Abstract
The present invention relates to an improved drum assembly for washing and drying machines, in which the section of the wedge elements (8) facing the drum ring (3) and provided for engaging with the latter is formed, before the drum assembling, with an edge (9) defined by an inwardly turned wall of the wedge element and parallel to the surface of the front ring (3). This front ring is in turn provided, at each wedge element (8) with a window (10) the contour of which is so deformed as to provide a deformed portion (11) adapted for firmly engaging the edge (9). The invention provides a direct mechanical coupling between the wedge elements and front ring element, i.e. a mechanical coupling which does not comprise any welding spots susceptible to favor oxidation and sealing failure problems of the made connection.
