Abstract: Apparatus and method for folding a sheet material, preferably an electrode sheet, into a fan-fold orientation. A securement means secures a portion of the sheet material to a rotatable plate in a plane parallel to the rotatable plate. A rotatable releasable clamp secures at least a portion of the sheet in a first rotational position between the plate and clamp. A rotation means rotates the securement means, plate, and clamp so as to move the sheet from the first rotational position to a second rotational position, wherein, rotation from the first rotational position to the second rotational position forms a folded portion of the sheet over a portion of the clamp.
