<p>A cover belt for a duct, which can be swung up from a closed position by a deflecting device movable in the longitudinal direction of the duct and falls back in its closed position behind the deflecting device. The cover belt is made of a flexibly deformable material (28) with metallic reinforcements (44, 46). It has a securing strip (32), a joint strip (34) and a cover strip (36). The securing strip (32) is secured along the duct (12), the joint strip (34) connects the securing strip (32) flexibly to the cover strip (36), and the cover strip (36) spans the duct and is supported on both sides of the latter. At least one belt-shaped textile reinforcement layer (48', 48'') with essentially the same overall width as the cover belt (26) is embedded in the flexibly deformable material (28) in the area of the neutral plane of the cover belt (26). First oblong elements (44) of the metallic reinforcement are arranged between the underside (42) of the cover belt (26) and the textile reinforcements (48', 48'') so as to extend essentially at right angles to the longitudinal direction over the full width of the cover belt (26). <IMAGE></p> |
