Abstract: A sealing machine and method are described as used for sealing the edges of documents so that envelopes are not needed. In known such machines, particularly when used for sealing the documents by pressure, problems arise if documents overlap either partially or fully (i.e. a double document) because the pressure rollers in the machine easily jam. The documents being sealed may be very valuable (e.g. pay slips) and any loss or damage is a serious problem. The invention therefore provides means for sensing the presence of double or overlapping documents in a feed path of the machine and means for diverting such double or overlapping documents upstream of the sealing means. Both the thickness and the length of the documents are measured and compared to preset values, such as may be stored in a microprocessor either from ideal figures or from measurements taken during a controlled start-up procedure.
