ABSTRACT:
A device for folding sheets of paper for placement in envelopes. The device has a center planar member and two side planar members connected with hinges so that the two side members can be rotated over the center member. A laminar member with beveled edges and coextensive with the center member is attached to the center member in such a way that a sheet of paper can be inserted between them so that it extends in part beyond the center member to each side members. The user rotates each side member in turn over the center member, thereby enabling the laminar member to crease the paper. Indicator lines on one of the side members allows the alignment of the paper with respect to the laminar member so that creases are made in desired locations.
