove of the second multi-grooved pulley for making a paper-size adjustment.
