Abstract
Abstract Apparatus is provided for forming an envelope capable of containing sheet material therein having a width equal to the width of the envelope by performing the steps of: feeding a sheet having a width and a length from a tray in a predetermined direction; folding the sheet across its width into a single fold to form first and second flaps, each flap having a width equal to the width of the sheet; pressing the first and second flaps together; and applying an adhesive tape over ends of the sheet to secure the first and second flaps together to form an envelope having an internal width at least the same as the width of the sheet, the adhesive tape completely forming the ends of the envelope. An insert sheet can be folded and placed between the first and second flaps prior to pressing the flaps together and, when a portion of the second flap which extends beyond the first flap is folded over the first flap prior to applying the adhesive tape thereto, the application of the adhesive tape will completely seal the insert material within the envelope so that the sealed envelope will be outputted "ready-to-mail".
