Optimum results with large quantities. A clear-text display on the 15" touch-screen monitor gives the operator all of the information he needs. This means, that the data records stored in a window construction program, are read in order related, and that the profile data are visually displayed. A further innovation is the integrated profile-height-measuring system. Due to the cutting optimisation system, the user interface guarantees the efficient use of the material. Remaining parts of sufficient length are marked with printed labels and scanned for further use.
