Reversible Inspection rewinder is a semi-automatic inspection machine which serves as a filter between Printing Machine and all other downstream processes. The output of the printing machine is screened for defects like mis-register, blade lines, shade variations, etc. with a means of a full width stroboscope.

When an operator identifies defective material, a button is pressed, the machine subsequently slows down, reverses and stops at the point where defect was identified. The defective material is then wound on a waste winder after cut and paste operations. Once defected material is removed, the web is again cut and pasted to the main rewinder.

The inspection machine helps in eliminating defective material and ensures that there is no further value addition to the defective material and increases the plant productivity by making material ready for lamination and slitting operations by removing other defects like telescoping and ovality.
