According to an exemplary embodiment of the present invention, a rolling apparatus is provided. The rolling apparatus presses an electrode sheet by passing the electrode sheet through a separation space between a pair of pressure rollers, each electrode sheet including a double-sided coating portion in which an electrode mixture is applied to both sides of a current collector and a single-sided coating portion in which the electrode mixture is applied to one side of the current collector, wherein the pressure roller includes an upper roller and a lower roller, and the upper roller or the lowerroller includes a step correction member that assigns a step to a thickness of the pressure roller, the step having a thickness corresponding to a step difference between the double-sided coating portion and the single-sided coating portion. 根据本发明的示例性实施方式，提供了一种辊压设备。该辊压设备通过使电极片经过一对压辊之间的分离空间来对电极片进行按压，每个电极片都包括其中电极混合物被施加至集流体的两个面的双面涂布部分和其中电极混合物被施加至集流体的一个面的单面涂布部分，其中压辊包括上辊和下辊，并且上辊或下辊包括台阶校正构件，台阶校正构件给压辊的厚度分配台阶，台阶具有与双面涂布部分和单面涂布部分之
