Apparatus for Winding a Sheet for Manufacturing a Secondary Battery

An apparatus for winding a sheet for manufacturing a secondary battery includes at least two bobbins and a sensor. The at least two bobbins include a traveling bobbin on which a winding process proceeds and a standby bobbin that is in a standby state during the winding process; The sensor is disposed apart from the standby bobbin by a predetermined distance, and identifies the position where the sheet wound onto the traveling bobbin will be automatically attached to the standby bobbin. When the winding process on the traveling bobbin is completed, the sheet that was wound by the traveling bobbin is attached to the outer peripheral surface of the standby bobbin, and subsequently the winding process is performed.
