Method of folding sheet materials via angled torsional strips

摘要

One embodiment described herein is a sheet of material 200 formed into accurate and high value structures by implementing a plurality of elongated slots 202 that are obliquely placed along a fold line 204 which create one or more strips 206 consisting of a length w, a width s and an angle f to said fold line 204. The strips 206 are put into a state of plastic deformation through torsion which is controlled via the combination of said length w, width s, and angle f elements to create accurate, unique, complex and high value products or forms. The embodiments described allow for a greater degree of freedom of sheet material types, a greater degree of sheet material thicknesses, while simplifying implementation. This and other embodiments are also enclosed.

1. A method for folding two adjacent sections of sheet material about an interposed fold line to form a three dimensional folded form, said method comprising:
(a) forming a plurality of elongated slots through said sheet material, wherein said slot is substantially centered on and oblique to said fold line, said slots form a plurality of substantially parallel elongated strips along the length of said fold line, said strips connect said adjacent sections of said sheet material (b) folding said adjacent sections of sheet material about said fold line, wherein said strips encourage said sheet of material to fold at said fold line by twisting along said strip's length w, whereby said sheet material can be folded into accurate, precise and complex structures.
