Sanding becoming a standard procedure in timber construction

Contemporary timber construction

No sanding, just planed or rough-sawn? These times are long gone. Architects and customers expect best visual quality even on load-carrying components - and this means: Sanding. Kündig offers specialised wide belt sanders that can handle the weight and size of laminated beams.






Solid solution for timber construction

Due to the nature of timber construction, workpieces usually tend to be very heavy. That's why they are often being sanded by hand. Manual assembly has long been replaced by automated timber processing machinery. So why not make the next step and upgrade the sander? Industry experts agree that in addition to every automated assembly system, a wide belt sander should nowadays be included in order to work efficiently and meet the growing demands regarding surface quality.


Powerful drive for heavy tasks

The units of our sanding machines can, if useful, be upgraded to 100 kW. An economic, energy saving control system accurately adjusts the output to speed and load needed. Many options like calibration rollers, pneumatic and electronically controlled, segmented pads or brushes are available.

Thanks to the fact that only the upper machine section is moving, the working height stays fixed and the passing height allows for very high work pieces of up to 500 mm (20 inch) to be processed. Additional handling tables that allow easy handling of heavy workpieces with a forklift can be added. To facilitate handling and multiple sanding passes of heavy workpieces, there is a reverse function available which allows to reverse the conveyor direction so that workpieces can be sanded multiple times without lifting them out of the machine.


The units for our Premium series are available as steel or rubberised calibration rollers and pneumatic or electronically controlled, segmented pads. A variety of planer and brush rollers are also available. As in all of our machines, the units offer a very stable support and are made for above average lifespan. For high output applications and the belt life requirements that go with them, there are several unit heights for a variety of belt lengths (1900, 2000, 2620, 3250 mm) available.
