Machine concepts
On the basis of the following machine concepts we find the optimum solution for you:
- Suitable for a wall thickness of up to 150 mm
- Pre-bending of conical shell sections is possible
- Automated positioning device for the plate handling during the pre-bending process
- Simultaneous pre-bending of both plate sides
- In contrast to the conventional roller pre-bending methods, there is no roll-out of the plate edges and no crushed edges
- Prevention of plate waviness in the pre-bent edges which leads to a zero gap without edge offset for an optimum weld seam preparation
- Suitable for various materials and especially for the forming of Clad pipes
- Particularly suitable for plates with increased wall thickness in high steel qualities and special grades
- Cost-efficiency due to innovative tool design and minimum re-working
- Patented 4in1 Graebener® technology for highly flexible production
- Combines the advantages of calibration and straightening press with those of the 2-side pre-bending press
