In 2000 Giben introduced the PM System, a breakthrough in panel sizing.

By this innovation Giben won the "Challengers Award" at IWF 2000 (Atlanta, USA), the industry's highest honor recognized worldwide for best advancements in technology in the woodworking machinery field.
The PM System (PM stands for "Pinze Mobili", in English: Moving Grippers) is a new and revolutionary system of moving grippers using controlled positioning, integrated in a process of high automation, to add the maximum flexibility to the production environment.
  

The PM System uses two types of grippers:

The "X" type gripper only moves along the width of the pusher. The "XY" type gripper moves along the width of the pusher but can also move perpendicular to it, and therefore can adjust the positioning of a stack of panels or strips at a distance from the cut line different from the distance determined by the "X" type grippers.

These grippers position automatically, controlled by the saw computer. The position is always optimized depending on the job, the size of the boards, the cut sequence, the size of the strips, or the size of the parts




 

 


The innovative advantages introduced by the Giben PM System are:


  • Higher productivity
    It is possible to cross cut more strips by side without the need to add any fixed additional grippers, because the grippers are always placed in an optimal position for the cutting pattern in execution.

  • More logical machine cycles
    The moving grippers with automatic positioning group more strips together allowing a more logical material handling.

  • Simultaneous staggered cuts
    With the combination of "X" and "XY" type grippers, full stacks of panels in a staggered pattern can be cross cut and moved as if it were a checkerboard pattern. A single line panel saw can now match outputs that in the past were reserved to angular sizing plants only.

  • Optimization without limitation
    There is no limitation as to the patterns that the machine can process, because the "danger" areas of fixed position grippers have been eliminated by the PM System.
    Cutting of rests even of small size is always optimized.


  • No damage to the corners of the panels
    Panels often suffer the problems of corner damage due to fixed position grippers. This problem is fully removed by PM System, as it allows a proper positioning of the grippers in relation to the changing dimensions of panels and cutting patterns.

  • Fewer number of saw carriage and pusher movements
    As more strips can be placed side by side this translates into a fewer number of cycles and movements of saw carriage and pusher.

  • Long term solution
    There is no need to replace or modify the machine as the panel format needs change. PM System is the solution which allows the machine to meet the needs of today and tomorrow.
