Abstract
For use on a cyclically operating envelope inserter having a rotating member and a reciprocating member linked to the rotating member, a system for establishing an absolute reference point for timing a cycle of the apparatus that comprises an encoder for ascertaining rotational angle values for the rotating member linked to a detector for establishing for the reciprocating member a first reference point and a second reference point as the reciprocating member moves, wherein the first and second reference points are in terms of the ascertained rotational angle values. Additionally, a controller is provided that is responsive to the detector and encoder for determining from the first and the second reference points a rotational position for the absolute reference point.
