The UA770 Coreless is a rewinding machine for coreless winding of media with a web width up to 77 cm. The inner diameter of the wound rolls is approx. 33 mm. The pneumatically activated one-sided tension shaft holds the material securely and reduces the outer diameter after the winding process so that the roll can be easily removed. A conversion kit for clamping 39 mm and 2″ diameter sleeves, is optionally available. The unwind offers a tension shaft with a 3″ mount also on one side, other diameters are optionally available. The UA770 Coreless features a pre-feed unit with digital measuring system, optical media edge detection, and an automatic cross cutter that automatically cuts the material to the exact length. The rewinding machine unwinds reliably, precisely and quickly from film rolls up to a maximum diameter of 400 mm and unwinds exact short rolls up to a diameter of 100 mm. In combination with the ConvertPlus control software, both parent and customer reels can be provided with individualized barcode labels containing the run length of the film, article data and, if required, much more information. With the help of these barcode labels, the films can be scanned before running a rewind job and thus the article data can be checked and the remaining length of the roll can be read into the system. This avoids many errors in the rewinding process. The ConvertPlus supports several ways to read in rewind orders – for example, via scanning of corresponding barcodes on the delivery bills or even via fully automatic imports of electronic order data.

“The UA770 Coreless is the machine for winding without a core, because short rolls often do not need a cardboard core. Ideal e.g. for wrapping paper, because the inner diameter after winding is only approx. 33 mm.”

Simone Zopik (Sales Manager)
