- the conveyor belt 120 or a variety of Conveyor belts 120.1-120.3 are or are moved in the conveying direction 130 via a drive wheel 121 and a deflection wheel 122.
- a vacuum box 123 is provided, the function of which is described in more detail below with reference to FIGS. 12 and 13.
- filter segments After depositing all filter segments, which are intended for a multi-segment filter or a double multi-segment filter, they are transferred to the known reversing drum 28 by means of a transfer drum 63.10 and a further transfer drum 63.11, in order then to use wrapping material around a continuous filter strand in a longitudinal axial process for example in the applicant's known KDF machine.
- a cleaning box 124 is also provided, by means of which the conveyor belt 120 or the conveyor belts 120.1-120.3 can be cleaned, specifically in a position in which there are no filter segments in the troughs. Blown air can be used for this purpose, for example. '
- FIGS. 12 a) and 12 b) schematically show how the filter segments are fitted in one exemplary embodiment, the associated vacuum box 123 being shown in FIG. 12 b) ; i st.
- the conveyor belt 120 moves in the conveying direction 130.
- corresponding vacuum openings 132 are shown which, when acted upon by vacuum, result in filter segments 83.1-83.4 being held in their position on the vacuum opening 132.
- Position A corresponds to the position in which the switch! ement unit 605.6 places a filter element 83.1 approximately centrally on the conveyor belt in a corresponding receiving trough 131.
- two hard elements 83.2 in Area of the hard element unit 61.3 deposited on the conveyor belt at B.
- the filter elements 83.1 and 83.2 are then pushed together by means of a first sliding element 134.
- two soft filter elements 83.3 are placed outside around the already deposited filter elements, namely in the soft element unit 605.5 and at position C. These soft elements are also pressed onto the previously deposited filter elements by means of a sliding element 135.
- Soft element 83.4 is deposited in soft element unit 605.4 on the left side at D and then pushed together by means of a sliding element 136. This results in a filter rod group 27.
- FIG. 12 b there is schematically an arrangement of a vacuum opening 133.1 of the vacuum box 123! shown, some vacuum openings 132 are also shown in the associated receiving troughs 131 for the sake of illustration. It can be clearly seen that the vacuum opening 133.1 widens in the conveying direction in such a way that the respectively deposited filter elements 83.1-83.4 can be subjected to a vacuum.
- FIGS. 13 a) and 13 b) show another embodiment according to the invention of covering filter elements on a conveyor belt 120 or, as shown in FIG. 13 a), on six conveyor belts 120.1-120.6.
- the external filter elements are placed on top and the internal filter element at the end.
- the sliding element 137 pushes the filter elements together to form a filter rod group ! 27 instead.
- Fig. 13 b) is also the vacuum opening 133.2 shown, which corresponds to this type of filter assignment of the conveyor belt (s).
- the devices or devices according to the invention mean that very little mechanical engineering is required. There is also a low functional risk, since known methods are used in some processes, such as in particular the known strand method or, for example, the method which is described in DE-OS 24 52 749 and which is used in the applicant's strand machine KDF.
