A filter making apparatus includes a positioning device having a passageway therethrough, with the passageway guiding a continuous flavor element such as a continuous strand of textile material from an inlet of the passageway to an outlet of the passageway. A liquid flavorant is introduced into the passageway at a desired flow rate and the strand of material carries the supplied liquid flavorant out of the positioning device at a rate substantially equal to the desired flow rate. A portion of the passageway can form a bath of the liquid flavorant supplied to the passageway through a separate inlet at approximately atmospheric pressure. A portion of the positioning device guides the continuous strand of material through the bath, or guides the strand to pass along the bottom of the passageway, and the saturated or partially saturated strand of material then exits from an outlet of the passageway to a point in the path of filter tow material that is being converged to form a filter rod.

Cigarette filter rods having individual objects positioned at predetermined intervals therein are prepared by transferring the individual objects from a rotating horizontal pan to a rotating vertical wheel and then depositing the object into a web of filter tow. Each object is positioned within the moving web of tow. The web filter material and the objects positioned within the web are introduced into a rod-forming unit wherein the rod is formed. The rate of feed of the filter tow, the rate of rotation of the horizontal pan and the vertical wheel are controlled relative to one another such that objects are positioned at predetermined intervals along the rod. Cigarette filter elements having well controlled amounts of flavorant contained therein can be made from the rods.

Apparatus incorporating a filter tow processing unit adapted to supply filter tow to a continuous rod forming unit includes an object insertion unit that positions objects within the filter tow to manufacture a filter rod containing objects positioned at predetermined intervals. The apparatus also includes an upper hopper that acts as a reservoir for a plurality of objects, and provides for supply of objects to a lower hopper. The lower hopper is shaped so that objects are stacked therein. The bottom of the lower hopper is shaped so as to cooperate with a portion of upper region of a rotating wheel. The peripheral face of the rotating wheel incorporates a plurality of spaced pockets, each pocket being of sufficient shape and size to accommodate one object. Objects within the lower hopper are aligned in a single line along a portion of the peripheral face in the upper region of the rotating wheel. Each object then is positioned at predetermined intervals within a continuous supply of filter material. Then, the filter material is formed into a continuous rod having individual objects positioned at predetermined spaced intervals within that rod. The continuous rod then is subdivided at predetermined intervals so as to form a plurality of filter rods (e.g., four-up filter rods containing four spaced objects).

An apparatus for manufacturing a rod member for a cigarette filter element, is provided. Each rod member defines a longitudinal axis and includes a generally longitudinally-extending filter material and a plurality of objects disposed therein along the longitudinal axis. Such an apparatus comprises a rod-forming unit configured to form a continuous supply of a filter material into a continuous cylindrical rod member. An object insertion unit is configured to introduce a plurality of objects into engagement with the rod member. A rod-dividing unit is configured to divide the rod member into a plurality of rod portions such that each rod portion includes a plurality of the objects. Associated method are also provided.

A heat-insulating container comprises a paper cup body having an inner surface, an upper open end, a shell member and a bottom, the inner surface being coated with polyolefine resin, the upper open end having an outward curled portion and the shell member having a side wall on which at least one rib is formed; and a tubular member being formed of paper and having an inverse truncated conical shape, the tubular member having at a lower end thereof an inward curled portion. The tubular member is combined with an outer periphery of the paper cup body so as to come into contact with the paper cup body in contact portions provided on the at least one rib of the paper cup body and on an outer periphery of an lower end of the side wall of the shell member. According to such a structure, it is possible to provide the heat-insulating container, which has a stable heat-insulating property, a high grade design, a high degree of freedom in indication by printing on the outer surface of the container, and a lower production cost.

A spiral reverse osmosis membrane element that improves impregnation property of a sealing resin at edges of a membrane leaf and can effectively prevent micro-leaks, by using, for example, a porous support having a structure capable of sufficiently impregnating therein a sealing resin, a method for manufacturing the same, and a use method of the same are disclosed. The spiral reverse osmosis membrane element comprises a cylindrically wound body comprising a perforated core tube and, spirally wound therearound, a separation membrane, a feed-side passage material and a permeation-side passage material in a laminated state, and a sealing portion for preventing a feed-side liquid and a permeation-side liquid from being mixed together, wherein the separation membrane facing through the permeation-side passage material has a structure that a porous support and a skin layer are successively laminated on a non-woven fabric layer, and the sealing portion sealed with a sealing resin is provided at the edges of the separation membrane, wherein the separation membrane is impregnated with the sealing resin at least up to the vicinity of the skin layer through the porous support.

Means and methods for applying a tape layer from a roll to the outer periphery of a spiral wound module. In preferred embodiments the length of the tape coincides with the length of the module.
