Abstract: The apparatus relates, according to a first aspect, to an edge guiding arrangement, for a door having a plurality of mutually rotatable panels (2) which are extended between and movable along two elongate guides (4) at opposite edge portions (8) of the panels (2). The edge guiding arrangement comprises such a guide (4), a guide device (16) engaging and being movable along the guide (4), and a joint between the guide device (16) and an edge portion of a panel (2). The edge guiding arrangement is characterised in that the guide device (16) is rotatable relative to the guide (4) in a plane (P) perpendicular to the longitudinal direction of the guide (4), and that the joint between the guide device (16) and the panel (2) is resiliently flexible in said plane (P).
