ABSTRACT:
An apparatus is provided for folding either of two size sheets of paper, such as letter and legal size paper, for insertion into an envelope. The apparatus includes a planar base and a pair of opposed structures against which a sheet of paper to be folded may be placed for positioning of the sheet. A folding bar is mountable at one several preselected positions on the base such that the sheet to be folded passes between the folding bar and the base. Preferably, a creasing bar is provided for applying pressure to a surface of the sheet to be folded causing the sheet to be pressed tightly against the folding bar such that a crease is formed across the sheet at a preselected location corresponding to the first fold of the sheet, The base and the folding bar are provided with a detent mechanism such that the folding bar may be readily, moved to the appropriate position for creation of the initial crease and the particular size of paper to be folded. A method of folding the sheets of paper is also disclosed. The pressure applied to form the initial crease may be formed in various manners, including the application of finger pressure.
