The concepts of the Graebener® roll bending machines are based on decades of experience, in the area of roll bending machines even reaching back as far as the 1970ies. As custom machine builder our aim for each project is to use this experience to design an individual concept which is ideally customized to your requirements.
Depending on the type of application we use various concepts when designing your solution, one of these concepts being the supporting yoke technology.
The supporting yoke turns your Graebener® 4-roll bending machine into a versatile multipurpose machine. It supports the comparatively small rolls during the pre-bending process. The supporting yoke clamps the top and bottom rolls thus counteracting a deflection by applying counterpressure to the rolls. This way, the pre-bending power of the roll can be increased. Straight ends no longer need to be flame cut, since they are reduced to a minimum. This saves time, improves the production capacity and enhances the economic efficiency of your production.
When the supporting yoke is not needed for production, it can be completely sunk into the foundation. This way, a plate can be bent in the machine as if no supporting yoke was installed.
