<p>PURPOSE: A folding device of an electrode assembly is provided to prevent the faulty location, and to reduce the length of a buffer part, and to improve process efficiency. CONSTITUTION: A folding device includes a lamination part (400) supplying a web (200) in which an electrode with a separator is disposed; a mandrel (300) winding a part of the web in a state that a separation film is inserted; and an operation part (500) which has the rotation shaft of the mandrel, carries out a reciprocating motion in a direction parallel to the progressive direction of the web, and moves toward the lamination part when the mandrel rotates and moves back to the original position at a web supplying speed when cutting the wound web.</p> |
