Abstract (en)
A one-piece mailer is produced from a one-piece blank produced as such or which is part of an assembly of interconnected one-piece blanks, the one-piece blank having at least two contiguous sections disposed for folding over on each other into overlying relation, each section having remoistenable glue along the respective longitudinal edges for bonding the sections together. Optionally glue is also disposed near a transverse edge of one of the sections. An apparatus is described for folding and sealing such blank comprising feed means, means for applying water to at least one side of the blank being conveyed along each longitudinal edge and means for folding the sections of a conveyed blank into overlying relation while pressing the opposed longitudinal edges together to permit the activated glue to bond the edges together.
