Tube unwinding and winding systems – mod. VM/I-AST – VM/I-ASB

In the evolution of processing small-diameter stainless steel tubes, manufacturers have expressed the need to monitor critical quality stages. This includes proper annealing in furnaces, welds inspections and the detection of potential tube defects through non-invasive checks, such as ultrasonic testing.

To do this, the tube – originally supplied in coils or reels – must be unwound, straightened to pass through the machines for the required treatment, and then rewound into coil or reel. The entire process operates continuously.

To meet these needs, Violi Macchine has developed two types of systems: one for processing tube coils and one for tube reels.

These systems are the result of the ongoing research and development efforts of the Violi Macchine team and the constant focus on the end customer’s requirements. As a result, technologically advanced solutions have been created, designed to ensure high standards of quality and reliability.

The systems offer precise speed control across the different units, improving the final quality of both coils and reels.

The centralized control console is simple and intuitive; via touch panel it is possible to save and recall processing recipes.

The systems work on a wide speed range. They are versatile for different tube types, processing conditions, and production requirements.

Particular attention has also been paid to safety aspects: perimeter fences protect the working area, and each station is equipped with openable guards to access machines.

The systems are built in compliance with applicable European regulations.
