Abstract

The invention is directed to an apparatus and method for making an envelope from ordinary size, readily available, writing paper. Preferably, the apparatus is a compact desk-top size machine that can be combined with any common office printer, such as a laser printer, or even be incorporated thereinto to form a single machine. The apparatus enables the provision of a system for integrating and simplifying office computerized printing of letters and addressing of envelopes, by using a single paper tray whereby, for example, following the printing of a letter on one or more sheets of paper, the subsequently fed final sheet of paper from the paper tray is routed to the envelope making apparatus, perhaps after the printing of an address on the final sheet, whereby an envelope is created.
