ABSTRACT:
The sheet to be curved, such as glass at a softening temperature, is advanced on a fixed curved bed formed by a series of curved rods having different angles of inclination to form an ascending convex bed with an increasing curvature profile. The sheet is thus gradually raised and simultaneously curved by sagging of the edges. The curved rods have aligned end sections mounted in the same horizontal plane and the inclinations progressively increase. The bed is followed by a bed of constant curvature profile formed by curved rods having the same inclination. Means are provided for independently adjusting the inclination of each rod. Particular ranges of spacing and rate of advance are given.
