| Also , whether the belts are made out from |
- stainless steel
- carbon steel, or
- titanium
|
|
depends on the application and the required resistance. Belt material used in the wood processing industry and it’s specification
Physical and mechanical properties;

Every Berndorf Band belt is produced exactly to the customers specification.
During belt production , each belt runs as an endless unit.
This manufacturing process, only, guarantees perfect tracking and optimal flatness and almost any surface finish can be achieved. |
| Manufacturing Process of BBG Steel Belts |
| The production process of belts starts with the |
- flattening of the material and
- trimming of the belt edges
- longitudinal welding
- again flattening and
- thermal treatment of the material
- again flattening
- grinding
- or other surface treatment on request *
- trimming of both belt edges
- re cutting and milling the belt ends
- final check
- packaging of the Berndorf Band belt.

| Surface Specification |
| The surface specification available and used in the wood panel industry are |
- mill finished both sides of the belt
- mill finished one side, one side of the belt ground and/LI>
- both sides ground
|
|
The polished belt surface is required in the photo- and film industry.
( for high gloss belts )
After the required belt surface specification is achieved the belt is cut again and the belt ends are finished, such as :
- open: the belt is precut and delivered with an excess length of about 400 mm, at least. The belt has to be cut to the precise finish length when being installed ( the angle of cut : 90 degrees to the belt edge )
- prepared for welding: the belt is delivered in open condition. The belt ends are prepared for welding , the angle of cut is :
for NICRO : 80 degrees to the belt edge.
for CARBO : 80 degrees to the belt edge
for TITAN : 80 degrees to the belt edge
- endless welded: welded at Berndorf, ready to put into the machine
