The drum is mounted securely and expeditiously using barrel arms. At the control panel, the drum can be turned forwards or backwards in manual mode. The unwinder is controlled automatically in a line operation
The drum with the winding material is rolled by hand to the loading place after opening of the protective hood. The previously opened centre sleeve arms are then moved together to the corresponding take-over position by the operator's push of a button. When the drum is clamped by the centre sleeves the same move upwards in winding position. On the operating panel the drum can be turned forward and backward in manual operation. When operating in a line, the unwinder (Pay-off) is then automatically controlled. A prerequisite for this is that the protective hood is closed.
