2012 Hunkeler UW6 Unwinding Module – 122023000301A

Modul: Unwinder
Type: UW6-22 7511
S/N: 15277

A responsive, productive unwinding module for rolls of up to 1370 mm in diameter. Ease of operation thanks to automatic dancer lift and operator guidance via a touch panel. A triple dancer guarantees clean paper web contact, enabling both lightweight and heavyweight papers to be processed. The dancer weight is totally decoupled by the outfeed drive, guaranteeing a seamless transfer to a high-performance digital printer.

Purpose
Continuous supply of non-impact printers off the roll over a period of several hours.

Method of operation
By pressing a switch the roll with the mandrel inserted is brought into the working position by the motor-driven mechanism. After the paper-web has been pulled in manually, initialization of the module takes place automatically. The roll is driven at the center. The unwinding speed follows the requirements of the printer, under electronic control. The paper rolls can be unwound in either direction of rotation.
