Doctoring Machine

The DRM REV is a reversible coil rewinding machine which after running in one direction, can be reversed to restore the salvaged reel to its original direction at speeds of upto 500 mmin. The need to unload and reload the coil as in the case of unidirectional machines no longer remains, allowing the user to rewind more reels with minimum effort in a given time. Besides restoring the reel direction, the reversible feature is also used intermittently to reduce the doctoring time for reels telescoped only in part and the removal of material with print defects to obtain a defect free roll for onward supply to the customer.
