Embodiment Construction

[0028] Figure 3 shows a known device for producing discrete composite filter rods, of the type sold under the model ND-3 by Japan Filter Technology Co., Ltd. (JT Group) and manufactured by Sanjo Machine Works Co., Ltd. of Japan . The known device comprises a combination device 10 comprising a delivery wheel 12 which arranges a plurality of different filter rod segments 2, 4 to a first endless belt in a preselected assigned configuration such as that shown in Fig. 1a Type conveyor 14. The different filter rod segments 2, 4 are conveyed from two or more bins or hoppers to the delivery wheel 12 by a series of conveyors not shown. When the filter rod segments 2 , 4 are conveyed to the first endless belt conveyor 14 , they are pushed against each other to form a continuous flow 16 . A first belt conveyor 14 conveys the abutting filter rod segments 2, 4 to the top of a continuously running paper web 18 drawn from a paper tray (not shown). The paper web 18 with at least a portion ...

Abstract

Apparatus for the production of combined filters or recess filters for cigarettes is disclosed, the apparatus comprising: a feeder (12) for feeding a plurality of filter segments (2, 4) along a path; a wrapper downstream of the feeder (12) for wrapping the plurality of segments in a web of material (18) to form a rod (20); a combiner (52, 58, 68) operative at a location between the feeder (12) and the wrapper for forming a stream of aligned segments from the plurality of segments (2, 4) and for transporting the stream of aligned segments along the path to the wrapper, and cutting means (24, 28) for severing the rod (20) into a plurality of discrete rods each comprising a plurality of segments, the combiner (52, 58, 68) being adapted to maintain the alignment of segments in the stream of aligned segments as it transports the stream of aligned segments to the wrapper so that, in use, relative movement of the segments in the stream is substantially prevented over the entire length of thepath from the combiner to the wrapper.

Description

technical field [0001] The present invention relates to a device and a method for producing a rod comprising a plurality of segments, in particular for the manufacture of composite filters or recess filters for cigarettes. Background technique [0002] Cigarettes generally comprise a wrapped cigarette, optionally tipped with a filter. The filter may be a composite multicomponent filter comprising a plurality of filter rod segments. The filter rod segments making up the composite filter may comprise different filter substrates, or may comprise the same filter substrate but with alternating segments doped with particulate matter. Figure 1a shows a composite filter plug comprising interleaved cellulose acetate segments 2 and cellulose acetate segments 4 doped with carbon particles. Composite filters may include filter rod segments formed by air gaps, slots or cavities adjacent to or between other rod segments comprising the composite filter, which may be filled with particles...
