Systems and methods providing users with a rich web experience are disclosed. For this purpose, the heating wedge is placed onto the lower material web and is moved over the latter under pressure. A projection and at least one obstruction are positioned within the cavity. A pair of first regions defines cavity diameters sufficient to receive the bearing sets. The auxiliary eyeglass frame also includes a bridge and temporal extensions. The annular rib is able to expand radially by shape memory effect when it is subjected to a temperature greater than a transition temperature of its material to pass to a locking position of the ring on the cylindrical contact surface.
