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.
Claims18
A device for folding sheets of paper, said device comprising:
- a first member;
- a second member;
- hinge means for attaching said first member to said second member so that said first member can rotate about an axis with respect to said second member;
- a laminar member having an edge, said laminar member attached to said first member so that said edge is just off said axis, said laminar member carried by said first member so that said sheet of paper can be placed between said laminar member and said first member with a portion of said paper extending beyond said first member to said second member, said laminar member creasing said sheet of paper when said second member is rotated about said axis with respect to said first member.
A device for folding a sheet of paper, said device comprising:
- a first side member having a first edge;
- a center member having a first edge and an opposing second edge;
- first hinge means for attaching said first edge of said first side member to said first edge of said center member, said first hinge means enabling rotation of said first side member with respect to said center member about a first axis;
- a second side member having a first edge;
- second hinge means for attaching said first edge of said second side member to said second edge of said center member, said second hinge means enabling rotation of said second side member with respect to said center member about a second axis;
- and
- a laminar member dimensioned to cover said center member and having a first edge adjacent to said first edge of said center member and a second edge adjacent to said second edge of said center member, said laminar member attached to said center member so that said sheet of paper can be placed between said center member and said laminar member, a first portion of said paper extending beyond said center member to said first side member and a second portion of said sheet of paper extending beyond said center member to said second side member, said laminar member making two spaced-apart creases in said sheet of paper when said first and second side members are rotated about said first and second axes respectively.
A device for folding a sheet of paper, said device comprising:
- a first side member having a first edge;
- a center member having a first edge and an opposing second edge;
- at least one first hinge joining said first edge of said first side member to said first edge of said center member so that said first side member can rotate about a first axis with respect to said center member;
- a second side member having a first edge;
- at least one second hinge joining said first edge of said second side member of said second edge of said center member so that said second side member can rotate about a second axis with respect to said center member;
- and
- a laminar member attached to said center member and having a first beveled edge and a second beveled edge and being coextensive with said center member so that said first beveled edge is just off said first axis and said second beveled edge is just off said second axis, said laminar member carried by said center member so that said sheet of paper can be placed between said laminar member and said center member, a first portion of said paper extending beyond said center member to said first side member and a second portion of said sheet of paper extending beyond said center member to said second side member, said laminar member making two spaced-apart creases in said sheet of paper when said first and second side members are rotated about said first and second axes respectively.
