摘要： Filter cigarettes which are transported sideways at the periphery of a rotating drum-shaped conveyor are engaged by successive rolling surfaces of a pair of coaxial rotary rolling members which rotate at the peripheral speed of the conveyor but in the opposite direction so that the cigarettes are caused to roll about their respective axes and cease to advance with the conveyor. The periphery of the conveyor is formed with flutes which receive the freshly rolled cigarettes, and the rolling of cigarettes is abruptly terminated by arresting members which orbit adjacent the path of movement of the cigarettes at the peripheral speed of the conveyor and in the same direction. A laser is used to make holes in successive cigarettes while the cigarettes roll about their respective axes.

摘要： Groups of coaxial filter rod sections and plain cigarettes are delivered onto the peripheral surface of a rotary drum in such orientation that each group extends in parallelism with the axis of the drum and overlies the adhesive coated outer side of a discrete uniting band which adheres to the surface by suction and is formed on the drum in such a way that its leader overlies a groove in the surface. The cigarettes of each group are attracted to the drum by suction, and the sections of the groups are mechanically urged against the leaders of the respective bands by claws which are retractible into and extendable from the drum by one or more stationary cams, followers which track the cams and gears which receive motion from the followers and rotate discs having eccentric pins coupling them to the respective claws. The claws are disengaged from the respective sections, and the ports in the surface of the drums cease to attract the cigarettes and the bands before the groups reach a rolling gap wherein they rotate about their respective axes and convolute the bands around the respective sections and the adjacent end portions of the cigarettes. The claws prevent misorientation or separation of sections from the drum when the latter is driven at a high peripheral speed so that the sections tend to fly away under the action of gravity and/or centrifugal force.

摘要： An apparatus which subdivides an adhesive-coated web of paper or imitation cork into a succession of uniting bands which are draped around groups of coaxial cigarettes and filter plugs to form filter cigarettes has two drums rotating in opposite directions about parallel axes. One of the drums is a suction drum and serves to advance the leader of the web toward the nip of the two drums where the leader is severed to yield successive uniting bands. The suction drum has a number of equidistant axially parallel peripheral grooves each disposed in front of a cutting edge. The other drum carries detachable knives with cutting edges extending beyond the periphery of the other drum so that they can penetrate into the oncoming grooves during travel past the nip. The drums are rotated by mating gears and the radius of the cylinder which is formed by the cutting edges of the knives exceeds the radius of the pitch circle of the gear which drives the other drum. The cutting edges of the suction drum form a cylinder with a radius which is equal to or somewhat smaller than the radius of the pitch circle of the gear serving to drive the suction drum. The cutting edges of the knives define epicycloidal paths during travel toward, during penetration into and during withdrawal from the corresponding grooves. Those portions of the paths which are disposed in the respective grooves resemble loops with zeniths located in the interior of the grooves or at the entrances to such grooves. This ensures that expansion or contraction of the drums cannot result in clashing of the cooperating cutting edges.
摘要翻译：将粘合剂涂布的纸幅或仿软木塞细分成一系列联合带，其围绕同轴卷烟和过滤嘴盖组成以形成过滤嘴香烟具有两个相对于平行轴相反方向旋转的滚筒。其中一个鼓是吸鼓，并用于将卷筒纸的前导件朝着两个滚筒的辊隙前进，导纱器被切断以产生连续的联合带。抽吸鼓具有多个等距的轴向平行的周向槽，每个周向槽设置在切削刃的前方。另一个鼓带有可拆卸的刀具，切割刃延伸超过另一个鼓的周边，使得它们在行进通过辊隙期间能够穿透到迎面而来的槽中。鼓通过配合齿轮旋转，并且由刀的切割刃形成的圆筒的半径超过驱动另一个滚筒的齿轮的节圆的半径。抽吸鼓的切割刃形成圆柱体，其半径等于或略小于用于驱动抽吸滚筒的齿轮的节圆的半径。刀具的切割刃在穿过相对应的槽期间和在从相应的凹槽退出时在行进期间限定了外部路径。设置在相应凹槽中的路径部分类似于具有位于凹槽内部或入口处的天顶的环路。这确保鼓的膨胀或收缩不会导致协作的切割边缘的冲突。
