A device for dry-forming a fibrous web, in which a plurality of fibers or fiber mixtures is supplied to a forming head by means of an air flow, is described. Electrical connections to the meter socket are made to the connection strips on the switchboard cradle, whereby no rewiring of the switchboard case will be required. The unit further includes a chassis defining a chute for receiving print media therein, said chassis supporting a flat panel display, and a front bezel molding operatively fast with the rear cover molding to enclose the printer, chassis and display. The membrane is manufactured by winding around a mandrel of said at least one previously sheathed thread on the outside of the internal layer to form said at least one corded layer, deposition of the external layer on the outside of this thus wound corded layer to obtain a preform of a membrane, and molding and cross-linking under pressure of this preform in a press. Thereafter, the method also includes a procedure to decode connection payload information of a plurality of connection payloads from a Medium Access Control Protocol Data Unit. Together, the two driven wheels and the pair of additional driven wheels define a second plane.
