Abstract
Abstract A cover or the like consisting at least of one woven plastic web, provided at least on one side with a plastics foil, and for covers of comparatively large width composed of a number of such webs in either butted or slightly overlapping relationship. For reinforcement purposes, there is applied at least at two opposite sides an edge strip of similar, at least equally strong material as the cover. Spaced apart from the respective lateral edges, there are formed attachment holes, whereby a reinforcement cord in the longitudinal central region of the respective strip, substantially parallel to the respective lateral edge of the cover, is embedded between the edge strip and cover, while the said attachment holes are formed in the region inwardly adjoining the said reinforcement cord, through the edge strip and cover.
