Manufacturing Technology

As more and more industries demand high-quality screws and have an ambitious aim to make the set-up of rolling machines perfect and 100% independent from operators, EVIRT Italia has developed the patented optical auto-pitching system.

Registered under European patent number 16176153.4 – ‘Procedure to automatically match the rolls dies using optical system’, the optical auto-pitching system is able to automatically measure, calculate and position the most reliable dies’ rolling positions both on two and three die rolling machines.

Lasting less than a minute, Evirt Italia Srl says the patented system is not only 100% precise and fully reliable, but it also does not require any operator skill or material waste – ensuring a 100% perfect matching position between the two or three rolling dies.

By starting the dedicated machine’s program by a simple touch on the myEvirt HMI Interface, the smart rolling machine automatically performs the matching analysis at the end of which the perfect dies’ angular positions are set and the machine is fully ready to be used.

“The invention is epochal indeed from today no more chips during rolling process can be attributed to dies’ mismatch,” says Mr Januszek, sales manager at EVIRT Italia. “The patented optical system will soon be available on all the new smart rolling machines series 2022 – providing a great opportunity for fastener producers all over the world to highly improve the quality of their rolled components.”
