Abstract

A process for producing roller blinds includes defining a plurality of shapes for the completed roller blind in a continuous material band. The band has a uniform width and edges of the roller blind are defined between the longitudinal edges of the material band. Separating strips are defined in the material band between adjacent edges of the devices. The individual devices are removed from the continuous material band by separating the material band along the separating strips.
