Claims (1)

Patentanspruch :Claim: Rolladen aus ebenen Metallplatten, die durch schneckenförmige Ausbiegungen an den Längskanten miteinander verbunden sind und deren Höhe, in aufgewickeltem Zustande des Rolladens betrachtet, von innen nach außen je Lage größer wird,, dadurch gekennzeichnet, daß die eine Längskantenabbiegung (1) jeder Platte sich unmittelbar schneckenförmig an die Plattenebene anschließt, der schneckenförmige Teil der anderen Längskantenabbiegung (2) jedoch durch eine zur Plattenebene schräg verlaufende Fläche (3) ohne kantigen Übergang mit der Plattenebene dergestalt verbunden ist, daß zwischen gekuppelten Abbiegungen 'eine Rinne entsteht, die bei Aufwicklung zur Aufnahme des entsprechenden Abbiegungsvorsprunges der nächsten Wickellage 'dient.Roller shutters made of flat metal plates, which are attached by helical bends the longitudinal edges are connected to one another and their height, viewed in the rolled-up state of the roller shutter, from inside outwards for each layer is larger, characterized in that the one longitudinal edge bend (1) Each plate is directly connected to the plane of the plate in a spiral shape, the spiral-shaped one Part of the other longitudinal edge bend (2), however, by a surface (3) which is inclined to the plane of the plate and is not angular Transition with the plate plane is connected in such a way that between coupled Bends' a groove is created which, when wound up, is used to accommodate the corresponding Bending projection of the next winding layer 'is used.
