Embodiment Construction
[0020] The embodiment shown in Figure 2 shows a preparation and feeding device comprising a vertical storage tank 11, in which the fibrous material is conveyed pneumatically in an air stream from the starting box 6, and is used, for example, as already described in the cited patent EP1.004.693 The fill level control technology accumulates in the end of the reservoir.
[0021] At the bottom of the drum 11 there is provided a feed drum or roller 12 which feeds the tuft fibers to an equipped drum 13 which unwinds the material and opens and cleans the picked tufts. The two drums 12 and 13 work together in rotation to take up the material and feed it forward.
[0022] The feed rollers 12 are actuated at variable rotational speeds and are made toothed or provided with serrated wires in a manner known per se. The feed rollers 12 work against the wall 14 of the end of the drum 11 to create a gap 15 between them for the passage of the fibers.
