Abstract: A first sheet of large (e.g. 81/2.times.11 inch) size and a second sheet connected by adhesive to the first sheet only at a reply envelope portion, form a mailer type business form. The first sheet is eccentrically Z-folded about fold lines to produce the mailer, with permanent adhesive sealing the panels of the mailer together, the return envelope being disposed within the mailer. Located next to the return envelope inside the mailer, separated by a perforation line, is a reply statement portion having reply statement indicia printed on it. The entire intermediate may be simplex printed because of its eccentric Z-shape configuration.

Abstract: A mailer type business form having four parts is produced from two sheets, to define a mailer having top and bottom plies formed from one sheet, and first and second intermediate plies formed from another sheet. The top and first intermediate plies have aligned die cut windows in them, and the second intermediate ply forms a return envelope with the bottom ply. A combination outgoing address for the mailer, and return address for the return envelope, are printed on a portion of the second intermediate ply readily visible through the die cut windows. During production of the mailer, slugs are cut out of one of the sheets, and removed by vacuum or a blast of pressurized gas, and the first and second sheets are merged together, adhesive being applied to the sheets to attach them together.
