Rotoflex Redesigns VLI Finishing System


ST. LOUIS, MO | Rotoflex has redesigned the VLI inspection/slitting/rewind system, reportedly impacting material waste and time waste, operator interaction, and web path access.

The new design is driven by the Rotoflex eDrive 2.0 web handling system, which company says increases production speeds, gives more precise speed control and accurate stop/start ability, and provides better tension management to deliver higher roll quality. The 2.0 system is said to make the VLI an ideal solution for many applications, including paper and film labels, unsupported film, tension-sensitive materials, and various specialty substrates.

To improve operator use and interaction, a large 15-in. (381-mm) monitor displays key functions at a glance, and tactile controls are positioned for easy access. The lower working heights of the machine offer more comfortable viewing of the web, splicing, and slitting. Integrated dashboards with tool pockets ensure key controls and tools are well within reach.

The new web path of the VLI improves access to the web, allowing fault placement in multiple locations and maximizing setup and changeover efficiency. The VLI is available in widths to 28 in. (718 mm) and powered by Genesis, the Rotoflex advanced control system.

"Changing dynamics in the printing and converting operation inspired our engineers to re-think the inspection/rewinder's role in the print-to-finish workflow," says Kevin Gourlay, business director at Rotoflex. "By implementing equipment like the VLI into the finishing operation, converters can realize an increase in capacity of more than 300 additional jobs per shift, per year on a single machine."
