151 153 153/1 NON MANDREL FORMERS ® <strong>Ercolina</strong> non mandrel machines are supplied with the most advanced tooling technology, developed by thirty years international market experience and reaserch. A complete set of tools is made up of two main components, the former that shapes the curve turning round together with the machine rotating shaft, and the counterbending die (or in particular cases the roll) that is moved towards the profile to block it during the bending phase.

The selection tables on pages 67, 68, 69 will guide you through former choice, other tables for counterbending die selection are on pages 84 and 85.
