Glazing bead cut-off saw

  • Optional vertical saw aggregate (clocked) for the longitudinal cutting out of strips of glass on moulders or angle plants in wooden window production.
  • Arranged as the last horizontal aggregate, axially clocked in connection with glazing bead guides and slide or ejector.


  • In the 1980s, the profiling and separation of the glazing beads from the inner profile of a wing was usually done on an angle plant, or moulders had to be expensively readjusted between the planing of planks with and without glazing bead trimming. This was no longer necessary when machines with controlled axial timing were introduced on the market, which was also induced by the general change to on-time production.
  • Since the early 1990s, the technology of profiling and trimming glass beads already when planing the planks has succeeded in wooden window production on moulders. This technology was sold particularly often with the craftsman machine Profimat 23 from Weinig. The background for this concept is the need for additional glass beads because of errors in the wood. From the 8 necessary window planks for one wooden window, theoretically, 7 glass beads can be separated out. With the new concept, ready, profiled glass beads have also been cut out of the lateral and upper frame planks.
  • On the right and upper spindle, planer head/ saw blade/profile milling combinations have been mounted. Because of the axial timing of the spindles, the planks could be planed on four sides or the glass beads could be profiled and cut out. There might be an additional saw aggregate behind the upper spindle which finished the cutting out. Using glass bead guides and slide or ejector, the glass beads were separated from the planks at the machine outlet.
  • This concept was also used by the company SCM for its machine Superset 23.
  • Since the mid-1990s, Weinig had changed the concept, starting with the series Unimat 23 E, and only cut out unprofiled square bars, because the ever increasing number of different glass bead thicknesses and profiles resulted in an extreme increase of the set-up times due to tool changes. However, the further processing of these bar blanks requires an additional working process for profiling. This however, offers the advantage of always having sufficient, high-quality glass beads available (pre-sorting of the blanks).
