Abstract
An apparatus for generating a roll map of a merge-wound electrode includes a position measurement device configured to acquire coordinate value data for a longitudinal position of an electrode according to an amount of rotation of the rewinder. The apparatus includes an input device configured to input an input signal indicating a start of merge-winding or an end of merge-winding, a seam detector configured to detect a seam, a reference point detector configured to detect a plurality of reference points of the merge-wound electrode, and a roll map generator configured to generate a roll map for simulating the merge-wound electrode moving in a roll-to-roll state based on the input signal of the input device, and to display the longitudinal coordinate values of the electrode, the electrode coordinate values of the seam, and the electrode coordinate values of the plurality of reference points of the merge-wound electrode on the roll map.
