Abstract
A roller shutter slat has hollow sectional slats (1) with a central part (1c), two edge parts (1a) and transverse grooves (1b) arranged therebetween for receiving bearing or adjusting links (3, 4). The edge parts (1a) and the central parts (1c) are spaced apart and interconnected by linking elements (5, 6, 40, 41) inserted into hollow chambers (26) of the hollow sectional slat (1). The cross-section of the linking elements (5, 6, 40, 41) is narrower than the cross-section of the hollow chambers (26) and the linking elements (5, 6, 40, 41) are linked to the hollow sectional slats (1) by tongue-and-groove joints (9, 10; 42, 43). Easy-to-produce grooves (1b) are thus created without weakening the roller shutter slat (1) in the area of the grooves (1b).
