SP Ultraflex debuts ROBOSLIT Plus dual turret slitter rewinder with 1000 m/min speed


Mumbai-based SP Ultraflex’s participation at the 2018 edition of Plastindia was the third time the company was exhibiting at India’s flagship show for plastics and packaging. At Plastindia 2018, the company gave a live demonstration of its most basic slitter rewinder PRIMASLIT FL and the latest version of ROBOSLIT—the ROBOSLIT plus. With the introduction of ROBOSLIT plus, the series now has four variants: ROBOSLIT plus, ROBOSLIT RL (Rear Loading), ROBOSLIT OHP (Overhead Path) and ROBOSLIT FSU (Free Standing Unwind).

During the show, the focus for SP Ultraflex was also to show visitors the evolution of ROBOSLIT Dual Turret Slitter Rewinder since it was first launched in 2012. The showstopper at the SP Ultraflex stand was the ROBOSLIT plus, which ran at its maximum speed of 1000 meters per minute.

“Ours was one of the few stands at Plastindia where the machine ran at its maximum speed. In fact, to the best of my knowledge, never has a slitter rewinder been run at 1000 meters per minute at any expo at the international level as well,” says Biku Kohli, managing director, SP Ultraflex.

Kohli stresses that to make the ROBOSLIT plus run at its full speed of 1000 meters per minute for more time and get maximum mileage out of the high speed, the automation division of the company has successfully managed to shorten both the ramp up and ramp down times to 45 seconds. Needless to say, such fast acceleration and de-acceleration requires an extremely precise and responsive tension control system at both unwind and rewind ends, apart from a very sturdy and mechanically sound machine, in order to retain the stability and alignment of the substrate and avoid vibrations usually associated with such high speeds.

Talking about the response received at Plastindia, Kohli says that the company was able to book four orders for its PRIMASLIT FL at the expo. The company also got some serious inquiries for the ROBOSLIT plus, and is bullish about some of them converting soon.

“Quite a few inquiries were received for the ROBOSLIT plus and we expect this machine to join the mainstream sooner than foreseen. We are targeting our current customers as well as new customers for the ROBOSLIT plus. Given the premium nature of this model, we can see a lot of discerning customers opting for this machine instead of a European brand,” he says.

Kohli shares that six ROBOSLIT slitter rewinders are under manufacture and will be supplied to customers by the middle of this year.

Not only did SP Ultraflex have a healthy footfall at its PLASTINDIA stand, the company was also awarded exhibitor’s award for the best stand.

Exhibiting the ROBOSLIT Plus overseas
With the launch of the fully loaded ROBOSLIT plus, SP Ultraflex now rubs shoulders with leading European brands, prompting them to turn their vision to international events as well.

“We are very keen to show this machine at a premium international event soon. We have not taken a final decision, but it will be either interpack or K or even drupa,” he informs.

The Covid-19 pandemic led to the country-wide lockdown on 25 March 2020. It will be two years tomorrow as I write this. What have we learned in this time? Maybe the meaning of resilience since small companies like us have had to rely on our resources and the forbearance of our employees as we have struggled to produce our trade platforms.

The print and packaging industries have been fortunate, although the commercial printing industry is still to recover. We have learned more about the digital transformation that affects commercial printing and packaging. Ultimately digital will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future.

Web analytics show that we now have readership in North America and Europe amongst the 90 countries where our five platforms reach. Our traffic which more than doubled in 2020, has at times gone up by another 50% in 2021. And advertising which had fallen to pieces in 2020 and 2021, has started its return since January 2022.

As the economy approaches real growth with unevenness and shortages a given, we are looking forward to the PrintPack India exhibition in Greater Noida. We are again appointed to produce the Show Daily on all five days of the show from 26 to 30 May 2022.
