Abstract: Process and apparatus for joining endless polymer materials by means of the transillumination technique. According to the invention, in order to be joined, the endless materials are guided through two contrarotating rollers that press against each other. The first roller consists of a material that is transparent to laser beams and is tubular. The second roller is formed from a material that can be deformed easily at the surface, so that its surface can adapt to the shape of the first roller. Devices for producing a laser beam at the contact surface between the materials to be joined are arranged in the first roller. In this case, the beam is formed as a linear laser beam longitudinally with respect to the direction of movement of the materials so that during the passage, continuous heating of the material up to the melting point is achieved, without an excessively high laser output having to be provided. By means of the process and the apparatus, continuous joining is possible at high speed.

Abstract: A method and device allows dynamic mask welding with online position adjustment in the high-speed welding of structured and endless plastic films. By a transparent driven mask roller provided with masks being arranged in a passive pressure roller surrounding the mask roller, detection can take place optically, and the mask roller and consequently the mask are synchronized with the film speed. Adjustment is detached from a film transport mechanism and does not influence the welding process and in this case, above all, the speed. High film transport speeds in the range of up to 1000 mm per second can be employed.

Abstract: A method and a device for laser joining of plastics or for joining plastics to other materials, which are brought into contact with pressure, with the workpiece closest to the laser beam source being largely transparent for the laser beam, and the second workpiece being as absorbent as possible. By producing a laser beam shaped in the form of a line on the contact surface between the workpieces and by a relative movement of the laser beam relative to the workpieces, designed according to the desired joint seam structure, the workpieces are bonded together accurately only in the desired joining areas. This permits a highly accurate bonding with the smallest possible joint seam distances, so that even parts for micro-systems engineering can also be produced with a short cycle time.
