ABSTRACT The roll shutter, which can be louvered, exhibits at least one pull chain, the chain links (2) of which are articulated together with one another and with pivotable, lamellar louver slats (1), and at least one adjusting chain, the chain links (5) of which are articulated together with one another and with the louver slats (1). The adjusting chain links (5) overlap the pull chain links (2), and preferably the louver slats (1) also overlap the pull chain links (5) at least partially. Thereby, gaps extending through the roll shutter are avoided; the roll shutter is of a very compact structure; and the roll shutter slats exhibit a constant cross section all the way through. - 50 -
