  • Patent number: 5238123
    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.

  • Patent number: 5147169
    Abstract: By providing a pair of vacuum manifolds positioned on opposite sides of an envelope travel path with the vacuum manifolds being laterally spaced apart, a unique, effective and dependable envelope handling system is achieved whereby the envelope sides are consistently separated and the contents removed therefrom and positioned in a readily accessible channel. Preferably, the envelope handling system also incorporates sensing devices for automatically and separately inspecting each side of the envelope to determine the presence of additional material which should be processed. In this way, any such material is automatically discovered for handling by the operator.
