Summary:A process of producing a filter tube comprises the steps of cutting a paper segment 18 of given length and width from an endless paper supply. Next, a solid filter 14 of cellulose acetate tow, for example, is centrally positioned on the paper segment. Opposed tube forming rollers 20,22 engage the ends of the solid filter, and as these rollers rotate, the paper segment is formed into a tube shape. Overlapping portions of the paper segment are secured together, and the tube forming rollers are withdrawn from the tube to thereby complete the forming operation. ® KIPO & WIPO 2008
