Abstract: The invention relates to a printing machine with hybrid printing technology for printing on a continuous material web.

Abstract: The invention relates to a suction jet pump (12), composed of a housing (18) having a connection (24), a propellant line (14), a propulsion jet nozzle (19), a mixing tube (15) which adjoins said propulsion jet nozzle (19), and a suction point (13) arranged upstream of the mixing tube (15). In addition, the suction jet pump (12) has a second suction point (16).

Abstract: A process and an apparatus for continuously sheathing solid or hollow profiles (1), especially tubes, with an extruded foam jacket (3) of thermoplastic synthetic resin is provided. To this end a foam jacket is extruded, slit open, and into the slit foam jacket (3) the solid or hollow profile (1) to be sheathed is continuously coaxially introduced at synchronous speed. The slit foam jacket is closed by welding after the introduction. The process steps of slitting the foam jacket, introducing the profile to be sheathed into the foam jacket, and closing the foam jacket (3) by welding are to be carried out at temperatures of the foam jacket above the glass transition temperature of the synthetic resin material of the foam jacket. After the slit in the foam jacket (3) has been closed by welding, the jacket cools down and snugly shrinks onto the profile to be sheathed.

Abstract: The present invention relates to a method for the manufacture of moulded bodies such as cornices from foam plastics material, the visible side of these bodies being heavily textured or profiled, smooth, non-porous and free from separation elements, with a unit weight of less than 200 kg/m.sup.3. In the method, a thin, elastic, heat-deformable film (3) is inserted between two heated mould portions (1, 2) in such a way that the film edges are clamped between the superimposed mould edges of the two mould portions (1, 2), a reactive, heat emitting, foaming plastics mixture is introduced through the upper mould portion (1) in such a way that it may be distributed on the film, and the hollow chamber formed between the film and the lower mould portion is evacuated during foaming, such that the film intimately conforms to the shape of the lower mould portion.
