ABSTRACT A machine for shaping flat metal strip into a channel-section form comprises a succession of aligned pairs of rollers through which the strip can be fed to shape it into the channel-section form. The rollers are arranged also to form a curl or flange progressively along a lengthwise extending edge of the strip. Alternatively the curl or flange may be formed in an initial step, and in this case the rollers include means for accommodating the curl or flange for positively laterally locating the strip in its passage through the succession of rollers.
