Unwinding extra-large reels efficiently – that’s exactly why we developed the NEPATA Jumbo Companion. This unwinder extends the capabilities of NEPATA rewinders and Converting Centres to include the processing of jumbo reels.

Jumbo rolls up to 100 cm in diameter

Our rewinders are designed to accommodate roll diameters of 40 cm – sufficient for standard vinyl rolls. In combination with the Jumbo Companion, however, so-called jumbo rolls with a diameter of up to 100 cm and a weight of 500 kg can be unwound.

The Jumbo Companion can be operated on a conversion centre or on a rewinding machine. It is available in two working widths:

  • The JC1650 as a complement to all NEPATA machines in the UA1650 series
  • JC770 as an add-on to the UA770 variants

For vinyl film resellers: one machine, two uses

With the Jumbo Companion, vinyl film resellers can utilise part of their machine capacity for mass production: they source jumbo rolls directly from manufacturers and convert them into standard rolls of 25, 50 or 100 metres. Between production runs, the machine is immediately available again – without any changeover – as the usual flexible, precise and ergonomic rewinder and slitter for individual rolls and special orders.

Many vinyl films and similar products are manufactured in Asia but are primarily sold in Europe, the USA or Oceania. If a vinyl film reseller sources jumbo rolls and converts them only once they reach the destination country, up to 70 per cent of sea freight costs can be saved. To find out how this strategy can be implemented using NEPATA solutions and manageable investments, read our article ‘Reducing freight costs with jumbo rolls’.

Processing vinyl films, paper and non-wovens

Path from the Jumbo Companion to the rewinding machine

The master rolls are loaded into the Jumbo unwinder onto tension shafts with a diameter of either 3 inches or 6 inches. The material is fed into the rewinding machine from the rear via a dancer system. Thanks to a well-designed web guidance system, the material is only touched on its underside. Despite having fewer deflection points, the Jumbo Companion enables electronic web tension control even at high winding speeds. This means that the JC models can process a wide range of vinyl films, papers and non-wovens.

The following video demonstrates how this works in practice.
