Abstract: A substantially enhanced and improved automated mail or envelope handling system is obtained by incorporating therein the envelope content separating or staggering system of this invention. By positioning separating means in the envelope content pathway which cooperate with the envelope contents to physically separate and/or longitudinally stagger one content element relative to the second content element, the staggered portion of the rear element is easily readable by the operator in addition to the readability of the forward element. In this way, the operator is able to initiate processing of the envelope contents without being required to physically remove and separate the elements before processing the information. In the preferred embodiment, vacuum means are employed to attract and hold one of the content elements for a pre-determined duration of time, while the other element continues to advance. In this way, the desired longitudinally separation is efficiently attained.

Abstract: A unique envelope handling and sorting system is attained for efficiently and reliably separating envelopes which fail to meet pre-selected criteria from envelopes meeting these criteria by providing an envelope sensing section having at least one gauging member which comprises a plurality of separate and independent roller assemblies, each of which are securely mounted to an elongated shaft which moves arcuately in response to the thickness measuring movement of the gauging member. In the preferred embodiment, the envelope handling and sorting system of this invention also incorporates means for measuring the length of each envelope and for removing all envelopes that fail to meet the preselected length requirements. In addition, the preferred system incorporates means for effectively dividing the envelope into a plurality of separate zones and enabling the user to select any desired zone for use and evaluation of the envelope thickness measurements.
