Since the turn of the century tubes have been industrially manufactured on tube winding machines. In order to cope with the steadily increasing demand of spinning mills for small tubes, a different and faster production technique had to be developed. Paperboard was wound onto a wooden core on a rotating axle and the layers were glued together. KLUG-CONSERVATION tubes are made from ageing resistant, spiral-wound, natural white coloured paper plies. Tube caps made of age-resistant cardboard or PE can be ordered separately.
