Constant passline height

Manufacturer-independent designation for constant height of the machining table.

The desired workpiece thickness is set by raising / lowering the processing units. As this is more complex in terms of design than a lifting table, the working height of many wide belt sanders is set by adjusting the height of the working table.


  • Machines with constant passline height can be integrated more easily into lines/ chains, as the workpieces are always transported at the same height.
  • Work-saving devices (roller tables etc.) need to be adjusted in height only once.

Alternative terms

  • Constant working height
  • Constant table
  • Machine head adjustment at constant working level, Fa. Kündig
