Abstract
A system for detecting Poly-Bag and Poly Wrap on mail pieces, intended to be a sub-assembly on a mail unit open system that automatically opens wrapped bundles of either letter or flat mail. The system generally includes two orthogonally-opposed but otherwise identical Poly Bag Detectors both controlled by a programmable controller and deploying a swinging pendulum test, plus a Poly Wrap detector employing a rolling friction wheel test.
