    Abstract: PURPOSE: To provide a method for applying cellulosic slurry to banded smoking article wrappers with repetitive patterns. CONSTITUTION: Utilizing a screen roller 60 having a surface 51 including alternating regions of a screen section 64 separated by a spacer 66, cellulosic slurry is applied onto a pulp web 21 moving along a path to form repetitive patterns. Utilizing a slurry coater 46 including a slurry feeder 47, a knife 48 and a slurry return 49, a continuous thin layer of the slurry is applied to the surface 51 of the screen roller 60, and the slurry is allowed to adhere to only the screen section 64 by the vacuum force provide by a vacuum port 54. The roller 60 is rotated so that the adhered slurry moves to a region 51B adjacent to both the web 21 and a pressure port 52, and then the pressure port 52 forces the internal surface of the screen section 64 to release the slurry from the screen section 64, applies the released slurry to the web 21 and forms the repetitive patterns. The preferable widths of the screen section and the spacer range are 2-8 mm and 12-20 mm, respectively.

    Abstract: PURPOSE: To improve a mechanism for applying a tension imparting adhesive to the tape advancing to the mandrel of a spiral tube winding machine. CONSTITUTION: One or more tapes 12a, 12b, 12c, 12d, 12e pulled toward the mandrel of a tube winding machine are passed on vacuum chambers 24a, 24b, 24c, 24d, 24e to receive tension. An adhesive is applied to one or more tapes present at a place near to a vacuum chamber. If the tube winding machine is stopped by any reason, the vacuum chamber holds the adhesive coated tapes to a tensioned state and these tapes move to be detached from the contact with an adhesive coating member. The lengths of the respective tapes being in contact with the adhesive coating member are adjusted to adjust the amt. of the adhesive applied to the tapes. In order to accelerate the effect of the adhesive, the respective tapes are heated after the coating with the adhesive.
