Abstract

Nowy sposób składa się z pierwszego etapu, w którym wzdłuż krawędzi wzdłużnej (6) pierwszego arkusza (3) wykonuje się zagięcie i jednocześnie wzdłuż krawędzi wzdłużnej (8) drugiego arkusza (4) wykonuje się zagięcie w kształcie złożenia w „S”. W drugim etapie, środkowa część złożenia w „S” jest rozwijana. Pierwszy etap przeprowadzany jest za pomocą urządzenia składającego się z pięciu elementów, które w jednym kroku wykonują zagięcie i złożenie w „S”.
