Rewinding Machine (Doctoring Machine)

We have designed this rewinding machine keeping in mind the required parameters of our clients. These rewinding machine perform the function of salvaging and rectifying printed and un-printed substrate after slitting. The rewinding machine is of cantilever construction, so that he loading of the parent reel and unloading of the rewound reel is both convenient and easy.

Both the rewind and unwind shafts are mechanically flexible & therefore, the core locking and unlocking can be achieved by, screwing and unscrewing a pair of nuts. There is a pair of precision machine steel plates, braced together with tie rods and channel suction base, which forms the support structure of the machine.
We have specially designed our rewinding machine with unwind shaft and braking drums attached to the sliding plate which oscillates feeding on linear motion of the ball bearings.

The preferred braking torque on the unwind reel can be manually applied through a shoe brake requisite. The machine is provided with a number of web support rollers that aids in smooth web flow before the rewind shaft. Our engineers have maneuvered the web in a manner that the sensor of the pneumo hydraulic edge guide can be conveniently altered as per requirement. We have availed AC DRIVE variable speed for smooth operation of the machine (with soft start) in the range 0-120mtr/minute along with cantilever type roll loading and unloading system.. We also have the provision for Inkjet Printer to be mounted on this machine.
