BÜLTMANN Expanderande draglåsning
This system is appropriate for drawing not pointed tubes. Single and/or multiple internal gripper systems are used.
Due to manual or automatic quick changing systems the tube drawing machines can either be operated with a standard external drawing gripper or with a tube internal gripper system.
Advantages:
- The pointing operation is no longer necessary, therefore the tube handling and conveyance as well as additional intermediate storages are eliminated.
- Material saving because the drawing tag to be cut off is more than 50 % shorter as the standard drawing tag when using the internal gripper system.
