[0002] At present, in the known paper boats that can float on the water, the thickness of each part of the hull is uneven, and the bottom of the boat that floats on the water and touches the water is the thinnest, with only a single layer of paper; the side of the boat is thicker, but it does not help the overall resistance of the paper boat

Embodiment Construction
[0032] A dotted line is used to indicate the positive fold line of the front half fold, that is, when folding, the front and the front of the paper are folded relative to each other; a solid line plus a circle indicates the reverse fold line of the reverse face fold, that is, when the paper is folded, the back and the back of the paper are folded opposite each other; the solid line plus a dot indicates the indicator line ;
[0033] Take a rectangular paper that is vertically long and horizontally wide, and make three vertical folding lines, from left to right are the left vertical forward folding line, the middle vertical reverse folding line, and the right vertical forward folding line. The three vertical folding lines divide the rectangular paper into four vertical rectangles equally. From left to right, it is the first vertical rectangle, the second vertical rectangle, the third vertical rectangle, and the fourth vertical rectangle; from the endpoint of the left longitudinal...

A practice of paper boats relates to a method of making paper products. Take a rectangular piece of paper that is vertically long and horizontally wide, and make vertical folding lines and oblique lines at the corners of the paper; fold the four corners of the paper; make overlapping vertical rectangles, and make positive folding lines with upper oblique lines and lower oblique lines, and then fold Form a multi-layer isosceles trapezoid; stretch the lower interlayer of the multi-layer isosceles trapezoid from the inside to the outside, fold and flatten the upper and lower bottom corner vertices toward the middle; make a connecting line and reverse the folding line to form two isosceles triangles; Fold the isosceles triangle on the opposite side of the hexagon according to the reversing line of the connecting line, the upper and lower quadrilaterals on the front become two pentagons, and the whole hexagon becomes an octagon; unfold the two pentagons, Form a concave shape as a whole; turn the concave shape 180 degrees to form a convex shape; press the convex shape to form a concave shape, that is, a paper boat. The design is ingenious and the structure is reasonable; the folding is easy and the operation is simple; all parts of the hull are flat and beautiful in shape.
Description
technical field [0001] The invention relates to a method for making a paper product, in particular to a method for making a paper boat. Background technique [0002] At present, the known paper boats that can float on the water have uneven thickness of the various parts of the hull, and the bottom of the boat that floats on the water and touches the water is the thinnest, with only a single layer of paper; Contents of the invention [0003] In order to overcome the existing paper boats that can float on the water, the thickness of each part of the hull is uneven. The bottom of the boat that floats on the water and touches the water is the thinnest, with only a single layer of paper; the side of the boat is thick, but it does not help the paper boat as a whole to withstand immersion. To solve the deficiency, the invention provides a method of making a paper boat. [0004] The technical scheme adopted by the present invention to solve its technical problems is: take a recta...
