Abstract
Abstract A venetian blind wherein the slats have channel-shaped marginal portions and the flexible strip- or cord-shaped carriers for the slats have equally spaced eyelets for the webs of metallic staples whose legs are driven through the adjacent marginal portions of the slats and are bent over behind the marginal portions to establish a permanent connection between the staples and the slats.
