Operation
Check the radius. If the desired radius has not yet been reached, adjust it by
turning the upper roller up and down. Often several operations are necessary.
It must be done carefully so as not to exceed the desired level. Once the desi-
red radius has been reached, the entire profile can be bent.
Step 11: Due to the high bending stress, it may happen that the workpiece
warps to the left or right. To compensate for this delay use the guide
rollers.

Step 13: After completing the bending process, set the main switch from "1" to
"0" to turn off the ring bending machine.

Bend long profiles
If long profiles have to be bent, please note the following.
Fig. 20: Place long profiles on additional support surfaces
Long profiles should be placed on additional support surfaces with rollers to re-
lieve these as well as the ring bending machine (Fig. 20).
Even with a vertically erected ring bending machine, additional bearing sur-
faces with rollers are to be used for bending long profiles in order to avoid
overstressing the material and the ring bending machine.
Tips and recommendations
At a vertically positioned ring bending machine to be bent
profiles are easier to edit than a horizontally positioned ring
bending machine.
