Fascinating and elegant shapes may be folded from a single planar sheet of material without stretching, tearing or cutting, if one incorporates curved folds into the design. We present an optimization-based computational framework for design and digital reconstruction of surfaces which can be produced...
2c, d). The representative elementary building unit of SFGMs is similar to the simple but intriguing self-assembled graphene observed in recent experiments and simulations: the spontaneous self-tearing and peeling off towards the formation of a micrometer-size folded graphene.49,50,51 Molecular ...
Method and device for folding a paper web In the folding of a paper web (3), to which a fold-assisting liquid is applied along the fold line before the folding operation, a precise, sharp fold can be achieved and, at the same time, the risk of tearing and damage can be avoided b....
tearing along the line by a user. A type of “score” which functions much like a “perforation” is the “tearing score”, in which the fibers of the carton board are cut approximately halfway through the carton board to permit tearing along the score lines. A tearing score can, of ...
it easier to collapse the structure and can also enable a more flat compact structure in the closed or collapsed configuration. Other benefits are that such configurations can prevent tearing and prevent bad alignment of the assembly. For example, at any place where additional stress is introduced...
