Several tube production processes require spiral movement of tubes (tube turning and moving forward simultaneously). For example, feeding systems for straightening machines or ultrasonic benches need these technologies. Simple and complex solutions have been designed, following final customer needs :
Spiral pinch rolls are easy to implement, they create the necessary movement to feed the straightening machine
Ultrasonic benches conveyors are much more complex. The accuracy of the alignment and of the thread created participates to the final quality of the ultrasonic quality control
