- the filter elements are 2-fold Working length 72 arranged in front and the sleeves 2 times the usage length 115 arranged behind it, so that only the front filter elements 2 times the working length 72 are recognizable.
- the respective filter elements 72 and 115 then become a cone deflection drum 81 or 82 handed over, whereupon by handing over to a Transfer drum 83 and 84, the filter elements of the Main drum 100 are fed.
- the main drum 100 is not in this figure for clarity shown; however, it is schematic in FIG. 18 shown.
- Double-multiple filter 118 or multi-segment filter 118 taken over by a takeover drum 85 and one Cone deflection drum 86 supplied. Finally done a delivery to a delivery drum 87 which contains the multi-segment filter Deliver 118 to a mass flow 88. It are the multi-segment filter in this embodiment or double multiple filters 118 that have filter elements 73 at the end, then for In the middle, for example, a granulate filling having generated on the main drum 100 and in the middle the well-known filter plug or have the first filter material 19.
- FIGS. 17 and 18 There are thus three main functions in FIGS. 17 and 18, namely the supply of prefabricated sleeves 11 over a previously formed Mass flow, the supply of the filter elements, for example Soft filter elements with the help of appropriate Function groups as shown in the embodiment and the removal of the in the main drum 100 manufactured finished product via appropriate transport drums to form a new mass flow.
- the filter elements for example Soft filter elements with the help of appropriate Function groups as shown in the embodiment
