Latest Patents

One of Matthias Frei's latest patents is a method for the application and reading of optically readable code marks on bottles made of plastic or glass. This method involves creating depressions in the bottle's surface using a laser, allowing for the formation of diffusely scattering reflectors. A specialized sensor, constructed from optical fibers, is employed to read these code marks automatically. The design ensures that light is only reflected into the sensor at the locations of the code marks, making the application and reading process both reliable and efficient.

Another significant patent is for a resistance seam welding machine, particularly designed for the longitudinal seam welding of can bodies. This innovative machine features a secondary loop with feed and return lines constructed partially as a double line. This design minimizes voltage loss and reduces heat due to energy losses in the machine parts, enhancing the overall efficiency of the welding process.
