The NEPATA UA770 Coreless is a specialist in coreless winding for a web width of 77 cm – for all applications where no core is required during rewinding.
For short rolls of vinyl film, paper and wallpaper
Whether it’s flock film, flex film or HTV: for rolls with very short lengths, a paper core is not strictly necessary. This applies all the more to wrapping paper, wallpaper, baking paper or barbecue paper. Water-activated adhesive tapes can also be wound without a core.
Particularly tight winding
Core-less winding is generally possible with all NEPATA rewinders. However, this requires replacing the standard 3-inch shaft with a special 2-inch shaft. With the UA770 Coreless, this step is not required, as it is designed from the ground up for coreless winding. Above all, however, the internal diameter after winding is only approx. 33 mm.
Fast and accurate
With a winding speed of up to 1.0 m/s, the UA770 Coreless achieves a high production capacity:
- approx. 140 rolls per hour, each 3 m long
- approx. 160 rolls per hour, each 1.5 m long
- Deviation during rewinding and automatic cross-cutting of less than 2 mm per metre
Quick payback
As well as its powerful features, it is above all the avoidance of errors and waste that ensures a rapid return on investment – not to mention the fact that doing away with cores saves considerable costs in its own right. You can read more about the concept in the Coreless fact sheet.
