Accu doct is basically used for salvaging the damaged roll and it gives the shear winding for all kind of packaging industries. Doctoring rewinder is also used for inkjet printing batch coding on printed and laminated pouches.

To understand the above techniques, it is necessary to understand the terms "Duplex" Surface Rewinding". The term Duplex Rewinding implies the use of two shafts for Rewinding the slit substrate. This ensures a positive separation between adjacent slit reels, which are wound alternately on the two shafts.In Surface Rewinding, the web is driven by the winding drum which is always in contact with the outer layer of the material being rewound. Here, it is the winding drum which is driven, also by a motor in most cases.As is clear by the above definitions, in the case of Center-Surface Rewinding, the winding force is derived from both the Rewind shaft and the contact with the winding drum. Here, both the Rewind shaft and the winding drum are driven by through a clutch mechanism and motor respectively.

This machine is of the Duplex Rewind type and is suited for finish slitting of printed and unprinted rolls of paper, cellophane, laminated paper, supported aluminum foil and other delicate materials.Salient Feature Unwind with webguideMechanical or Pneumatic BrakeEdge SensorNip RollerDancing RollMechanical or Pneumatic PressingAir Cutting or grove cutting
