In order to improve strength and rigidity without increasing sheet thickness, a method is provided for easily forming a rib as a reinforcing material in press-moldings and a press-molding with a reinforcing rib. This method for manufacturing press-moldings with a reinforcing rib is characterized by the following: comprises a press-molding process for simultaneously press-molding a reinforcing rib and a thermoplastic base material sheet that are each disposed in the press-molding die; the reinforcing rib being obtained by a thermoplastic rib base material and a fiber sheet material in which multiple fibers have been accumulated and bonded, both being stacked and integrally molded so as to have a main reinforcing rib portion and a bonding portion for bonding to the thermoplastic base material sheet; the fiber sheet material having voids between the fibers; and some of the heat-softened thermoplastic base material sheet entering the voids of the fiber sheet material located in the bonding portion during the press-molding process and being fixed.

The invention proposes a process and a laminating device for producing a microfluidic apparatus, wherein a film is pressed onto a backing under the action of heat and is thereby bonded to the latter. During the bonding process, the film is raised by the injection of gas on the backing side such that it cannot adhere in a non-bonding region, and is vented on the side remote from the backing. The apparatus is pressed together between a holder and a thermode of the laminating device during the lamination. A respective elastic intermediate layer is arranged between the apparatus and the holder and also between the apparatus and the thermode to make the contact pressing force more uniform and to make the bonding between the film and the backing more uniform.

The invention relates to a method for producing a fuel tank and to a fuel tank for motor vehicles. The method comprises the extrusion of web-type preforms (1), the shaping of said preforms in the first heat of the extrudate in a multi-part moulding tool in a first step to form shell-type semi-finished products (6, 6a, 6b) and in a second step in the same moulding tool (2) to form a one-piece closed container. At least one refuelling and/or operational ventilation unit (5) is fixed to the inner wall of at least one semi-finished product, in such a way that at least one pre-assembled part of the refuelling and/or operational ventilation unit comprising at least one connection fitting (5c), at least one ventilation line (5b) and at least one functional component is bonded and/or positively connected in an operation to the inner wall (7a). The wall of the semi-finished product comprising the connection fitting is punctured by the connection fitting during assembly, using at least one length-adjustable line section as part of the ventilation line.
