Abstract
A gripping head (1) comprises a plurality of vertical, spaced laminae (3) defining a gripping aperture (4) for gripping a sheet (7) to be stretched. The laminae (3) are welded at one edge to flanges of a horizontal cross member. In order to facilitate the welding, and to reduce the stress concentration factor at the weld, fillers (11) are arranged between the laminae at the said edge and the weld is a butt weld (13). After welding, the ends of the fillers (11) at the weld seam (13) are bored out (18) to remove cracks, or gaps (16, 17) between the fillers (11) and the laminae (3).
