    • Apparatus and Method for Filter Manufacture A filter rod for a smoking article comprises an extruded hardened inner core of a first filter material and an outer core of a second filter material which surrounds the inner core. The second filter material is of a softer texture than the first filter material. The filter rod further comprises a plug wrap around the outer core. Also, an apparatus for manufacturing such a filter rod comprises an inner duct having an inlet to receive a first filter material including a plasticiser and an outlet through which the first filter material is expelled. An outer duct has an inlet to receive a second filter material and an outlet through which the second filter material is expelled. The inner duct is disposed within the outer duct to enable formation of a continuous body of filter material comprising an inner core of the first filter material surrounded by an outer core of the second filter material. A wrapping station is disposed proximate the outlets of the inner and outer ducts to provide a plug wrap around the continuous body of filter material. The inner duct includes at least one steam inlet for the introduction of steam into the inner duct to heat the first filter tow material as it is conveyed through the inner duct to form a hardened inner core. Also a method of manufacturing such a filter rod is described.
    • 用于过滤器制造的装置和方法用于吸烟制品的过滤杆包括第一过滤材料的挤出硬化内芯和围绕内芯的第二过滤材料的外芯。 第二过滤材料具有比第一过滤材料更柔软的质地。 过滤杆还包括围绕外芯的塞子包裹体。 而且,用于制造这种过滤杆的装置包括一个内部管道,该内部管道具有一个入口,该入口用于容纳第一过滤材料,该第一过滤材料包括一个增塑剂和一个第一过滤材料被排出的出口。 外部管道具有用于接收第二过滤材料的入口和第二过滤材料通过其排出的出口。 内部管道设置在外部管道内,以形成连续的过滤材料主体,该过滤材料包括由第二过滤材料的外部核心围绕的第一过滤材料的内部芯体。 包裹站靠近内管道和外管道的出口设置以围绕过滤材料的连续体提供塞子包裹。 内部管道包括至少一个用于将蒸汽引入内部管道的蒸汽入口,以在第一过滤器丝束材料通过内部管道输送时加热第一过滤丝束材料以形成硬化的内部芯部。 还描述了制造这种过滤杆的方法。

    • An adhesive applicator (1) for applying adhesive to a tensioned web of tipping paper (7) as it moves through a smoking article filter assembly unit is disclosed. The adhesive applicator comprises a transfer roller (4) configured to transfer adhesive from an adhesive reservoir (3) onto a surface of a moving web of tipping paper (7) in contact with said transfer roller (4) as the transfer roller rotates, and a suction roller (11). The suction roller (11) is configured to enable a region of low pressure to be generated that is operable to suck a web of tipping paper (7) against the suction roller (11) to move the web as the suction roller rotates. A method of applying adhesive to a tensioned web of tipping paper (7) moving through a smoking article filter assembly unit is also disclosed.
    • 公开了一种用于当粘合剂移动通过吸烟制品过滤器组件单元时将粘合剂施加到卷边纸(7)的张紧网上的粘合剂施加器(1)。 所述粘合剂施加器包括转印辊(4),所述转印辊(4)被配置为当所述转印辊旋转时将粘合剂从粘合剂储存器(3)转移到与所述转印辊(4)接触的接装纸(7)的移动幅材的表面上,以及 抽吸辊(11)。 抽吸辊(11)被构造成能够产生可操作的吸收卷筒纸(7)的腹板靠在吸辊(11)上的低压区域,以在抽吸辊旋转时移动卷筒纸。 还公开了一种将粘合剂施加到移动通过吸烟制品过滤器组件单元的接头纸(7)的张紧腹板上的方法。
