Summary:Method and apparatus for forming filter tubes comprises delivering a filter element to a flute on a first drum having vacuum for securing the filter element thereto. First and second tube forming rollers axially engage opposite ends of the filter element. A second drum accepts and cuts a continuous paper web with a glue pattern thereon into paper pieces, and a cut paper piece is delivered to the filter element. The paper piece is then rolled around the filter element and the tube forming rollers to form a cylindrical shape. The tube forming rollers are axially disengaged to thereby produce a filter tube with hollow ends and a control positioned filter element.
