Improved method for rolled edge forming of lampshades wherein the heat is transferred to the Lampshades (conical or cylindrical shaped) stock by conduction method, which is faster and also energy efficient. In this process the Lampshade edges get progressively pre-formed as it is heated up through progressive contact with a heated forming mould, when the full width of the shade edge gets heated up to the desired level, the edge is set on a cooling mould/tool, forming the final rolled edge. It decomes convenient and easier also for manual operation in mass production if desired.
