Abstract

A method for folding paper into letters of the alphabet. The method has defining a rectangular piece of paper with an X-axis paralel to a width thereof and a Y-axis parallel to a length thereof, folding the piece of paper into the shape of an alphabetic letter at lines parallel to the X-axis, thereby dividing the piece of paper into a plurality of segments, in segments to be formed into curves, defining a plurality of alternative lines X' and X" parallel to the X-axis so that a sub-segment of paper between every two sequential lines X' and X" is longer than a sub-segment of paper between every two sequential lines X" and X', corrugating the piece of paper at the alternative lines X' and X", corrugating the piece of paper at lines parallel to the Y-axis, and bending the folded and corrugated piece of paper into an alphabetic shape.

1. 1. A method for folding paper into alphabet letter shapes, comprising:defining a rectangular piece of paper with an X-axis parallel to a width thereof and a Y-axis parallel to a length thereof;folding the piece of paper into an alphabetic letter at lines parallel to X-axis, thereby dividing said piece of paper into a plurality of segments;in segments to be formed into curves, defining a plurality of alternative lines X' and X" parallel to said X-axis so that a sub-segment of paper between every two sequential lines X' and X" is longer than a sub-segment of paper between every two sequential lines X" and X';corrugating the piece of paper at said alternative lines X' and X";corrugating the piece of paper at lines parallel to said Y-axis; andbending said folded and corrugated piece of paper into an alphabetic letter shape.
