The object of this experiment was to investigate the possibility of obtaining pre-setting data for the 1 Farnham Rolls'. The experiment was carried out by applying certain deflections and measuring the resulting radii of curvature. Thus curves of curvature against deflection were produced for different sheet widths, and from these curves attempts to produce a conical frustum with prescribed radii were made. The results obtained can not be applied to conical parts, but this test served to indicate that it is possible to obtain pre-setting data for various applications.
