Abstract
Method for folding plane surfaces wherein, given a plane surface on which there are identified a pluratity of alternative primary folding lines and, parallel to each other and capable to generate a wavy structure, each primary folding line is linked to the subsequent primary folding line by means of two further secondary folding lines, having same origin on the folding line and diverging between them them with angles .beta. and .GAMMA. with respect to the perpendicular to the lines, being 0.ltoreq..beta.<90.degree. and .beta.<.GAMMA.<90.degree., said joining being performed at least once, then two additional secondary folding lines, corresponding to the previous and, being traced, specular with respect to a simmetry plane passing through the said primary folding line.

A method for folding a planar surface comprising the steps of:
- (a) forming a series of parallel folding lines on said surface, the number of said parallel folding lines being an odd integer greater than 3;
- (b) linking a first parallel folding line with a next adjacent parallel folding line through primary and secondary folding lines having a common origin on said first parallel folding line and diverging from each other, so that said primary folding line forms an angle .beta., with 0<.beta.<90.degree. with respect to a line perpendicular to said parallel folding lines and said secondary folding line forms an angle .GAMMA., with .beta.<.GAMMA.<90.degree. with respect to said same perpendicular, said primary and secondary folding lines being specularly arranged with respect to the next adjacent parallel folding lines and respectively defining opposite directions of folding with respect to each other;
- and
- (c) folding said planar surface along said parallel folding lines such that each parallel folding line is directionally opposite the next adjacent parallel folding line so as to assume an accordion shape, while folding said primary and secondary folding lines in their respectively opposite directions to collapse adjacent planar surface portions on themselves in directions perpendicular to said folding lines without distortion due to the specular arrangement of the primary and secondary folding lines.
A method for folding a sheet material having a flat planar and continuous surface comprising the steps of;
- (a) forming a series of equally spaced parallel folding lines on said surface, the number of said parallel folding lines being an odd integer greater than 3;
- (b) linking a first parallel folding line with a next adjacent parallel folding line through primary and secondary folding lines having a common origin on said first parallel folding line and diverging from each other, so that the primary folding line forms an angle .beta., with 0<.beta.<90.degree. with respect to a line perpendicular to said parallel folding lines and said secondary folding line forms an angle .GAMMA., with .beta.<.GAMMA.<90.degree. with respect to said same perpendicular, said primary and secondary folding lines being specularly arranged with respect to the next subsequent parallel line and respectively defining opposite directions of folding with respect to each other;
- and
- (c) folding said material along said parallel folding lines in successively opposite directions such that the material assumes a generally accordion shape, while folding said primary and secondary folding lines in their respectively opposite directions to collapse adjacent material portions on themselves in directions generally perpendicular to said folding lines without distortion, due to the specular arrangement of said primary and secondary folding lines.
A method for folding a sheet material having a flat planar and continuous surface comprising the steps of:
- (a) forming a series of equally spaced parallel folding lines on said surface, the number of said parallel folding lines being an odd integer greater than 3, each said parallel folding lines defining a fold opposite the next adjacent folds;
- (b) linking a first parallel folding line with a next adjacent parallel folding line with primary and secondary folding lines having a common origin on said first parallel folding line and diverging from each other, so that said primary folding line forms an angle .beta., with 0<.beta.<90.degree. with respect to a line perpendicular to said parallel folding lines and said secondary folding line forms an angle .GAMMA., with .beta.<.GAMMA.<90.degree. with respect to said same perpendicular, said primary and secondary folding lines being specularly arranged with respect to the next adjacent parallel folding lines and respectively defining opposite directions of folding with respect to each other;
- (c) forming additional primary and secondary folding lines repeated in symmetry;
- (d) forming additional primary and secondary folding lines repeated in progression;
- and
- (e) folding said material along said parallel folding lines such that each parallel fold is directionally opposite the next adjacent parallel fold so as to assume an accordion shape, while folding said primary and secondary folding lines in their successively opposite directions to collapse adjacent material portions on themselves in directions generally perpendicular to the folding lines without distortion due to the specular arrangement of the primary and secondary folding lines.
