Embodiment Construction

[0046] Figure 1 shows a schematic diagram of the process in the tobacco processing industry from preparation to manufacture of a filter rod. Process operations can be changed in different ways. In the example of FIG. 1 , fiber preparation 1 takes place first, in which mainly the compacted stock shape of all fiber materials is transformed into a thin wool state. A loose mass of fibers forms here. In addition to these fiber clusters, already individual fibers can also be produced. Fiber Prep 1 for example utilizes a figure 2 device is carried out. Such devices are known per se. Compacted stock shapes are, for example, fiber bales, fiber mats 10 or fiber mats 10 . The fiber bales are usually separated by means of a loose bale machine, while the fiber mat 10 or fiber mat 10 is separated by means of a hammer mill 13 .

[0047] Unpressed fibrous material placed in tight packs also expands loosely and fluffy at the time of fiber preparation. Loose balers for fibrous materials ...

Abstract

The invention relates to a method and a device for processing fibers of limited length to produce filters in tobacco processing industry. Said device comprises at least one unit (115) for dispersing fibers (10, 29, 31, 40 - 44, 53) of limited length and at least one metering installation (111 - 114). Wherein at least one component (17, 19, 28, 29, 39, 55, 56, 63) is disposed for transferring fibers from the at least one metering installation (111 - 114) to the at lest one dispersing unit (115). The invention is characterized in following steps: transferring fibers of limited length (10, 29, 31, 40 - 44, 53, 65, 75) to the dispersing unit (115); dispersing the fibers (10, 29, 31, 40 - 44, 53, 65, 75); transferring dispersed fibers in a direction toward a rope-forming unit (89). The device disclosed is characterized in that filer material (10, 29, 31, 40 - 44, 53, 65, 75) comprising limited fibers (10, 29, 31, 40 - 44, 53, 65, 75) are processed, and the dispersing unit (115) can substantially completely disperse fibers of limited length.

Description

technical field [0001] The present invention relates to a method of processing finite length fibers for the manufacture of filters in the tobacco processing industry. In addition, the present invention also relates to a processing device for manufacturing finite long fibers for filters in the tobacco processing industry, comprising at least one device for dispersing finite long fibers and at least one metering device, wherein at least one is provided for obtaining from at least one The metering device delivers the finite length fiber element to at least one dispersing device. Background technique [0002] GB718332 discloses a method of processing filter material for manufacturing filters in the tobacco processing industry and a corresponding device for processing filter material. Here, the material is cut into chips by means of a tobacco chopper and conveyed to a rod making machine similar to a rod machine, where the chips are impregnated with a chemical to prevent unsatisf...
