Stationary Mandrel
Figure 5
A roller mandrel is mounted to the roll stand. It is inset into a conventional roll to form an air bend.
In many cases an air bend can be accomplished effectively with a stationary solid mandrel mounted in a conventional roll (see Figure 5). It combines both the roll and mandrel features. The roller and mandrel are attached to the roll stand. The roller is captive. The hole on the mandrel is more than a half circle, which keeps it in place horizontally, and the set screw prevents the roller from escaping vertically.
