Roll type closure, preferably for a sun roof

The roller blind system has first and second roller blinds (12,14) and a spool body (10) on which the two roller blinds can be accommodated one above the other. The edges of the roller blinds are displaced with respect to each other in the axial direction relative to the rotation axis of the spool body. The first roller blind is wider than the second and there is a guide for each roller blind edge.
