Abstract
An apparatus and method provides for rotatably cutting and/or laminating layered structures or sheet material supported by webs. A rotary converting apparatus and method of the present invention converts a web comprising a cathode layered structure and a web comprising an anode layered structure into a series of layered electrochemical cell structures supported by a release liner. Employment of a rotary converting process of the present invention provides, among other benefits, for the creation of a product having a finished size, without need for downstream or subsequent cutting.
